Details
The command applies when dmm.func is set to "fourwireohms", "commonsideohms", or
"temperature".
When dmm.func is set to temperature, the open detector setting is only used when the transducer
type is thermocouple. For all other transducer types, it is set, but not used until the transducer type is
set to thermocouple.
The open detector setting is saved with the dmm.func function setting, so if you use another function,
then return to "fourwireohms", "commonsideohms", or "temperature", the open detector
setting you set previously is retained.
An error is generated if dmm.func is set to any function other than "fourwireohms",
"commonsideohms", or "temperature". If you query the setting for any other function, nil is
returned.
Example
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMOCOUPLE
dmm.opendetector = dmm.ON
