dmm.transducer
Attribute
Indicates the transducer type.
Usage
To read the transducer type:
value = dmm.transducer
value: Represents the present transducer type.
To write the transducer type:
dmm.transducer = value
value: Represents the desired transducer type.
For value, use one of the following:
dmm.TEMP_THERMOCOUPLE or 1
dmm.TEMP_THERMISTOR or 2
dmm.TEMP_THREERTD or 3
dmm.TEMP_FOURRTD or 4
Remarks
This attribute is only valid when dmm.func = "temperature". All other configurations
generate an error and return nil when queried.
NOTE This attribute setting affects what other temperature-supported attributes
get used. There are various attributes that are only applicable when the
transducer type is a certain type. Although the transducer type needs to
match for the attribute setting to be used, the transducer type does not
need to match to change the setting. For example, the transducer type
does not need to be set to dmm.TEMP_FOURRTD to change the
dmm.fourrtd (on page 13-137) attribute setting.
Changing functions with dmm.func (on page 13-137) will reflect the transducer setting
for that function.
The factory default and dmm.reset() (on page 13-161) function value is
dmm.THERMOCOUPLE.
Example
To set transducer to thermistor type:
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMISTOR
dmm.units
Attribute
Indicates the units for voltage and temperature measurements.
