Dmm.thermistor - Keithley 3700A Series Reference Manual

Series 3700A System Switch/Multimeter Reference Manual
Example
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMOCOUPLE
dmm.units = dmm.UNITS_CELSIUS
dmm.simreftemperature = 30
Sets 30 degrees Celsius as the simulated reference temperature for thermocouples.

dmm.thermistor

This attribute describes the type of thermistor.
Type TSP-Link accessible
Attribute (RW) Yes
Usage
value = dmm.thermistor
dmm.thermistor = value
value
Details
This attribute is only valid when dmm.func is set to "temperature". All other functions generate an
error and return nil when queried. If you use a parameter outside of the ranges listed in the usage
table, a parameter out of range error message is generated.
The thermistor attribute is only used when the transducer type is set for thermistor. For all other
transducer types, the setting is set but not used until thermistor is selected for the transducer type
(see dmm.transducer).
The thermistor setting is saved with the dmm.func function setting, so if you use another function,
then return to "temperature", the thermistor setting you set previously is retained.
Example
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMISTOR
dmm.thermistor = 3000
print(dmm.thermistor)

Recall setup
The thermistor type in ohms, 2252, 5000 or 10000; if you enter any other value, it is
converted as shown in the following table:
Parameter
>= 1950 and < 3500
>= 3500 and < 7500
 7500 and <= 10050

5000
10000
Sets thermistor type to 2252. Note that the
original value is set to 3000, but is
automatically converted to 2252.
