3. Components

3.1. Included in DeliveryThe following components are included in delivery:

• One TS 800 SDI sensor

• Two TC 30 SDI connections cables

• One BatteryPack

• One recharge power adaptor

• One equipment bag

A T2000 multifunctional measuring instrument is also required for use.

An extra TC 30 SDI connection cable can be used as a cable extension for the TS 800 SDI.

3.2. Test GasNever use pure hydrogen! A mixture 95% nitrogen and 5% hy-drogen is recommended as test gas. This gas mixture harboursno danger of fire or detonating gas developing, and is availablefrom many gas suppliers a as a standard forming gas.

The test gas is not suitable for calibration purposes. Calibration

gas should always contain oxygen. We recommend B. 50 ppm

hydrogen in synthetic air as calibration gas.

4. Intended Use

The TS 800 SDI sensor does not serve for absolutely deter-

mining the hydrogen content, but for damage-free location of

leaks in purged systems via indicative measurement of the dif-

ferent hydrogen concentrations.

5. Function

The TS 800 SDI is mainly suitable for detecting hydrogen (H2)

and, in a limited manner, i.e., undefined manner, for detecting

slightly volatile, flammable gases and hence identifying and lo-

cating leaks.

Hydrogen is used as a trace gas for locating leaks with the TS

800 SDI, because it is not only the lightest, but also the most

inexpensive of all trace gases, and is also completely safe

when used in a mixture of 5% hydrogen and 95% nitrogen.


This environmentally-friendly gas mixture is non-flammable,non-poisonous and non-corrosive!

Due to its extremely small molecule size and high rate of diffu-sion, the hydrogen contained in the test gas escapes throughthe tiniest opening into the ambient air after the system to betested has been filed with it.

These could be splits in the outside skin of pressurised con-tainers, pipes tanks and so on. The hydrogen also quickly andeasily permeates through surrounding and covering materialsuch as earth, insulation and coating materials (jointless floor-ing, plaster, mineral joint materials).

The materials listed last above usually have structural proper-ties, which permit diffusion of the hydrogen to the surface andtherefore in the ambient air. This allows hidden leaks such asin facility equipment to be narrowed down by detecting escap-ing H2trace gases or even located exactly, without large areasof the surrounding material needing to be destroyed.

The high precision resolution of the TS 800 SDI sensor systemsallows even the smallest concentration from a little as 1 ppm H2to be detected. Trace gas detection takes place here using aspecially heated sensor technology, which continuously deter-mines the hydrogen concentration in the environment within ameasurement range of 0 to 1,000 ppm H2.

Rising and falling hydrogen concentrations are indicated duringthe measurement by an acoustic indicator in the sensor handleand also by the numerical display of the measured value on thedisplay of the T2000.

In this manner, the user can orientate himself with regard to thehighest H2 concentration either to the acoustic signal or to thedisplayed measured value and thus isolate the leak.

6. Commissioning

6.1. Switching the Sensor System On and OffTo start the system up. you need to connect the three sensorcomponents: T2000 measuring device, TS 800 SDI sensorand BatteryPack with the TC 30 SDI connection cable in the fol-lowing way:

• Connect the TS 800 SDI sensor to the sensor input on theBatteryPack using a TC 30 SDI connection cable.

• Attach the TC 30 SDI connection cable to the SDI socketon the T2000 measuring device (switched off) andconnect the free end on the connection cable to the T2000socket on the BatteryPack.


• We recommend initially switching the BatteryPack to Pos.5 when starting up the sensitivity adjuster on theBatteryPack.

• Switch on the T2000 and make sure that the sensor codefor SDI sensors (S200) is set.

You cannot operate the sensor if the T2000 is not correctly con-nected. If the sensor is only connected to the BatteryPack, andnot to the T2000, the sensor remains deactivated.

Switching off the T2000 disables the sensor system.

The sensor is activated and the sensor start-up phase beginsonce you have performed the activation procedure in line withthe method described above.

