Clearing the overcurrent condition
When the OCP condition occurs (the OCP TRIPPED message is
shown on the display), the OCP annunciator flashes. When it
was caused by external voltage source such as a battery,
disconnect it first. The following steps show how to clear the
overcurrent conditions 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.
1 Readjust the OCP trip level or the output current level.
Lower the output current level below the OCP trip point
after pressing
or raise the OCP trip level
by using the knob after pressing .
2 Move to the clear mode.
OCP ON
You will see the above message after pressing
. If you changed the output voltage level,
press the twice. Turn the knob to the right
until the OCP CLEAR message appears on the display.
3 Clear the overcoltage condition and exit this menu.
Now, when you press again, the DONE
message is displayed for a second and the OCP
annunciator will not flash any more. The output will
return to meter mode.
