Multifunction Volt-Ampere Phase Meter

Overview

This instrument is a high-precision, low-cost, handheld, dual-channel input measuring device specifically designed for on-site voltage, current, and phase measurements. It allows for convenient on-site measurementsU-U、I-INo content provided for translation.U-IDuring phase identification, distinguish between inductive and capacitive circuits and the phase sequence of three-phase voltage, detect transformer winding connections, test secondary circuits and differential protection systems, and read differential protection groups.CTPhase relationships between components, checking the correct wiring of electrical meters, etc. The measured current is inputted using a clamp-on current transformer, thereby eliminating the need to disconnect the measured circuit during measurement. MeasurementU1-U2During the phase between, the two input circuits are completely insulated and isolated, thereby completely avoiding potential misconnections that could cause short-circuits in the measured lines, leading to the destruction of the measuring instrument. The display features a high-contrast LCD screen with legible characters.25mmScreen angles are freely adjustable.70° for optimal visual effects.

The instrument housing is made of engineering insulating material and is equipped with a rubber vibration-proof protective sleeve, ensuring safety and reliability.