6.2. Start-up PhaseThe sensor is now heated to a temperature of approx. 600 °C,independent of the position of the switch chosen on the sensi-tivity adjuster on the BatteryPack. It takes about a minute to heatup the sensor. The unitless display value in the bottom sectionof the display (Sensor 2 Display) displays a countdown valueat the beginning of the heating phase.

During heating up the sensor, the display value sinks towards0 every two seconds for a minute. hence, a quasi numericalcountdown takes place until the sensor is ready for operation.The sensor system is usually ready for operation before 0 isreached.


If the acoustic indicator on the sensor is deactivated, (switch po-sition 6 on the sensitivity adjuster), the end of the heatingphase, i.e., the point when the sensor is ready for operation, issignalised by a short alert tone

If the acoustic indicator is activated (switch positions 1 to 5 onthe sensitivity adjuster), the tone does not sound, because awarning tone sounds automatically at least once a second af-ter the sensor is ready for operation.

The sensor calibrates itself during the heating phase. Thisserves for determining the basic value of the different hydrogenconcentrations determined during the measurement proce-dure. The sensor calibrates itself to the prevailing basic hydro-gen concentration in the ambient air independently during this.

During the heating phase, it is particularly important to ensurethat the sensor is not located close to a relevant hydrogensource.

We therefore recommend performing the start up and heatingin the open or at a location where the hydrogen concentration(< 1 ppm H2) is known to be low.

After the heating phase has come to an end, and self-calibra-tion has takes place, the sensor system is ready for use.

The sensor has now adapted itself to the hydrogen concentra-tion in the environment and both display indicators (Sensor 1and Sensor 2 displays) initially display the basic value.

7. Measured Value DisplayThe TS 800 SDI can identify high resolution hydrogen con-centrations in the recommended measurement range of 0 to1,000 ppm H2.

The T2000 is capable of displaying the hydrogen concentrationsdetermined as unitless digits in a maximum display bandwidthof between 0 and 1,000 digits. The display on the T2000 sup-ports one place behind the decimal point across the completerange of measurement.

Since measurement of the hydrogen concentration in the am-bient air does not take place absolutely, but indicatively de-pending on the basic value, the measured value displayeddoes not necessarily automatically correspond to the ppmvalue!

At the beginning of a measurement run, the basic value is dis-played synchronously on the Sensor 1 display (top displayfield) and the Sensor 2 Display (bottom display field).


The basis value of 0 does not mean that the hydrogen con-centration is 0. It corresponds to the prevailing hydrogen con-centration in the ambient air during the calibration run. This cor-responds to some 0.5 ppm H2 in pure air.

The following illustration shows how this method functions:

Diagrammatic view of measurement ranges and the measured value display

A: Maximum recordable hydrogen concentrations

B: Maximum displayable, absolute measured value range

C: Functional start-up and basic measured value calibrationfor a basic hydrogen concentration of 300 digits

D: Maximum displayable, relative measured value range in standard operating mode

E: Additional, maximum displayable measured value rangewith zero reset

�Important: the correlation of measured value dis-play and H2 concentration is not linear, but loga-

rithmic. The digivalue displayed does not automaticallycorrespond to the ppm value!

8. OperationThe function settings for the sensor are made directly on theBatteryPack. These do not just serve to supply power to thesensor, but also to its control unit.

To this end, the BatteryPack is equipped with a sensitivity ad-juster featuring six different switch positions, and a zero resetkey.


The options for using the sensitivity adjuster and zero resetfunction are described in detail in the following chapters.

In addition, besides the T2000 functions in the bottom menu, thefunctions in the top menu (see T2000 operating instructions)can also be selected directly on the T2000. The functions in thetop menu have not been designed for operating the TS 800 SDI,and are only provided for reasons of development economy.Never use one of the functions in the top menu of theT2000 to operate the TS 800 SDI!

9. Sensor UnitInside the measurement zone, the sensor system displays therising concentration of hydrogen automatically.

Higher concentrations than those relating to the basic value, willbe displayed on both sensor displays along with the corre-sponding digivalues. This takes place synchronously initially.

If you approach an environment with a high concentration of hy-drogen whilst performing a measurement, the value displayedwill rise. If you move away from the area, or if you go into en-vironments where lower concentrations prevail, the value dis-played will fall.

