• The OV limit feature is always enabled by default whenever you select 
constant current mode. You cannot disable the OV limit feature.
• If the OV value is set to a greater value than the OVP value, the OVP 
value will be adjusted to equal the OV value.
• If the OV value is set to zero, this will result in the output current being 
dropped to zero for limiting.
• The OV value is not applicable for square-wave output.
• The OV value is limited by the range selected. Press Shift > Range to 
select an appropriate range. You can only select a range when the 
output is disabled (the SBY annunciator is illuminated).
