liquid is by anlog, low voltages with ver high imce levels. Therefore,disturbing influences mut be rninsed.Before coiiectig sensor cales to the anyser inpit the following cotions mutbe considered:- the senr cales are (preferably) not roted in trck together with high pocales an cales with signls of switched high voltage or high. energy;

- the stada sensor cables are used;- the anyser is mounted as nea as posible to the senrs (short senr cales).

The 2nd buffer solution is for calibrationof the seni ti vi ty of the electrodes (slope)and usually, a buffer solution of 4 pH is coosen.This solution has a high staility.

for entering the inputs of electrode chaacteristics only (pagraph 5-2-1-3).24

5-3-4. Calibration (or sta) moe.In ths moe buffer solution calibration is pefonn using the key "STANAR"

(see paagraph 5-2-1-1 ). Next to the 'I0 anlyzer ths calibtion reqires a pairof eleces an bufer solutions of which the pH value is Ja (accucy 0,01 pH)as a function of tentue.5-3-4-1. Flow cha.

Before stag the prce, san remksnnt be made:1. The 'l0 anlyzer measues the voltage outpt

of the pair of el-et.e5 an caes it withthe theoretical value of the pro: bufersolutions when ideal elect.es are used.

2. The 'l0 anlyzer indicates the pH value atreference temabie (25°C) an the opeatornnt cae it with the value on the box orbottle of the bufer solution.If the inicated value differs fra the actlvalue, then the operator ca call anotherbufer solution by activatig the key "NE"until the correc bufer solution value isinicated.ru: An incorrect inication of the bufer

solution is often caused by:- old buffer solution- high asyretr voltage of the pair of

elect.es- dirty electrodes- residue of old buffer solutions mied'with the actul ones.

Therefore it is likely tht the anlyzerwill not accept the pefonn calibrationan an err message will be indicated.Activate IlREII an repet calibationafter cleaing the electres thoroughlyan prepaing new bufer solutions.

3. The pH value of 5 buffer solutions (to NBstad) are stored in the anlyzer as afunction of temrature. If a temratuecator is used during calibtion, theanlyzer recses the value easily. However,if maual temrabie cction is appliedthe actl tematue nnt be entered in the'I0 maually.

4. D.ing caibration the anlyzer is in themaintence moe. Maintence contact is closedan mA outpt is "HOW".

Prepation.Nessa eq pnt:1. 3 vessels of 200 ml, e.g. plastic calibation

dishes as supplied with the flow fittings.2. Bufer ¡:wders, talets or "ready to use"

buffer solution according to NB stadad.3. Deinerlised water to prepae solutions

an to flush the sensors.4. Thereter if no tematue ccpetor is
