Specifications

1.Certificate: ISO 9001;
2.Accuracy class:0.05;
nvenient to test I-P close link meters
with Isolated current transformer

DZ603-16 Three-Phase Close-Link  meters test equipment

Main features:
1. Equipped with current isolating CT, current of each meter position is isolated
by 1: 1, which makes it possible to test the three-phase closed loop meters without
disconnecting the voltage and current links
2. The tested meters may be same specification with different constants. The meters
such as single phase mechanical, electromechanical and electronic meters can be tested simultaneously
3. Equipped with the high precision reference meter with wide range
4. Randomly set the basic current and the maximum current, no limit to the current range
5. Automatic warning when the voltage output is in short circuit (overload) and the
current output is in open circuit (overload)
6. Automatic capturing rotor mark or carry out start testing and running with no
load test, and automatic judges the testing results
7. Randomly set 2 to 21 harmonics, error curve can be made, value can be calculated
8. Fully automatic meter testing controlled by computer, intelligent data processing
and network data sharing
9. Support Meter bar code reading
10. Randomly setting of reporting table and certificate formats
11. It can be equipped with GPS clock calibrator to check the daily error, time-interval
error, time projection error, the maximum demand; check constant, register
display error and RS485 communication
12. The unit of measuring ambient temperature and relative humidity is optional
13. The unit of measuring the consumption of meter under test is optional
