Multifunctional Energy Meter Tester

Our organization manufacturing, exporting and supplying ZDN2903 Multifunctional Energy Meter Tester which is designed and combined with parameters testing, energy meter calibration, wiring judgement, harmonic analysis in one. It adopts high precision and linearity voltage and current transformer, also have clamp current transformer for test without cut off circuit.
It adopts big screen color LCD, kinds interface. vector diagram displaying and wiring judgement, histogram for harmonic wave. Internal big memory power-off memory storage for 1000 sets test data. Backstage software management and analysis for test data. It has engineering plastic shell, nice shape and easy operation.
Unfold the back holder to support on the desk operation and handheld operation, also have wrist strap to fix on hand operation.
