|Functions and Features:||● The devices are fully made by aluminum alloy materials and the table board is composed of fireproofing and heat-proof materials.
● The output voltage and current use soft startup and stop. It has the protection functions of voltage short circuit, current open circuit and power amplification exception.
● The device has the features of high stability, good reliability and large output power.
● High level of autoimmunization. The coexistence of special small keyboard and PCs, convenience to use.
● The electric meters of same type and different constants can be checked at the same time (each constant at up and down rows).
● It can be appended 2-21 harmonic at the base-band wave of the working frequency, the amplitude and phase can be set up at you wish. You also can make a harmonic analysis of the output value and draw a waveform graph.
● It has the test and measurement items like time graduation-moving, ration graduation-moving, constants rectification and graduation-moving errors.
● PC software for Windows98 (Windows2000, Windows XP) is written by Delphi5. Control devices and data queries are efficient. It also has the perfect functions of reports print, data statistics and assets maintenance.
1. The accuracy class of the devices: 0.05 grade; 0.1 grade
