dmm.thermistor
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 thermistor attribute is only used when the transducer type is set for
thermistor. For all other transducer types, the setting will be updated but not used until
thermistor is selected for the transducer type. See the attribute dmm.transducer (on
page 13-173).
Changing functions with dmm.func (on page 13-137) reflects the thermistor setting for
that function.
The factory default and dmm.reset() (on page 13-161) function value is 5000 ohms.
Example
To set thermistor type to 3000:
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMISTOR
dmm.thermistor = 3000 -- this gets adjusted to 2200
print(dmm.thermistor) --> "2200"
dmm.thermocouple
Attribute
Indicates the thermocouple type.
Usage
To read the thermocouple type:
value = dmm.thermocouple
value: Represents the present thermocouple type
To write the thermocouple type:
dmm.thermocouple = value
value: Represents the desired thermocouple type. For value, use one of the following:
dmm.THERMOCOUPLE_J or 0
dmm.THERMOCOUPLE_K or 1
dmm.THERMOCOUPLE_T or 2
dmm.THERMOCOUPLE_E or 3
dmm.THERMOCOUPLE_R or 4
dmm.THERMOCOUPLE_S or 5
dmm.THERMOCOUPLE_B or 6
dmm.THERMOCOUPLE_N or 7
