The UPS works in normal mode with a load ratio fluctuation less than 10%.
The UPS generates no battery overtemperature, overvoltage, or overcurrent alarm. No
generator is connected to the UPS.
The mains, batteries, charger, and discharger are normal. No overload alarm is generated.
When the battery test is complete, the test data is used as common test data. Record the data obtained
from the latest five tests.
The shallow discharge test automatically stops in any of the following cases:
 The battery discharge capacity reaches the specified value (10%–50%, 20% by default).
 The discharge voltage reaches the warning threshold (calculated in real time).

The load ratio fluctuation exceeds 10%.
 An alarm is generated.
