Automatic 0.1 Accuracy Electric Energy Meter Calibrator For 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
