Details
The transducer type must be set to temperature and the transducer must be set to 3-wire RTD before
you can set the RTD type.
Example
dmm.measure.func = dmm.FUNC_TEMPERATURE
dmm.measure.transducer = dmm.TRANS_THREERTD
dmm.measure.threertd = dmm.RTD_D100
Set the measure function to temperature.
Set the transducer type to 3-wire RTD.
Set the RTD type to D100.
