Keithley 3700 Series User Manual

Section 11: TSP command reference Series 3700A System Switch/Multimeter Reference Manual
11-222 3700AS-901-01 Rev. D/June 2018
An error is generated if the value is out of range.
Example 1
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THREERTD
dmm.rtdbeta = 0.3
dmm.transducer = dmm.TEMP_FOURRTD
dmm.rtdbeta = 0.5
dmm.transducer = dmm.TEMP_THREERTD
print(dmm.rtdbeta)
Set a beta constant for RTD to 0.3 for 3-wire
RTD.
Change to 4-wire RTD.
Change the beta constant to 0.5.
Switch back to 3-wire RTD. The value is 0.5.
Output:
5.000000000e-01
Example 2
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THREERTD
dmm.rtdbeta = 0.3
dmm.configure.set("RTD_3wire")
dmm.transducer = dmm.TEMP_FOURRTD
dmm.rtdbeta = 0.5
dmm.configure.set("RTD_4wire")
dmm.configure.recall("RTD_3wire")
print(dmm.transducer, dmm.rtdbeta)
dmm.configure.recall("RTD_4wire")
print(dmm.transducer, dmm.rtdbeta)
This example sets unique beta constants for
3-wire and 4-wire RTDs by creating two
DMM configurations with the settings.
Output:
3.000000000e+00 3.000000000e-
01
4.000000000e+00 5.000000000e-

value
The user type RTD delta value; valid range is 0 to 5
Details
This attribute is only valid when dmm.func is set to "temperature". All other functions generate an
error and return nil when queried.
