• There is a risk of a short-circuit or earth fault. Check for a short-circuit between the external conductor (L) and the
neutral conductor (N) on the test object.
• If there is no short-circuit, you can continue with the test sequence by pressing the button (2).

• Ensure that the test object is switched off. Accidental start-up can lead to injuries and damage.
• Press the button (4) to measure the protective conductor current using the differential current method.
• The protective conductor current measurement (differential current measurement) starts only once the mains volt-
age has been properly established.
• Step 1 (of 2):
• After a measurement time of 5 seconds, the mains polarity is reversed and the
protective conductor current is measured with the reverse mains voltage ("L/N" -
"N/L"). The highest measured value of both measurements is displayed.
• Step 2 (of 2):
• If the protective conductor current is lower than the permissible limit value, a tick
