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
EN
XK. The typical characteristics of all of these types
are described in chapter 10 "Specifications". The
calibrator also has a "CJC" (cold junction compen-
sation) 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.
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).
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.
The calibrator can measure the voltage of the thermocouple in mV, so that the tempera-
ture 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.

The CJC option should only be deactivated when the calibration is being
made with an external ice bath.
The connecting cable for the thermocouple must match the type of the
thermocouple being calibrated.
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.
