The
<

parameter specifies the sensor type that will be used to
determine the temperature of the isothermal reference panel.
<

CUSTom
is pre-defined as Type E with 0
°
C reference junction temperature, and is
not re-defineable. The user is responsible for providing an E type thermocouple
with 0
°
C reference junction.

The
*CAL?
command calibrates resistance channels based on Current Source SCP
and Sense Amplifier SCP setup at the time of execution. If SCP settings are
changed, those channels are no longer calibrated.
*CAL?
must be executed again.
•
This command will cause Error +3000, “ illegal while initiated” if trigger is initiated.

Usage
Sense the reference temperature on channel 20 using an RTD.
SENS:REF RTD,92,(@120)
[SENSe:]REFerence:TEMPerature
[SENSe:]REFerence:TEMPerature <
degrees_c
>
stores a fixed reference junction
temperature in the Reference Temperature Register. Use when the thermocouple
reference junction is kept at a controlled temperature.
Note
This reference temperature is used to compensate all subsequent thermocouple
measurements until the register is overwritten by another
SENSe:REFerence:TEMPerature
value or by scanning a channel linked with the
SENSe:REFerence
command. If used,
SENSe:REFerence:TEMPerature
must be
executed before scanning any thermocouple channels.
