3.3 Measuring Temperature

3.3-1 Using Thermocouples

The calibrator supports the followingthermocouple types: B, C, E, J, K, L,N, R, S, T, U, BP, and XK. Thecharacteristics of all the types aredescribed in Specifications section.The calibrator also has a ColdJunction Compensation (CJC)function. Normally this function should be ON and the actual temperature ofthe thermocouple will be measured. With CJC OFF, the calibrator willmeasure the difference between the thermocouple at the junction and at itsTC input terminal.

Note: CJC off mode should only be used when calibration is being doneusing an external ice bath.

To use the thermocouple to measure temperature, follow these steps:

1. Attach the thermocouple leads to the TC miniplug, and insert the pluginto the input/output of the calibrator, as in Figure 7.

Note: For best accuracy wait 2 to 5 minutes for the temperature betweenthe miniplug and the calibrator to stabilize before any measurements aretaken.

2. Switch to lower display from Main Menu.

3. Select TC from the primary parameters. Choose [IN] in the input/outputcontrol, and than the thermocouple type from the sensor types. Thetemperature unit may also be changed from Celsius to Fahrenheit.

The calibrator can also measure the mV of a Thermocouple, which can beused along with a table in case the corresponding TC type is not supportedby the calibrator. To do so, proceed as above and choose mV from sensortypes.

3.3-2 Using Resistance-Temperature-Detectors (RTDs)

The supported types of RTDs are shown in Section 8. Specifications.RTDs are characterized by their 0°C resistance, R0. The calibratoraccepts two, three, and four wire inputs, with four wire input being themost accurate.

To use the RTD option, apply the following steps:

1. Switch to lower display [LOWER] from Main Menu.

2. Select RTD from the primary parameters. Select [IN] frominput/output control.

3. Choose 2, 3, or 4-wire connection [2W, 3W, 4W]. (4-wire allows forthe most precise measurement)

4. Select RTD type from the sensor types.

5. Attach RTD leads as shown in Figure 8.

Figure 8. Measuring Temperature with RTD Connection

Resistance can also be measured using this function. To do so, use theabove procedure and choose OHMS from the sensor types. This optioncan be used along with a table to measure an RTD which is notprogrammed into the calibrator.

3.4 Measuring Pressure

CautionTo avoid mechanically damaging the pressure module, never apply more than13.5 Nm/10 ftlbs. of torque between the pressure module fittings, or betweenthe fittings an the body of the module.

To avoid damaging the pressure module from overpressure, never applypressure above the rated maximum printed on the module.

To avoid damaging the pressure module from corrosion, use it only withspecified materials. Refer to the pressure module documentation for materialcompatibility.

To measure pressure, follow these steps:

1. Connect the pressure module to the calibrator as shown in Figure 9.

The calibrator can measure pressure on both the upper and the lowerdisplay. This makes it possible to measure pressure in two different unitsat the same time.

2. Switch to either upper or lower display from the Main Menu.

3. Select [PRESSURE] from the primary parameters.

4. Select the desired measuring unit.

5. Zero the pressure module. The zero function on the calibrator can befound in the pressure zeroing menu.
