Query
:CURRent? Query sensor current
Description
This command programs the temperature sensor (transducer) excitation
current. It affects only thermistor and RTD sensor types. Nominal sen-
sor currents are: 3.3e-6, 1e-5, 3.33e-5, 1e-4, 8.333e-4, and 2.5e-3.
:AUTO <b>
[:SENSe[1]]:RESistance:CURRent:AUTO <b> Enable/disable auto sensor current
Parameters
<b> = 1 or ON Enable auto sensor current
0 or OFF Disable auto sensor current
Query
:AUTO? Query auto sensor current state
Description
This command enables or disables the auto sensor current mode. When
the auto current mode is enabled, the sensor current is set as follows:
Range Current
100

:TRANsducer <name>
[:SENSe[1]]:RESistance:TRANsducer <name> Select resistance temperature sensor
Parameters
<name> = THERmistor Select thermistor sensor
RTD Select RTD sensor
Query
:TRANsducer? Query sensor type
Description
This command selects the temperature sensor for the resistance func-
tion. Only thermistor and RTD sensor types are available for the resis-
tance function.
