Operation After Protection Operation
During the test, low-voltage over-current, low-voltage over-voltage, high-voltage
over-current, high-voltage over-voltage, discharge and other phenomena will
lead to protection action. All the protection information will be displayed on the
LCD screen. At this time, the following steps should be followed:
1. Turn off the power (disconnect the obvious disconnect point).
2. Conduct the test again after finding out the test condition and dealing with it
accordingly.
Confirm that it is not the cause of the test product, turn off the low voltage
capacitor for 10 seconds, turn on the power switch, try to test again and check
the test equipment.
