2 Enable the output.
The OFF annunciator turns off and the display will go to
the meter mode.
3 Enter the OCP menu and set the desired trip level.
LEVEL 7.5 A
You will see the above message on the display when you
enter the OCP menu. Adjust the knob for the desired OCP
trip level.
4 Enable the OCP circuit.
OCP ON
You will see the above message after pressing
.
5 Exit the OCP menu.
CHANGED
The CHANGED message is displayed for a second to show
that the new OCP trip level is now in effect. If the OCP
settings are not changed, NO CHANGE will be displayed.
The power supply will exit the OCP menu and the display
will return to the meter mode. Check that the OCP
annunciator turns on.
Checking the OCP operation
To check OCP operation, raise the output current to near
the trip point. Then very gradually increase the output by
turning the knob until the OCP circuit trips. This will cause
the power supply’s output current to drop to zero and the
OCP annunciator to flash. The OCP TRIPPED message also
appears on the display.
