key to start OPP test.
when input voltage reaches 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. and the board will
display as follows:
If not, there is FAULT and the board will display as follows:
9.996V 0.0007A
0.01W 48.6W FAULT STOP
End test. Press

again to exit.
NOTE
If the set OPP voltage value is higher than the power voltage value, the OPP will fail to
operate and the board will display as follows:
9.996V 0.0007A
0.01W 0.1W FAULT STOP

Battery discharge test function
In the IT8912E electronic load, constant current mode is applied for discharge
test with programmatic setting of stop voltage/capacity/discharging time If stop
voltage is set as the stop condition, the system determines whether the battery
is about to reach the set threshold value or unsafe status when the battery
voltage is low, and if yes, an automatic stop will be activated. During test, the
operator can observe voltage, discharging time and discharged capacity of
battery. Battery discharge test is a necessary step before battery replacement
for it can reflect reliability and remaining life of battery.
