dmm.simreftemperature
Attribute
Indicates the simulated reference temperature for thermocouples.
Usage
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).
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 simulated reference temperature 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 simulated
reference temperature setting for that function.
The factory default and dmm.reset() (on page 13-161) function value is 23°C.
Example
To set 30 degrees Celsius as the simulated reference temperature for thermocouples:
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMOCOUPLE
dmm.units = dmm.UNITS_CELSIUS
dmm.simreftemperature = 30
dmm.thermistor
Attribute
Indicates the type of thermistor to use.
Usage
To read the thermistor type:
value = dmm.thermistor
value: Represents the present thermistor type in ohms. The value will be one of the
following: 2200, 5000 or 10000.
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
Converted value
<3500
2200
Between 3500 and 7500
5000
