[SENSe:]TEMPerature:TRANsducer:TCouple:CHECk {OFF | ON} [, (@<ch_list>)]
[SENSe:]TEMPerature:TRANsducer:TCouple:CHECk? [(@<ch_list>)]
Only supported in DAQM900A, DAQM901A, and DAQM902A multiplexer modules.
This command is not supported in DMM Digitize data acquisition mode.
Error -221,"Settings conflict; DMM digitizing mode has been disabled" will be generated when you send the
command to enable open detect check for thermocouple temperature measurement in DMM Digitize mode.
Enables or disables the thermocouple check feature to verify that your thermocouples are properly connected for
measurements. When enabled, the instrument measures the resistance after each thermocouple measurement to
ensure a proper connection. If an open connection is detected (greater than 5 kΩ on the 10 kΩ range), the instru-
ment reports an overload condition.
Parameter Typical return
{OFF | ON}. Default: OFF 0 (OFF) or 1 (ON)
Enables the thermocouple check feature: TEMP:TRAN:TC:CHECKON
– Enabling the thermocouple check feature slows measurement rates because two measurements have to be
made for each temperature measurement values produced.
– This parameter is set to its default value after a Factory Reset (*RST command).
[SENSe:]TEMPerature:TRANsducer:TCouple:RJUNction {<temperature> | MIN | MAX | DEF}
[, (@<ch_list>)]
[SENSe:]TEMPerature:TRANsducer:TCouple:RJUNction? [{(@<ch_list>) | MIN | MAX | DEF}]
Only supported in DAQM900A, DAQM901A, and DAQM902A multiplexer modules.
Sets the fixed reference junction temperature in degrees Celsius (°C) for thermocouple measurements on the spe-
cified channels.
Parameter Typical return
<temperature>: A number representing the temperature
from -20 °C to +80 °C
Default: 0 °C
+1.12345678E+01
Sets the fixed junction temperature in degrees Celsius for thermocouple measurements:
TEMPerature:TRANsducer:TCouple:RJUNction 27.3
Typical response: 2.73000000E+01
– For this command, you must always specify the temperature in degrees Celsius regardless of the temperature
units currently selected (see UNIT:TEMPerature command).
– This parameter is set to its default value after a Factory Reset (*RST command).
