Functional Features

It can measure many power frequency electrical parameters such as voltage, current, active power, reactive power, phase, phase sequence, power factor, frequency, etc. of single-phase and three-phase AC power.
The effective values of the tested single and three-phase AC voltage and current are all true effective values and are not affected by waveform distortion.
Based on the tested electrical parameters, it is possible to determine the wiring group and inductive capacitive load of the transformer, test the secondary circuit and bus differential protection system, read out the phase relationship between the CT of each differential protection group, and check whether the wiring of the energy meter is correct.
10A range, minimum 0.3mA (10A range) can measure angle values, convenient for various light load or transformer no-load operation scenarios.
It can intuitively display three-phase voltage and current vector diagrams, and intelligently distinguish the wiring results of 96 types of three-phase four wire and 48 types of three-phase three wire measuring devices.
The display modes of vector graphics include measurement mode and relay mode, and the phase display range is from 0 ° to 360 °
-180 ° -180 °, convenient for users with different habits.
It can display waveform diagrams of voltage and current, and measure harmonic content and waveform distortion up to 56 times.
Phase measurement can be performed to measure the phase angle relationship between various voltages and currents in real-time.
It can measure the transformation ratio, ratio difference, and angle difference of low-voltage CT.
Built in 32MB Flash memory, the instrument can be seen as a 32MB USB flash drive.
Test results can be saved, including meter information, voltage, current, power and other electrical parameter information, vector diagrams, wiring inspection results, 56th harmonic calculation results, etc. Up to 30000 pieces of data can be saved.
Adopting a 3.2 "TFT true color 320 × 240 LCD screen, the color icons are fully displayed in Chinese, making operation intuitive and convenient.
Built in high-energy lithium-ion battery, long lifespan, convenient to use.
