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.
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.
