How To Use:
Connect the test probe of this instrument to the wire to be tested (cannot be pinched directly by hand), which can be a wire end, socket or the middle part of the phase wire (when measuring in the middle part of the phase wire, the insulation layer of the wire needs to be stripped Go, the wire core inside can be measured. At this time, pay special attention to safety to prevent electric shock. For the convenience of users, there is a special test Clamp/Holder in the instrument accessories. Insert the test Clamp/Holder on the metal probe of the test and tighten it. Conveniently Clamp/Holder it anywhere for measurement). At this time, the meter will indicate the state of the open phase and the sequence based on the phase of the light emitting diode (LED) and the buzzer
1. LED for open phase check: three orange LEDs, indicating U phase, V phase and W phase respectively.
2. LED for phase sequence check: one red LED and one green LED respectively
3. Draw strap: put it on the wrist to prevent the instrument from slipping off the hand.
4. Test lead.
5. Test red corresponds to U (R) phase (L1, R);
Yellow corresponds to V () phase (L2, S);
Green corresponds to W (B) phase (L3, T)
