The “CHANGED” message is displayed for a sec ond to show that the new OCP
trip level is now in effect. If the OCP settings are not chang ed, “NO CHANGE”
will be displayed. The power supply will exit the OCP menu and the display

OCP annunciator turns on.
Checking 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 blink. The “OCP TRIPPED” message also appears on the
display.
Clearing the Overcurrent Condition
W hen the OCP condition occurs (the “OCP TRIPPED” message is shown on
the display), the
OCP annunciator flashes. When it was caused by external
voltage sources such as a battery, disconnect it fi rst. Clear the overcurrent
condition by adjusti ng output current level or b y adjustin g OCP trip level.
The following steps show how to cle ar the overcurrent condition and get back
to normal mode operation. In the following steps, the display will go back to
“OCP TRIPPED” if you let the display time out after about several seconds.