However, it not possible to display measured values below thebasic value, i.e., negative values, in standard operating mode.

The display will also show a minimum of the basic value, if teststake place in areas where hydrogen concentrations below thebasic value prevail.

However, a differentiated indication measurement ispossible with zero reset via the reference value (seeChapter 10)!

Since it can be strenuous keeping an eye on the display of theT2000 to identify the direction of the largest rise in trace gas,an acoustic indicator helps the user. Rising measured valuesresult in a shorter repeat rate and hence the tone soundingmore frequently, so that the changes in values can be very pre-cisely and intuitively detected by using sound without having toread them off the display.

Tone frequency control on the acoustic indicator takes place in-dependent of the switch position on the sensitivity adjuster. Aregular signal tone can be heard, whose frequency also in-creases in parallel to the increase in hydrogen concentration.This means that the tone gets quicker (not louder)

The acoustic indicator is deactivated in switch position 6. Thebasic value (see above) is selected as the relational value for


the signal tone, i.e., the prevailing H2 volume in the ambient airfollowing the sensor setup phase, or alternatively, the referencevalue (See Chapter 10) with differentiated indication measure-ment via zero reset.

The maximum acoustic “peak”, i.e., the quickest signal tonerange reached dependent on the sensitivity adjuster switchposition selected, with different measured value differences(digits), in relation the basic value/reference value:

• Switch position 1: Maximal range at a measured value difference of 500





Therefore, the device first reacts to large quantities of H2 at po-sition 1, and even to very small quantities of H2 at position 5,by emitting a signal tone that steadily increases in loudness.

We therefore recommend that you select switch position 5 withthe largest resolution at the start of a measurement run.

Since the leakage rate and the volume of H2 escaping at theleakage point is still unknown before you start, this enables eventhe smallest leaks to be detected rapidly and reliably, which oth-erwise would not have been detected.

The switch position can be varied at any time during the courseof measurement, according to the discretion of the measure-ment technicians, and adapted to the respective leakage rate.

10. Zero Reset

10.1. Differentiated Indication MeasurementIn standard operating mode, the measured value determined isdisplayed synchronously on both sensor displays. However, itnot possible to display measured values below the basic value,i.e., negative values, in standard operating mode.

The zero reset function is featured for a differentiated indicationmeasurement of this nature.

Determining the measured value with zero reset takes place inrelation to two relational values: the basic value and an addi-tional reference value:


By the pressing the reset button on the BatteryPack, you definethe hydrogen concentration that prevails immediately, i.e., theactual measured value as a new reference value. A short con-firm tone confirms the selection of a new reference value. Twodifferent measured values are shown on the sensor displays atthe same time now.

The top display (Sensor 1 display) continues to take place instandard operating mode, i.e., the measured value determinedand displayed there continues to relate to the basic value.Negative values are still not possible.

The bottom measured value display (Sensor 2 display) now isnow shown relative to the newly set reference value however.This value immediately returns to 0 after pressing the reset but-ton.

When zero reset is used, the sensor reacts to the smallestchange in H2 concentration even when increased H2 concen-tration prevails in the environment.

If you now enter environments with higher or lower hydrogenconcentrations, the measured value shown in the bottom meas-ured value display changes in relation to the reference value.It rises when hydrogen concentrations increase. If the hydrogenconcentrations fall, only negative values in relation to the ref-erence value are shown.

What is more, the basic value no longer serves as a referencevalue for the signal tone ranges, but the reference value se-lected (see Chapter 9).

The combination of the top measured value display, in relationto the basic value, and the bottom measured value display, in re-lation to the reference value, even permits precise localisationof the H2 escape point in environments lightly enriched in H2 inunfavourable conditions, when a systematic approach is used.

10.2. Diagrammatic Example of the MeasuredValue Displays

Three fictional measurement environments bordering ion oneanother are used as a basis in diagram featured below:

In Environment 1 a basic hydrogen concentration corresponding to 200 digits prevails.



The basic hydrogen concentrations are not known to the ex-ample user, but are given so that the user can achieve betterunderstanding.


