Temperature Measurement Configuration

This section contains information to help you configure the instrument for making temperature measurements. The table below shows the thermocouple, RTD, and thermistor types for which the instrument supports direct measurements.

Temperature transducers supported

Thermocouple Types*	RTD Types	Thermistor Types
B, E, J, K, N, R, S, T	R0 = 49Ω to 2.1 kΩ	2.2 kΩ, 5 kΩ, 10 kΩ
	α = 0.00385 (DIN/IEC 751) *	(YSI 44000 Series)

α= 0.00391 †

*Using ITS-90 software conversions.

† Using IPTS-68 software conversions.

Measurement Units

•The instrument can report temperature measurements in °C (Celsius), °F (Fahrenheit), or K (Kelvins). You can mix temperature units on different channels within the instrument and on the same module.

•The CONFigure and MEASure? commands automatically select °C.

•Setting the Mx+B measurement label to °C, °F, or K has no affect on the temperature measurement units currently selected.

•The instrument selects Celsius when the probe type is changed and after a Factory Reset (*RST command). An Instrument Preset (SYSTem:PRESet command) or Card Reset (SYSTem:CPON command) does not change the units setting.

Front Panel Operation: DMM or Channel (Configure) > TEMPERATURE > UNITS

Remote Interface Operation: UNIT:TEMP {CFK}[,(@<ch_list>)]
