ETCR4200 Double clamp digital phase meter Clamp meterMIB-INSTRUMENTSETCR4200 Double Clamp Digital Phase MeterⅠ. Introduction ETCR 4200 Double Clamp Digital Phase Meter is another multi-functional meter for site test developed by our company. It performed with the characteristics of high accuracy, high stability, low power consumption and easy use. The phase between AC voltage and AC current can be directly measured. In addition, the circuit power factor and power can be indirectly obtained by manual calculate. Three-phase sequence, transformer wiring group, inductive and capacitive circuit can be identified. Secondary circuit loop and bus protection system can be tested. It can also used to check the phase relationship between CT groups, and whether the meter’s wiring is correct or not, or repair line equipment, etc. ETCR4200 Double Clamp Digital Phase Meter uses large LCD screen, with blue backlight and clear display, showing the appearance of fine luxury.
