Description
Overview
GAOTek energy meter tester has a versatile meter system that supports simultaneous verification of active and reactive inductive energy meters, as well as electronic energy meters in a four-wire system. It automatically calculates rounding errors, checks load management and transformer monitoring errors, enhancing reactive power accuracy to 0.1%. Features include digital true reactive power measurement, comprehensive pre-power and maintenance checks, event record readings, it can identify and correct various wiring errors, measure waveform and harmonics, and communicate with field terminals and PCs. The meter system also supports barcode scanning, upgrades via U disk or serial port software, and seamless integration with marketing systems.
