3.13 Battery discharge test function

In the IT8300 series 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
as it can reflect reliability and remaining life of battery.
Press [Shift] + 5(Battery) keys to enter function testing screen of battery
