voltage and the "Low Battery" indicator turns on. After being used for a couple of hours,
the battery voltage continues to drop to a low level, and the tester will automatically
perform protective shutdown. When the "Low Battery" indicator turns on, the external
power supply is needed to support the tester working while the battery is charging.
