Temperature Measurement Configuration

RTD Measurements

The meter supports RTDs with
= 0.00391. The nominal value of the RTD (R
of 4.9 to 2.1 k . RTD Connections are shown on page 21.
The meter makes a 4-wire measurement for RTD's. All four input
leads must be connected.
Front Panel operation: Set RTD as the probe type under the
1: PROBE TYPE command in the TEMPerature menu.
Select the RTD type under the 3: RTD TYPE command in the
TEMPerature menu.
Enter the 0° C resistance of the RTD (R
in the TEMPerature menu.
Remote operation: Use the following commands for temperature
measurements with RTD's:
CONFigure:TEMPerature
MEASure:TEMPerature?
SENSe:FUNCtion "TEMPerature"
SENSe:TEMPerature:TRANsducer:TYPE
SENSe:TEMPerature:TRANsducer:FRTD:TYPE
SENSe:TEMPerature:TRANsducer:FRTD:RESistance

Thermistor Measurements

Only the 5 k thermistor type is supported. Thermistor connections
are shown on page 21.
The thermistor must be connected to the Channel 1 inputs.
Front Panel operation: Set THERM as the transducer type under
the 1: PROBE TYPE command in the TEMPerature menu.
Remote operation: use the following commands for temperature
measurements with a thermistor:
CONFigure:TEMPerature
MEASure:TEMPerature?
SENSe:FUNCtion "TEMPerature"
