Detailed Product Description

Automatic 0.1 Accuracy Electric Energy Meter Calibration Of Single Phase Energy Meter

 

 

This is a no-Ioad on-site test bench for single phase energy meters integrated with reference meter and source.

 

Main features

1.  Accuracy class:0.1

2.  Simultaneous measurement for 1-3 static single phase energy meters

3.  Measurement for single phase local prepayment smart energy meters and single phase remote prepayment smart energy meters

4.  Automatic/manual measurement of creeping and starting (of energy meters )

5.  Wide measuring range reference meter integrated

6.  Proofreading of constant by measuring pulse number,time,and start-stop power value;dial measurement according to number of KWh,time and number of pulse;preset number of KWh,the dial will stop accordingly

7.  Automatic measurement of register

8.  GPS reference clock integrated,time pairing for energy meters

9.  Individual voltage loop for each testing position
