Product introduction

SMG2000 series Digital Display Clamp-on Phase Meter is special designed for voltage, current and phase tests, it is in high-precision, low price, portable hand-held, dual-channel input measuring. It's easy to measure the phase between U-U, I-I and U-I, identify the inductive circuit ,capacitive circuit and the phase sequence of three-phase voltage, detect the wiring group of transformer, test the secondary circuit and bus differential protection system, display the phase relationship among the CT groups of a differential protection system, and check if the wire of electric meter was correctly connected. When testing customers do not need cut off the tested current which input by slip core current transformer. When measuring the phase between U1 and U2, the two input circuit loop are completely isolated, so the possible misconnection is absolutely avoided, which may result in short circuit and may even burn the meter. The monitor of the device is high-contrast LCD screen, and the character in which could be as high as 25mm, and can be freely rotated approximately 70 °, which helps to obtain the best visual effects.

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

Phase meter, clamp phase meter, digital clamp phase meter

The Characteristics of the products
1. Withstand Voltage
Parts between voltage input terminal and meter shell, parts between the iron core of the clamp-current transformer and secondary windings can stand 1000V/50Hz. Parts between the two voltage input terminals can stand Sinusoidal AC Voltage 500V/50Hz for 1min when testing.
2. Insulation Resistance
Between meter circuit and meter shell, between the two voltage input terminals:≥10MΩ
