Example
dmm.func = "twowireohms"
dmm.filter.window = 0.25
dmm.filter.enable = dmm.ON
Set the filter window for 2-wire ohms to 0.25
and enable filtered measurements.

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.
