Checking the OCP operation
To check OCP operation, raise the regulated output current
slowly. Watch the voltage drawn by the load as it reaches
near the trip point. Then very gradually increase the output
current using the arrow keys until the OCP circuit trips.

After adjusting the OCP value, you can also press
[Protect]
again to
save the changes made or press
[Shift]

[Exit]
to discard the changes
made.
•
The OCP feature is always enabled by default whenever you select
constant current mode. You can disable the OCP feature by disabling
the output protection state from the Utility menu.
•
If the OCP value is set to a lesser value than the OC value, the OC value
will be adjusted to equal the OCP value.
•
The OCP value is not applicable for square-wave output.
•
The OCP 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).
