dmm.threshold
Remarks
This attribute is only valid when dmm.func is equal to:
―frequency‖
―period‖
―continuity‖
All other configurations generate an error and return nil when queried.
For ―frequency‖ and ―period‖ this refers to a threshold voltage range (0 to 1010, default
10). For ―continuity‖ it refers to a threshold resistance in ohms (1 to 1000, default 10).
Errors will get generated if parameter value does not make sense for selected function.
Changing functions with dmm.func has no effect on this setting.
The factory default and dmm.reset function value is 10.
Example
To set the threshold range for frequency to 30:
dmm.func = "frequency"
dmm.threshold = 30
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.
Changing functions with dmm.func has no effect on this setting.
The factory default and dmm.reset function value is dmm.THERMOCOUPLE.
Example
To set transducer to thermistor type:
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMISTOR
