Details
This command specifies the relative offset value that can be applied to new measurements. When
relative offset is enabled, all subsequent measured readings are offset by the value that is set for this
command.
You can set this value, or have the instrument acquire a value. If the instrument acquires the value,
read this setting to return the value that was measured internally.
Example
CURR:REL .5
CURR:REL:STAT ON
Set the relative offset for current measurements to 0.5.
Enable relative offset.
