Operating steps: 
1.  Press [Trig] key to start OPP test. If within range, PASS the test and the 
board will display as follows: 
 
9.996V      0.0007A 
0.01W  49.10W  PASS  STOP 
 
If not, there is FAULT and the board will display as follows: 
 
9.996V      0.0007A 
0.01W  48.6W  FAULT  STOP 
 
2.  End test. The User should return back to setting screen for resetting. 
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 
 
3.12 Battery discharge test function 
In the IT8800  series electronic load, constant current mode is applied for 
capacity test with programmatic setting of cutoff level/capacity/discharging time 
If cutoff level 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 the 
test, the voltage, time and discharged capacity of the battery can be observed. 
Battery discharge test is a necessary step before battery replacement for it can 
reflect reliability and remaining life of battery.
