1.Important: Isolated monitor lines are only valid when Isolated analog programming modes are 
used for the respective voltage and current control. If local control, digital control or non-iso-
lated APG is used, the non-isolated monitor lines should be used as the isolated monitor lines 
will not accurately reflect the output state of the power supply.
