Product Introduction
This instrument is a high-precision, low-cost, handheld, dual-channel input measuring device specifically designed for on-site measurement of voltage, current, and phase. It can conveniently measure the phase between U-U, I-I, and U-I in the field, identify inductive and capacitive circuits, determine the phase sequence of three-phase voltages, inspect transformer wiring groups, test secondary circuits and busbar protection systems, read the phase relationship between CTs in differential protection groups, and check the correctness of watt-hour meter wiring. It uses a clamp-type current transformer to input the measured current, allowing measurements without disconnecting the circuit. When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, thereby fully avoiding potential short circuits caused by miswiring and preventing damage to the instrument. The display features a high-contrast LCD screen with characters up to 25mm high, and the screen angle can be freely adjusted by approximately 70° for optimal visual effect.
The instrument housing is made of engineering insulating material and comes with a rubber anti-vibration protective cover, ensuring safety and reliability.
Product Features
☆、Withstand Voltage: Between the voltage input terminals and the instrument case, and between the clamp-type current transformer (current clamp) core and the clamp handle and secondary winding coil, it can withstand 1000V/50Hz; between the two voltage input terminals, it can withstand 500V/50Hz sine wave AC voltage for 1 minute.
☆、Insulation Resistance: Between the digital dual-clamp phase volt-ampere meter circuit and the case, and between the two voltage input terminals: ≥10MΩ
