Details
The command applies when
dmm.func
is set to
"fourwireohms"
,
"commonsideohms"
or
"temperature"
.
When
dmm.func = "temperature"
, this attribute applies only when the transducer type is 3- or 4-
wire RTD. Set this command as you would for 4-wire ohm measurements.
This command is automatically set to
dmm.ON
when
dmm.drycircuit
is set to
dmm.ON
and
dmm.func = "fourwireohms"
or
"commonsideohms"
.
The offset compensation setting is saved with the
dmm.func
function setting, so if you use another
function, then return to
"fourwireohms"
,
"commonsideohms"
or
"temperature"
, the offset
compensation setting you set previously is retained.
If you query this attribute and the function is not
"fourwireohms"
,
"commonsideohms"
, or
"temperature"
, nil is returned.
Example 1
dmm.func = "fourwireohms"
dmm.offsetcompensation = dmm.ON
Enable offset compensation for 4-wire ohms.
Example 2
dmm.func = "temperature"
dmm.transducer = dmm.TEMP_THREERTD
dmm.offsetcompensation = dmm.OFF
Disable offset compensation for 3-wire RTD
temperature measurements.
