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

key or any composite function key to exit
dynamic test function. Repeat Steps 1-10 to continue parameter setting
and operation of dynamic test.
3.12 OCP test function
The IT8912E 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; if lower, it indicates that OCP does occur. Check whether the
existing current value is within target scope again. If yes, PASS the test.
