Variable Offset
The remote variable offset can be used when the dc couple function
is remotely selected. The offset voltage must be referenced to the
External offset common (pin 4) of the remote input connector. It
must be electrically isolated from the controlling system. The
following table shows the offset range and remote offset
requirements for probe and adapter combinations.
