5.6.1.2 Performing a Shallow Discharge Test
Before performing a shallow discharge test, ensure that:
The UPS works in normal mode with a load rate 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.

Starting a shallow discharge test
When the battery test is completed normally, 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 rate fluctuation exceeds 10%.
