dmm.thermistor
Attribute
Usage
9-118
Indicates the simulated reference temperature for thermocouples.
To read the simulated reference temperature:
value = dmm.simreftemperature
value: Represents the present simulated reference temperature
To write the simulated reference temperature:
dmm. simreftemperature = value
value: Represents the desired simulated reference temperature in Celsius (0°C to
65°C), in Fahrenheit (32°F to 149°F) or in Kelvin (273°K to 338°K).
This attribute is only valid when dmm.func = "temperature". All other
configurations generate an error and return nil when queried.
Changing functions with
The factory default and dmm.reset
To set 30 degrees Celsius as the simulated reference temperature for thermocouples:
dmm.func = "temperature"
dmm.units = dmm.UNITS_CELSIUS
dmm.simreftemperature = 30
Indicates the type of thermistor to use.
To read the thermistor type:
value = dmm.thermistor
value: Represents the present thermistor type in ohms. The value can be one of the
following: 2200, 5000 or 10000. less than 3500 is 2200
To write the thermistor type:
dmm.thermistor = value
value: Represents the desired thermistor type in ohms (1950 to 10050). The value
parameter is converted to 2200, 5000 or 10000 as follows:
Parameter
<3500
Between 3500 and 7500
 7500
