Explanation
The safety extra-low voltage is measured to check for compliance
with the specifications regarding the rated voltage of devices with
SELV/ PELV
voltages.
The test socket is supplied with mains voltage.
Exception: Test samples with protection class III
Application
Class II, Ua, safety extra-low voltage
(e. g. plug-in power supply unit

Circuit diagram
VDE 0701-0702
Insert the shock-proof plug of the portable test sample into the
test socket of the appliance tester. (Class I; Class II)
The test sample is supplied with mains voltage. (Class I; Class II)
Use the test probes to scan both poles of the output side.
The current voltage is shown on the display of the appliance
tester.
Measurement
Connect the mains plug of the test sample to the test socket of
the appliance tester.
Connect the test probe and the measuring line to the appliance
tester according to the connection diagram.
Tap the “
Start
” button.
Move the test probe and the contact surface of the measuring line
to the poles of the secondary side.
The appliance tester measures the voltage between the two poles.
Check the measured voltage value for compliance with the
technical data of the test sample.
Tap the “
Stop
” button to stop the test.
The “
Test result
” screen opens.
