dmm.thermocouple
Remarks
This attribute is only valid when dmm.func = "temperature". All other
configurations generate an error and return nil when queried. When the function is
temperature, the thermocouple attribute is only used when the transducer type is
thermocouples (see dmm.transducer (on page 13-173) attribute). For all other
transducer types, the setting will be updated but ignored until the transducer type is set
for thermocouples.
Changing functions with dmm.func (on page 13-137) will reflect the thermocouple
setting for that function.
The factory default and dmm.reset() (on page 13-161) function value is
dmm.THERMOCOUPLE_K.
Example
To set thermocouple type to J:
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMOCOUPLE
dmm.thermocouple = dmm.THERMOCOUPLE_J
dmm.threertd
Attribute
Indicates the type of three-wire RTD being used.
Usage
To read the 3-wire RTD type:
value = dmm.threertd
value: Represents the present type for 3-wire RTD.
To write the 3-wire RTD type:
dmm.threertd = value
value: Represents the desired type for 3-wire RTD.
Use one of the following for value:
dmm.RTD_PT100 or 0 for type PT100
dmm.RTD_D100 or 1 for type D100
dmm.RTD_F100 or 2 for type F100
dmm.RTD_PT385 or 3 for type PT385
dmm.RTD_PT3916 or 4 for type PT3916
dmm.RTD_USER or 5 for user specified type
Remarks
This attribute is only valid when dmm.func = "temperature". All other
configurations generate an error and return nil when queried. When the function is
temperature, the three-wire RTD is only used when the transducer type is three-wire
RTD (see dmm.transducer (on page 13-173) attribute). For all other transducer types,
the setting will be updated but ignored until the transducer type is set for three-wire
RTD.
Changing functions with dmm.func (on page 13-137) will reflect the three-wire RTD
setting for that function.
The dmm.reset() (on page 13-161) function will set this attribute to dmm.RTD_PT100.
