Single Phase Portable Meter Test System MHTS1.1

Functions

1) Standard meter integrated with voltage source and current source

2) 7"touch screen LCD.  ARM in-built system

3) Output with high stability and low distortion

4) Four working mode :

-Portable single phase meter test equipment (optional: three position mount rack)

-Portable single phase reference standard meter

-Portable single phase meter tester with current source

-Standard meter which can give output impulse for calibration of the unit.

5) With enough protection : Current open, current over load, voltage short and etc

6) Can do below test : Start test, creep test, basic error test, standard deviation tester, dial test, etc..

7) Can do voltage dip test and power interrupt test and power ramp up and down test

8) 2-21 times harmonic ; Can set amplitude and phase; and do harmonic analyze and get waveform

9) With self-test function namely can perform monitoring of output voltage, output current, output phase, power factor, output frequency, output harmonic waveform and power output stability and etc..
