Digital Phase Sequence Meter AC Current Meter Three-Phase Phase Sequence Meter SM852B Shipped without plug or battery, 856423mm

Used to perform the phase and state sequence of the open phase. Counter detected via buzzer sound and LED display to verify if the phase sequence of the current three-phase circuit is correct. Measurement frequency range: 20Hz~400Hz Measurable voltage range: 60 V ~ 600 V (three-phase AC) Operating voltage: 60 ~ 600 V (three-phase AC) Maximum withstand voltage: 2000 V/min (pulse voltage 4000 V) Continuous use: 200V AC, no more than 60 minutes; 600V AC, no more than 4 minutes. 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).Note: All data is measured manually; please allow for a 1-3cm error. Due to differences in lighting and display, there may be some color variation; the actual product received shall prevail.
