DZ603-24 Watt Meter Testing Instrument - DZ603-24

Three Phase Energy Meter Test Bench

1- Apply to test all kinds of single and three-phase energy meters, whatever electronic or mechanical type or electromechanical, active meter or reactive meter.

2- Simultaneously test meters with same specifications but different constants

3- operation mode:SMS special keyboard and SMS PC software control

4- display mode: error indicator on each meter position / PC monitor

5- support all test items covered by related regulations, include:
no-load test/ start test/ basis errors test/ voltage influence test
meter constant test/ meter reverse turn test/ energy counting test etc.

6- The electric-driven mechanism controls elevate /lower all of scanning heads

7- simultaneouslyfull-automatic current/voltage measuring range switching

8- output voltage and current adopts soft- stop

9- auto-alarming protection against output voltage short circuit and current open circuit

10- auto capturing the black dot on the rotor before starting test and no-load test

11- Harmonic setting

12- Distortion degree measurement

13- Waveform display

14- support reverse phase-sequence output

15- programmable Voltage/ current/ frequency and phase angle

16- support bar code input, error curve, error limit setting , multi-mode calibration plans setting and equipment authoriy by PC software

17- support data processing and verification certificate printting with customized table format

18- Self- testing, PC software could read out standard meter tested data, and calculate power stability, testing symmetry, display vector chart and waveform, testing harmonic analysis distortion.
