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 278.
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.
