The ‘ Temperature configuration ’ (‘ cnF.t ’) menu allows to configure
several functions associated to the measure and working with tem -
perature signals.
• at the ‘ Degree ’ (‘ dEG ’) menu, select ‘ ºc ’ to measure in Celsius
degrees, or select ‘ ºF ’ to measure in Fahrenheit degrees.
• at the ‘ Resolution Pt100 ’ (‘ P.rES ’) menu, select the reading res -
olution for the Pt100 / RTD. Select ‘1 º ’ for 1º resolution or select
‘0.1 º ’ for 0.1º resolution.
• at the ‘ Reading offset ’ (‘ oFFS ’) menu, configure a number of
counts to be added to the reading. Applies both to the measure in
Pt100 / RTD and thermocouples. This offset allows to correct read -
ing errors associated to different types of probes, which can not
be corrected by other means. Offset value allows for ‘±100’ display
counts.
• the ‘ Thermocouple CJC ’ (‘ t.cJc ’) menu allows to active or deacti -
vate the automatic compensation of the thermocouple cold junc -
tion. When working with a real thermocouple, compensation must
be on. In case of using an electronic thermocouple simulator, it may
be needed to deactivate the automatic cold junction compensation.
• at the ‘
on break ’ (‘ on.bk ’) menu select the behavior of the instru -
ment in case of sensor break detection. Select ‘ to_h ’ to set reading
to overrange, or select ‘ to_L ’ to set reading to underrange.
• at the ‘ Alpha ’ (‘ ALPh ’) menu configure the alpha for the
Pt100 / RTD. The standard values in industry are ‘ 385 ’ and ‘ 390 ’.

To configure the initial set up of the instrument, select the type of
sensor to be connected to the instrument.
Access the ‘
Input ’ (‘ InP ’) menu to select the type of sensor. Options
available are Pt100 / RTD with 2 and 3 wires, and thermocouples J, K,
T, E, S, R, N, C, L and X. Thermocouple X is a linear signal os 10 uV/ºC.
