4.16 OPP Test Function

IT8700P+ series electronic load is provided with overpower protection test
function (OPP Test). Under OPP 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
OPP does not occur. Repeat power stepping operation till the load operates to
the cutoff power; if lower, it indicates that OPP does occur. Check whether the
existing power value is within target scope again. If yes, PASS the test.
