RTD Measurements
• The meter supports RTDs with α = 0.00385 (DIN/IEC 751) or
α = 0.00391. The nominal value of the RTD (R
0
) must be in the range
of 4.9 Ω to 2.1 kΩ. 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
0
) in the 4: RTD R
0
command
in the TEMPerature menu.
• Remote operation: Use the following commands for temperature
measurements with RTD’s:
CONFigure:TEMPerature FRTD,{85|91}[,1,<
resolution
>]
MEASure:TEMPerature? FRTD, {85|91}[,1,<
resolution
>]
SENSe:FUNCtion "TEMPerature"

SENSe:TEMPerature:TRANsducer:FRTD:TYPE {85|91}
SENSe:TEMPerature:TRANsducer:FRTD:RESistance <

Thermistor Measurements
• Only the 5 kΩ 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 THER, DEF,[,1,<
resolution
>]
MEASure:TEMPerature? THER, DEF,[,1,<
resolution
>]
SENSe:FUNCtion "TEMPerature"
SENSe:TEMPerature:TRANsducer:TYPE THER
