Selecting the INT RJ Function
The INT RJ function provides reference junction compensation for
thermoelectromotive force source in a simplified manner by means of
the calibrator's built-in temperature sensor. For more precise refer-
ence junction compensation, it is advisable that you use the optional RJ
sensor (P/N: B9108WA).
Step 1: Press the
key to turn off the calibrator.
Step 2: Place switch 3 (INT RJ switch) in the ON (right-side) position.
The calibrator detects temperature using its built-in tempera-
ture sensor and outputs reference junction-compensated
thermoelectromotive force appropriate for the detected tem-
perature.
Step 3: To disable the INT RJ function, turn off the calibrator by
pressing the
key.
Step 4: Place switch 3 back in the OFF (left-side) position.
TIP
Even when the INT RJ function is selected, the temperature detected by an external
RJ sensor precedes any other measured temperature if you plug the sensor into the
RJ INPUT connector.

Selecting the IPTS-68 Function
By placing switch 4 (IPTS-68 switch) in the ON (right-side) position, you
can select the IPTS-68 temperature scale when you choose the type-K,
E, J, T, N, R, S or B thermocouple or the Pt100 RTD. Placing the
switch in the OFF position results in the selection of the ITS-90 tem-
perature scale.
TIP
When you have selected a type of thermocouple or RTD, the LCD shows IPTS-68.
