RTD Commands

[SENSe:]TEMPerature:TRANsducer :RTD:TYPE {8591}[,(@<xt >)] :RTD:TYPE? [(@<xt >)]

:FRTD:TYPE {8591}[,(@<x >)] :FRTD:TYPE? [(@<xt >)]

Select the RTD type for 2-wire or 4-wire measurements on the specified channels. Use “85” to specify α = 0.00385 or “91” to specify α = 0.00391. The default is “85”. The :TYPE? query returns the RTD type in use on the specified channels. Returns “+85” or “+91”.

[SENSe:]TEMPerature:TRANsducer
:RTD:RESistance[:REFerence] <xz	>[,(@<xt	>)]
:RTD:RESistance[:REFerence]? [(@<x	>)]
:FRTD:RESistance[:REFerence] <“zxz	>[,(@<xt	>)]

:FRTD:RESistance[:REFerence]? [(@<xt >)]

Set the nominal resistance (R0) for RTD measurements on the specified channels. Select a value between 49Ω and 2.1 kΩ. The default is 100Ω. The :REF? query returns the nominal resistance (R0) in use on the specified channels. Returns a number in the form “+1.00000000E+02”.

Thermistor Commands
[SENSe:]TEMPerature:TRANsducer
:THERmistor:TYPE {2252500010000}[,(@<x		>)]
:THERmistor:TYPE? [(@<x	>)]

Select the thermistor type for measurements on the specified channels. The default is a 5 kΩ thermistor. The :TYPE? query returns the thermistor type in use on the specified channels. Returns “2252”, “5000”, or “10000”.
