ZC-610A digital dual clamp phase volt ampere meter is designed for the field measurement of voltage, current and phase and the design of a high precision, low price, portable handheld, dual channel input measurement equipment. The table can be easily between the field measurement U-U, I-I and U-I phase discrimination of inductance and capacitance circuit and three-phase voltage phase sequence, detecting the transformer connection group, test secondary circuit and the mother difference protection system, read the phase relationship between the differential protection CT in these two groups, check meter wiring correct and not used.
