Temperature Measurement Configuration
This section contains information to help you configure the instrument
for making temperature measurements. For more information on the
types of temperature transducers, see “Temperature Measurements”
starting on page 267.
The instrument supports direct measurement of thermocouples, RTDs,
and thermistors. The instrument supports the following specific types of
transducers in each category:
Measurement Units
• The instrument can report temperature measurements in
°C (Celsius), °F (Fahrenheit), or K (Kelvin). You can mix temperature
units on different channels within the instrument and on the same
module.
• 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.
• Setting the Mx+B measurement label to °C, °F, or K has no effect on
the temperature measurement units currently selected.
• Front-Panel Operation: First, select the temperature function on the
active channel. Then, select the temperature units.