The sensor system is started up in Environment 1. Following thestart-up phase and auto-calibration, Basic Value 0 is specifiedcorrespondingly for a prevailing hydrogen concentration corre-sponding to 200 digits.

Measurements initially take place in standard operatingmode:

Hence, in Environment 1, the relative measurement value of 0is displayed synchronously in the top and bottom measuredvalue display.

The user now comes to Environment 2. Both measured valuedisplays show a relative measurement value of 100 in relationto the basic value.

Finally, the user comes to Environment 3. Both displays show0 here, although the basic hydrogen concentration is 100 dig-its lower than the concentration based on the basic value.

For reason for this is that is it not possible to display measuredvalues below the basic value, i.e., negative values, in standardoperating mode. This user now returns to Environment 1 to usezero reset.

Additional use of zero reset:

This user finds himself back in Environment 1. He activates zeroreset and defines an additional reference value for the currentenvironment concentration.

The top display now shows the measured value relative to thebasic value and the bottom display show the measured valuerelative to the reference value. Since both the determination ofthe basic value and also the one for the reference value tookplace in this environment, both measured value displays in thisenvironment initially show a value of 0.

The user now returns to Environment 3. The top display showsa measured value of 0 in relation to the basic value here, butthe bottom display shows a measured value of -100 in relationto the reference value.

Still in Environment 3, the user performs another zero reset. Themeasured value display for the reference value now changesfrom -100 to 0, since this environment has been determined asthe new reference value. Following this the user enters Envi-ronment 2. Here, the display shows a measured value of 100as in the beginning, since the basic value has not beenchanged. Due to the renewed zero reset in Environment 3, andas a result of the reference value being redetermined, the bot-tom measured value display in Environment 2 now shows ameasured value of 200 however.

�Important: The correlation of the measured value display and H2 concentration is not linear,

but logarithmic. The digivalue displayed does not auto-matically correspond to the ppm value!

10.3. Example in practice:The measuring point is located in the basement of a house. Apressure water line was identified as the element to be testedthrough previously performed pressure checks, and the lineruns through a total of three basement rooms, none of whichhave a window.

After purging the line with air using a compressor and then introducing the testing gas, the gas now escapes at the leak-age point. The location needs to the found. Since no dampspots can be found on the floor, each room needs to bechecked individually.

The first measurement takes place in basement room 1 withoutsuccess. After approx. Unsuccessful measurement also takesplace in basement room 2 for five minutes. The leak musttherefore be located in basement room 3.


After 10 minutes, the person performing the measurements en-ters the third basement room, which is now full of gas. The de-vice display a high basic peak and lets out signal tones at a highfrequency.

Since the room cannot be aired, the leak needs to be found withthe prevailing high concentration of H2. We recommend the fol-lowing method for this:

Activate a reference value by pressing zero reset (see above)

Active replication is carried out by the uses in relation to the H2environment concentration here. This is now taken as being ref-erence value 0.

The device now reacts to concentrations that are rising up-wards, such as directly above or close to the leak, with corre-sponding tone and/or number peaks.

Even the function of the sensitivity adjuster with its six settingoptions is completely retained.

This method hence enables the localisation of high H2 con-centrations, even in environments that are highly enriched withtest gas.

11. Acoustic and Optical SignalsBesides the messages described in Chapter 6.2., other opticaland audible messages may be given out during start-up and op-eration:

Switching on the device1. BatteryPack is flat:

A warning tone sounds three times, and repeats every 10 seconds: the top display flashes showing “-1000.0”(battery voltage < 11 V).

The sensor system cannot be used in this state. The Battery-Pack needs to be charged up first or you can use the sensor byconnecting the charger. You need perform a reset or switch thedevice off to reset the status.

2. BatteryPack is in reserve with 11.5 and 11 V: Two shortwarning tones, the system starts as normal otherwise.

3. Sensor has a short circuit/Sensor defective:A warning tone sounds; bottom display shows “-1.0”continuously.


Operation4. BatteryPack voltage falls below the 11 V threshold during

a measurement:A warning tone sounds three times, and repeats every 10 seconds: the top display flashes showing “-1000.0”(battery voltage < 11 V).

