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 conveniently measures the phase between U-U, I-I, and U-I in the field, identifies inductive and capacitive circuits, determines the phase sequence of three-phase voltages, checks transformer wiring groups, tests secondary circuits and busbar protection systems, reads the phase relationships between various CTs in differential protection, and verifies the correctness of electricity meter wiring.

        It uses clamp-type current transformers to input the measured current, allowing measurements without disconnecting the circuit under test. When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, thereby 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 in height, and the screen angle can be freely adjusted by approximately 70° for optimal visual clarity.

       The instrument housing is made of engineering insulating material and comes with a rubber anti-vibration protective cover, ensuring safety and reliability.
