Operation Test
Warning
Mains voltage applied to appliance
The Power test supplies the equipment under test (appliance),
connected to the 230V test socket, with the rated voltage of that
socket.
The Tester measures the power used by the appliance and displays
the reading in kVA. There is no test duration limit on the Power tests.
Once supplied with power, the appliance will be supplied until the
operation is cancelled. This will allow appliances with slow start-up
speeds the time to ramp up to their working state.
