6-When measuring is completed, impedance of
L-N and PSC value appears on the screen
7-Press TEST button if re-test is necessary
When symbol from , ,
appears lower left corner, and if the voltage
exceeds 260V, the measurement will not take place
5.2.5-Using The RCD Function
You can select UL Voltage by Pressing and hold
F3 button for more than two seconds (25V or 50V).
Uf value appears is the contact voltage on the
screen.
