1. Using DSP digital signal generating and processing technology makes the measuring output stable and reliable
2. Integrated error 0.05 level (electric energy 0.1 level), high precision good anti-interference
3. Microcomputer management platform, capable of calibrating, transmitting, printing and data management.Specially equip with wireless receiver and emitter to enable remote calibration of AC sampling apparatus.
4. range of voltage current can be preset, and can be shifted automatically
5. large LCD display, tip function, on line help, massive information showing in one screen
6. Can output AC/DC voltage current, equip with standards of power, frequency, phase, power factor, DC voltage current, can display primary value and secondary value at the same time, auto-check the error, save and preview testing results.
7. can test 2~31th order harmonics
8. function of external software calibrating
9. great over-load capacity, can be with 1uFcapacitance (100V)
10. with voltage linkage protection, current limit protection, power amplifier self-closing function
11. going through over-load test, dumping test, misusing test, high temperature aging test make it reliable to use
12. with Germany standard carrying box, light and portableÂ
