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 effect 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.