Operation is terminated to prevent damage to the battery. TheBatteryPack needs to be charged up first or you can use thesensor by connecting the charger.

You need perform a reset or switch the device off to reset thestatus.

12. Information on the BatteryPackEach BatteryPack is equipped with a special lead battery,which permits working continuously for 4 hours.

If possible, the battery should always be charged up fully, andthen discharged as fully as possible.

This ensures high long-term battery capacity and hence corre-spondingly high performance.

If the battery is not completely discharged occasionally, what isreferred to as the "memory effect" occurs the next time it is

recharged. This is why intermediate charge ups should beavoided if possible.

If the battery starts to flatten during measurement, operation isterminated automatically to protect the battery.

In cases like this, the TS 800 SDI can be operated directly overthe charger connected to the BatteryPack, insofar as the bat-tery is not completely flat and a minimum voltage is available.

Some of the line current can be used to operate the sensor inthis manner, and some to charge up the battery.

Before your attempt this, make sure you check that thebattery is not completely flat!

� Important: always store and charge the battery at a temperature of 15 °C - 35 °C, otherwise

extreme losses in capacity and even damage to the battery can take place in the long-term!


13. Disruptive Influences

No direct H2 sources during the start-up:Never bring the TS 800 SDI into direct contact or the direct prox-imity of a hydrogen source during the start-up phase, since thiswill influence calibration of the basic value for the sensor andhence its corresponding sensitivity to H2!

Ambient noise on the sensor:If the sensor is addressed over switch positions 5 or 6 on thesensitivity adjuster, the measured value displayed can rise tobetween approx. 20 and 30 digits for a long period of time dueto the sensor characteristics.

This ambient noise is normal and can be ignored across thewhole measurement range of 1,000 digits.

Transverse sensitivity:The TS 800 SDI features transverse sensitivity to flammablegases such as alcohol-air mixes, methane and hydrocarbons.

This transverse sensitivity is based on the physical principle ofthe detection procedure and applies to nearly all devices avail-able on the market.

An increase in the warning tone does no necessarily mean thedetection of H2, but can also mean that flammable gases towhich the sensor can react have been detected.

We therefore recommend carefully inspecting these locationsfor anything conspicuous and consider whether they can in anyway be brought logically into connection with the leak to be lo-calised.

If, in individual cases, a large, permanent source of distur-bance is the cause, and localisation takes place in precisely thisenvironment, zero reset should be used for the actual meas-urement (See Chapter 10).

This reduces sensitivity to the source of the disturbance and thesensitivity to the H2 to be localised is increased correspondingly.


14. CleaningYou should only clean the silver-coloured protective sensor cap(sinter filter) designed to protect the sensor technology.

The cap is completely sealed with a special sticker since dam-age to the sensor (and burns!) may otherwise occur.

If the sinter filter is dirty, it can be cleaned by lightly putting pres-sure on it with what is known as a file brush. This is a brush withvery short bristles frequently used for cleaning metal files of fil-ings.

To clean it, the protective sensor cap must be tightly screwedshut, so that fine dust does not enter the sensor element underthe cap.

You can also clean fine dust off the sinter filter by using com-pressed air. To do this, you should make sure that the air is onlydirected as the silver-coloured protective sensor cap.

Always clean the cap when the system is switched off and hascooled down. This takes about five minutes after the system hasbeen switched off.

Never use water or aggressive cleaning agents. These maycome into contact with the sensor head and damage it.

15. Practical TipWe recommend using a MultiMeasure Extension Arm whenyou stand to work or need to work along long line lengths.

If you do use the TS 800 SDI in combination with the Multi-Measure Extension Arm, we also recommend lengtheningthe sensor-side TC 30 SDI connection cable with another TC 30 SDI cable to double its effective length.

If you bend the semi-flexible sensor neck, you can reach andcheck otherwise inaccessible fitting components.

In principle, we recommend having two BatteryPacks foreach TS 800 SDI unit, so you can still use the system if thefirst battery is flat and no electricity is available.
