2) Modular design allows customized configurations on hardware and software, customer-friendly

3) Perform all basic tests like warm up, creep test, start test, basic errors, standard deviation and etc.

4) Perform dial test with pulse counting & timing base with KWH value

5) Mode of tests: Fully-automatic, or manual operation by manual control touch screen (MCU)

6) Able to test all types of single phase and three phase mechanical meters, electronics meters, CT/PT

operated meter, smart meter, closed-link meter, and etc..

7) Error calculation display with reset buttons on each meter position

8) Flexible Quick connector device (QCD) for convenient changeover from three phase meter

to single phase meter

9) Black mark search & capture for rotation disk

10) Able to calibrate mechanical or electronics meters with different constant at the same time

11) Test Records save in database with MDB format or other required format

12) Calibrate parameters including voltage, current of each phase, phase/phase difference,

active/reactive/apparent power of each phase, total active/reactive/apparent power, total power factor,

frequency, etc. with real time display of vector graph

13) Harmonic test 2-21times and analysis/display of harmonic

14) With facilities to test apparent maximum demand recorded in meters and carry out the register test

(the client should provide meter communication protocol for this function)

15) Self-testing function for all phases power, total power stability, symmetry of 3 phase voltage and current

16) PC software (communication by RS232) can realize MIS net interface connection function, can easily

upgrade in the future if necessary
