6.4.3 Measuring temperature
6.4.3.1 Using thermocouples
The calibrator supports the following types of
thermocouples: B, C, E, J, K, L, N, R, S, T, U, BP and
XK. The typical characteristics of all of these types
are described in chapter 10 “Specifications”. The
calibrator also has a “CJC” (cold junction compensation) function. In normal operation, the function
will be activated, and it will measure the effective
temperature of the thermocouple. If the option
“CJC” is deactivated, the calibrator measures the
difference between the thermocouple at the connection point and the input terminal of the
thermocouple.
The CJC option should only be deactivated when the calibration is being
made with an external ice bath.
To measure temperature with the thermocouple, follow the steps below:
1. Connect the wires of the thermocouple to the input/output of the calibrator using the
thermocouple mini-connector (see following figure).
The connecting cable for the thermocouple must match the type of the
thermocouple being calibrated.
2. In the main menu, switch to the lower display “LOWER” and select “TC”.
3. The input/output setting must be set to “IN”.
4. Select the corresponding thermocouple type in the menu.
5. Select temperature unit.
In the interests of optimum accuracy, wait 2 to 5 minutes so that the
temperature between the mini-connector and the calibrator stabilises.
After this, carry out the measurement.
The calibrator can measure the voltage of the thermocouple in mV, so that the temperature can be determined with the aid of a table if the corresponding thermocouple type is
not supported by the calibrator. For the case described above, proceed and select “mV”
as the type.

6.4.3.2 Using resistance thermometers (RTDs)
The supported resistance thermometers are detailed in the specifications in chapter
10 “Specifications”. The specific characteristic of RTDs is their temperature-dependent
resistance (R0). The calibrator can work with input signals with 2-, 3- or 4-wires, where
input measurements with 4-wire connection are the most accurate.
To measure temperature with resistance thermometers, follow the steps below:
1. In the main menu, switch to the lower display “LOWER” and select “RTD”.
2. The input/output setting must be set to “IN”.
3. Select 2-, 3- or 4-wire connection “2W, 3W, 4W”.
4. Select the corresponding RTD type in the menu.
5. Select temperature unit.

6.4.4 Measuring pressure
CAUTION!
Pressurisation
Damage within the pressure system due to open valves.
1. Close the valve.
2. Release the pressure slowly.
3. Connect the pressure module to the pressure line.
ATTENTION!
Damage to the threaded connections
The pressure module can be damaged by over-tightening the threaded
connection.
▶
Use suitable tools.
▶
Tighten the pressure connection with a maximum of 13.6 Nm (torque
spanner).
▶
Never exceed the permissible maximum pressure.
▶
Only use pressure modules with compatible media. See specification of
the pressure module.
To measure pressure with external pressure modules, follow the steps below:
1. Connect the pressure module to the calibrator using the pressure module adapter (see
following figure).
For the connection of the pressure module to the calibrator, a WIKA
pressure module adapter must be used.
2. From the main menu, switch to the upper or lower display as required. The calibrator
measures pressure in the upper as well as the lower display. In this way, pressure can
be measured on two different units at the same time.
3. As the primary parameter, select “PRESSURE”.
4. Select the desired unit of measure.

With high-pressure modules, technical units of measure that are only
used for low pressure ranges, such as inH
2
O, cmH2O, etc., are not valid
selections. If one of these units is selected with a high-pressure module
connected, “----” is shown on the display.
5. Set the pressure module to zero (ZERO). The function to reset the calibrator is found
under the “ZERO” menu function.
6.4.4.1 Zeroing of absolute pressure modules
To reset the calibrator to zero, set it so that it measures a known pressure, for example the
barometric pressure.
To zero the calibrator, follow the steps below:
1. Call up the menu function “ZERO”.
2. Select “ZERO”. “SET REFERENCE ABOVE” will
be displayed.
3. Enter the reference pressure via the keypad.
The calibrator saves the barometric reference value
in permanent memory. The reference value will
always be saved for an absolute pressure module. If
a new absolute pressure module is connected, this
procedure must be repeated.
