SM852B Three-Phase Rotation Tester, Portable and Wide-Range Three-Phase Digital Rotation Meter for Electrical Testing with Clip, AC 60-600V

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, a socket, or the middle section of the phase wire (when measuring in the middle section of the phase wire, the wire insulation layer must be stripped; the wire core inside can be measured. At this stage, take particular care to avoid electric shock. For user convenience, there is a special test clip in the instrument accessories. Insert the test clip onto the metal probe of the test lead and tighten it. Easily attach it anywhere for measurement). At this time, the counter indicates the open phase status and the sequence based on the phase of the light-emitting diode (LED) and the buzzer. 1. Open phase control LED 1. Three orange LEDs, indicating phase U, phase V, and phase W respectively. 2. LEDs for phase sequence control: one red LED and one green LED respectively. 3. Pull slant: place it on your wrist to prevent the instrument from slipping out of your hand. 4. Test lead. 5. Test lead: red corresponds to phase U(R)(L1,R); yellow corresponds to phase V(Y)(L2,S); green corresponds to phase W(B)(L3,T).
