2.1 Introduction to main functions
l Check the energy error of all mechanical and electronic energy meters, and can check the main and auxiliary meter in the same circuit or the active and reactive meter in the same circuit at the same time; check all energy meter constants;
l Measure TA transformation ratio;
l Measure field electrical parameters and indicators of each phase (U, I, P, Q, Φ, F);
l Measure the indicating errors of various energy meters;
l Measure current and voltage harmonics, and support the measurement of 51 harmonics;
l Measure current and voltage waveforms;
l U disk upgrading system, download the calibration data to achieve paperless office;
l Use T9 Chinese input method commonly used in mobile phones, extremely easy to input Chinese characters;
l Detect automatically the changes in the clip-on ammeter errors;
l Support the measurement of small current (support <5mA current testing, and facilitate the initial installation and test of measuring devices;l Read multifunctional energy meter data;
l More complete wrong wiring recognition functions, and IB access and reverse connection of TV, TA polarity can be recognized;
l The instrument power is supplied with battery and test circuit, and can be online charged.Technical Data
