 Overview

HM2000B Double Clamp Digital Phase Meter is specially designed for measuring voltage, current and phase. It is characterized by high precision, low price, portable hand-held and dual-channel input measuring. It’s easy to measure the phase between U-U, I-I and U-I, identify the inductive/capacitive circuit and the phase sequence of three-phase voltage, check the wiring group of transformer, test the secondary circuit and busbar differential protection system, display the phase relationship among the CT groups of a differential protection system, and check if the wire of electric meter is correctly connected. Under test, you do not need cut off the tested current which is inputted by clamp-current transformer. When measuring the phase between U1 and U2, the two input circuit loops are completely isolated, so it can completely avoid short circuit and burning down the meter caused by misconnection. The display of this device is high-contrast LCD screen, and the character in which could be as high as 25mm, and can be freely rotated approximately 70 ° to obtain the best visual effects.

The shell of the device is made of engineering insulating material, together with a rubber anti-vibration protection casing for safety and reliability.
