dmm.refjunction = state
state
The reference junction type:
▪ dmm.REF_JUNCTION_SIMULATED or 0
▪ dmm.REF_JUNCTION_INTERNAL or 1
▪ dmm.REF_JUNCTION_EXTERNAL or 2
Details
This attribute is only valid when dmm.func is set to "temperature". All other functions generate an
error and return nil when queried.
This attribute only applies when the transducer type is set to thermocouple. For all other transducer
types, the reference junction may be set, but it is not used until the transducer type is set to
thermocouple.
The reference junction setting is saved with the dmm.func function setting, so if you use another
function, then return to "temperature", the reference junction settings you set previously are
retained.
Example
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THERMOCOUPLE
dmm.refjunction = dmm.REF_JUNCTION_SIMULATED
Enables the simulated thermocouple
reference junction.
