1. Start-up measurement, intelligent identification, non-contact measurement
2. Three-in-one multimeter + electric tester + phase sequence detector
3. Phase sequence induction detection: put the nibs close to the phase line ABC test points respectively, the green indicator light turns on, and the screen displays R, indicating that it is forward direction; the result, the red indicator light turns on, and the screen displays L, indicating that it is reverse direction
4. Line breakpoint detection: In the NCV non-contact voltage detection mode, check the breakpoint position along the line when the single-strand line is charged
5. Fine stainless steel watch needle: the negative input terminal is closely connected with the test lead, which is firm and durable, and is suitable for circuit maintenance and testing of various electrical appliances and small electronic components
6. In NCV mode, when a nearby AC voltage is detected, the
