dmm.offsetcompensation
Attribute
Indicates the offset compensation setting for the DMM.
Usage
To read the offset compensation:
value = dmm.offsetcompensation
value: Represents the present offset compensation setting.
To write the offset compensation:
dmm.offsetcompensation = value
value: Represents the desired offset compensation setting. Set to one of the following:
dmm.ON or 1 to enable offset compensation
dmm.OFF or 0 to disable offset compensation
Remarks
This is the offset compensation setting for the DMM, and it applies to the selected
function as indicated by dmm.func (on page 13-137). Querying the setting when the
selected function does not support it will cause nil to be returned.
The command applies when dmm.func is:
"fourwireohms"
"commonsideohms"
"temperature"
When dmm.func = "temperature", the command applies only when the transducer type
is 3 or 4-wire RTD (for all others, it is ignored). Set this command like you would for 4-
wire ohm measurements.
All other function settings will generate an error if the command is received. Also, an
error will be generated if the value is invalid.
Changing functions with dmm.func (on page 13-137) will reflect the offset
compensation setting for that function.
The factory default and dmm.reset() (on page 13-161) function value is dmm.OFF.
Example
To enable offset compensation for 4-wire ohms:
dmm.func = "fourwireohms"
dmm.offsetcompensation = dmm.ON
dmm.open()
Function
Opens the specified channel or channel pattern.
Usage
dmm.open(<ch_list>)
ch_list: string listing the channel or channel pattern to open.
