value
The type of four-wire RTD:
▪ dmm.RTD_PT100 or 0 for type PT100
▪ dmm.RTD_D100 or 1 for type D100
▪ dmm.RTD_F100 or 2 for type F100
▪ dmm.RTD_PT385 or 3 for type PT385
▪ dmm.RTD_PT3916 or 4 for type PT3916
▪ dmm.RTD_USER or 5 for user-specified type
Details
This attribute is only valid when dmm.func is set to "temperature" and dmm.transducer is set
to dmm.TEMP_FOURRTD. For all other transducer types, the attribute is set but is not used until the
transducer type is set for four-wire RTD.
All other functions generate an error and return nil when queried. An illegal parameter value error
message is generated if the value specified is not a supported RTD type value as listed in the usage
table.
The four-wire RTD setting is saved with the dmm.func function setting, so if you use another
function, then return to "temperature", the four-wire RTD settings you set previously are retained.
Example
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_FOURRTD
dmm.fourrtd = dmm.RTD_PT3916
Sets the type of four-wire RTD for PT3916.
