1.11.1 Initial set-up
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.
1.11.2 Temperature configuration
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 '1º' for 1º resolution or select
'0.1º' 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'.
