- Press
“P1/P2” to choose between P1, P2 and P1-P2.
5.1.2 Temperature
- Press
“Units▼“ to choose the correct temperature scale.
- Press
“T1/T2” to choose between T1, T2 and T1-T2 values.
ATTENTION:
The display will show “- - - -“ if the thermocouple is not installed. The display will
show “OL” (overload) if the measured temperature is out of the measurement range of the
thermocouple.
5.2 Further functions

Use the offset function to adjust the measurement value and compensate for measurement
errors of the thermocouple. The permitted deviation for thermocouples is ±5 °C.
- Connect the thermocouple to the input socket.
- Place the thermocouple in a known and stable environment (like a calibrator).
- Wait until the value is stable.
- The settings menu allows you to adjust the offset until the primary value equals the
calibration value.
