Test terminal is / are for connecting the correct lead of the tested
installation: L to L(Live); N to N(Neutral); E to E(Earthing).
5.2 Test Lead Checking
After connected the test leads with the testers, please plug the power cable on (220V/50Hz current socket), so you can 3-LED lamp whether it is correct. If P-E & P-N are displayed green signal light, but the red color LED do not light up. It is in good normal condition. If not, it may be incorrectly connect with P and N. You need to put off those test leads and check it then plug into the correct one.
Connecting inadequately terminal P & terminal N during the measurement it may cause to have a leakage.
5.3 Press I△n button switch, it causes RCD breakers for the nominal residual currents (I△n) as the previous trip current in constant Below LCD display the default connecting current value.
Default Value: I△n 30mA 0°/180° 0°
