[SENSe:]TEMPerature:[TRANsducer:]<subfunction>:TYPe(?) <n>
Description Sets the RTD type for the temperature function. This setting is stored in
volatile memory.
Parameters <subfunction> = RTD 2-wire RTD
FRTD 4-wire RTD
<n> = PT100_385 Sets the RTD type to PT100 385 (R0 to
100Ω and Alpha to 0.00385055)
PT100_392 Sets the RTD type to PT100 392 (R0 to
100Ω and Alpha to 0.00391600
CUST1 Sets the RTD type to be set by R0 and Alpha
settings.
Examples TEMP:RTD:TYP PT100_385 Sets the RTD type to PT100 385.
Query TEMP:RTD:TYP? Returns 385 or CUSTOM.
[SENSe:]TEMPerature:[TRANsducer:]<subfunction>:ALPHa(?) <n>
Description Sets the alpha variable for the temperature function. This setting is stored
in volatile memory.
Parameters <subfunction> = RTD 2-wire RTD
FRTD 4-wire RTD
<n> = .00374 to .00393 Sets the alpha parameter
Examples TEMP:RTD:ALPH 0.00392 Sets the alpha parameter to 0.00392.
Query TEMP:RTD:ALPH? Returns the alpha setting of the temperature
function.
[SENSe:]FREQuency:APERature(?) <n>
Description Sets the gate time for the frequency function to the value specified by <n>.
This setting is stored in volatile memory.
Parameters <n> = 0.01 Gate time of 10 ms (4½ digits)
0.1 (default) Gate time of 100 ms (5½ digits)
1 Gate time of 1 second (6½ digits)
MIN Gate time of 10 ms (4½ digits)
MAX Gate time of 1 second (6½ digits)
Examples FREQ:APER 0.1 Sets the frequency measurement gate time to 100
ms.
Query FREQ:APER? Returns the gate time for the frequency function.
[SENSe:]PERiod:APERature(?) <n>
Description Sets the gate time for the period function to the value specified by <n>.
This setting is stored in volatile memory.
Parameters <n> = 0.01 Gate time of 10 ms (4½ digits)
0.1 (default) Gate time of 100 ms (5½ digits)
1 Gate time of 1 second (6½ digits)
MIN Gate time of 10 ms (4½ digits)
MAX Gate time of 1 second (6½ digits)
