Product details
product overview
The wireless inspection device has wiring simulation function and can measure three-phase three wire and three-phase four wire current imbalance. Quickly identify hidden faults, power theft, leakage and other abnormal situations. This instrument is a powerful assistant for conducting power inspection work.
Functional Features
Adopting industrial grade TFT large color screen, each function of the instrument is displayed on one screen, making it easy for users to see at a glance when using.
Simultaneously measure multiple electrical parameters such as energy error, voltage, current, power, phase, frequency, etc., and display vector diagrams and line checking results.
Optional 5A, 100A, 500A, 1000A clamp gauges can be used to directly measure the transformation ratio of low-voltage current transformers.
Real time measurement of 2-21st harmonic and waveform of A, B, and C three-phase voltage and current, to timely understand the power supply quality of the power grid.
Equipped with a USB interface, it can connect to a USB flash drive, creating a super large space for easy data copying.
