The load will switch after receipt of every trigger signal. The load will switch
between A and B value for one time. Time of operations is shown at bottom
right.

3.11 OCP test function

The IT8300 series electronic load is provided with overcurrent protection test
function (OCP). Under OCP test mode, when input voltage reached Von value,
delay for a while for the electronic load to latch. Ascend value by step value at
regular interval. At the same time, check the load input voltage and judge
whether it is higher than standard voltage value. If higher, it indicates that OCP
does not occur. Repeat current stepping operation till the load operates to the
cutoff current. At the same time, check whether the cutoff current value is within
target scope. If yes, PASS the test, otherwise FAULT. If lower, it indicates that
OCP has occurred. Check whether the existing current value is within target
scope again. If yes, PASS the test, otherwise FAULT.
Operating steps:
1. Press [Shift] + [CC] (OCP) keys to enter OCP test function setting screen.
