Field Portable Reference Standard Meter Three Phase Class 0.1 2 Input Channel

Portable Three Phase Field Meter Tester for energy meter with 100A clamp CT class 0.1

KE7303 Portable Three Phase On-site Electric Meter Tester
 
Accuracy : 0.1, Test method: clamp CT and terminal input. It's light and small, which is convenient for on-site test. And it can be used to test the error of three phase energy meters and field electrical parameters of power grid.
 
Features:

1. Calibrate the error of all electricity energy meters, checking the constant of the energy meter
2. Simultaneous checking of the primary meter and the secondary meter in the same loop, or simultaneously checking of the active power meter and reactive power meter inthe same loop
3. Measure voltage, current, frequency, power, power factor and phase angle
4. Simultaneous measure and display waveforms of three phase voltage and current
5. Detectthe error change of the clamp automatically; ensure the accuracy stability ofthe clamp and the instrument in the long run.
6. Measureratio of CT, VA burden of the metering loop from VT and CT secondary terminals.
7. Allocate clamp of 20A, 100A, 500A, 1000A to directly measure the comprehensive error
8. Measurethe 2^nd – 51^st harmonics of current and voltage
9. Display vector diagram, judge the wiring right or wrong automatically
10. Read the information of energy meter with barcode scanner (optional)
11. Battery, test lead power or external power for choices
12. Communicate with PC, download calibration data through USB flash disk, RS-232 or bluetooth
13. Firmware can be upgraded through removed disk by users themselves
14. Save and browse the testing data, data storage quantity is up to 1000 pieces.
