DZ603-6  Three Phases Energy Meter Test equipment

Main Performance:

1. Shall carry out completely automatic calibration items such as running with no load, starting, basic error, standard distortion and 24 hours variation etc according to testing regulations: four quadrant: positive, negative, active or reactive error test, automatic shift the input of all kinds of pulse.

2. The tested meters maybe same specification but different communication protocols.

3. Shall carry out tests such as demand cycle and its display, time interval error, register combined error and daily error.

4. Communication test, GPS broadcast time calibration, meter data verification, regarding record meter number.

5. According to regulations, carry out various influence value test, voltage falling and interruptions shall be carried out.

6. Automatically adjust black spot, calculate time for starting test and running with mo load test according to regulations.

7. Shall adopt fixed time and fixed quality burden methods to carry out the reading test, and different time interval with different burden tests are available.

8. Shall display the voltage and current wave diagram with same phase: shall set and measure 2~21 times harmonic wave and measure the distortion degrees.

9. Data be processed and printed automatically, and the table lay out shall be set freely according to user's requirements, transfer data by all M2S port.

10. Support: bar code input, error curve, error limit setting, multi-mode calibration plans and equipment management authority etc.
