[SENSe:]TEMPerature:TRANsducer:TCouple:CHECk {ON|1|OFF|0}
[SENSe:]TEMPerature:TRANsducer:TCouple:CHECk?
Disables or enables the
thermocouple check
feature to verify that your thermocouples are properly con-
nected for measurements. When enabled, the instrument measures the resistance after each ther-
mocouple measurement to ensure a proper connection. If an open connection is detected (greater than
5 kΩ on the 10 kΩ range), the instrument reports an overload condition.
Parameter
Typical Return
{ON|1|OFF|0}. Default: OFF.
0 (OFF) or 1 (ON)
Configure K-type thermocouple measurements. Select fixed reference junction and set reference junction
temperature to +20 °C. Enable thermocouple check. Make and read two measurements:
CONF:TEMP TC,K
TEMP:TRAN:TC:RJUN:TYPE FIX
TEMP:TRAN:TC:RJUN 20.0
TEMP:TRAN:TC:CHEC ON
SAMP:COUN 2
READ?
Typical Response: +3.3100,+3.6100
l
Applies only to the 34465A and 34470A.
l
Enabling the thermocouple check feature slows measurement rates because two measurements have
to be made for each temperature measurement values produced.
l
This parameter is set to its default value after a Factory Reset (
) or Instrument Preset
(
).
