Setting function parameters
Some measurement functions have additional parameters. When measuring the temperature using RTD sensors,
R0 (resistance at 0
C) can be set, when measuring the temperature using TC sensors, the temperature of cold
junction can be set and when measuring using SGS sensors, supply voltage of the bridge can be set.
Original settings are listed below:
T RTD
R0 = 100
T TC
RJ =23 °C
SGS
Voltage = 5 V
The parameters can be changed as follows:
•
