3.7 Battery test function
The CC,CP and CR mode can be applied for battery-capacity test with discharge
conditions. Discharging time and discharged capacity (AH or WH) of the battery can be
always observed during the test. When the battery discharge meets the setting
termination conditions, the E-load will completes the test and stop loading.
