Three Phase Portable Reference Standard Meter field meter calibrator class0.2

 
KE7308B Three Phase Portable Reference Standard Meter
 
Accuracy : 0.05, Test method: Clamp CT input. KE7308B is designed to be compact, 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. With a IP67 protection level, it can be used in many harsh condition.

Functions and features:

1. Wide current range (clamp CT input): 20A, 100A, 200A, 500A, 1000A clamps for choice, the highest accuracy of each test point is 0.2%
2. Calibrate the error of all electricity energy meters, checking the constant of the energy meter
3. 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 in the same loop
4. Large color LCD display, All the parameters of each operation function can be displayed within one page
5. Easy and reliable operation with two operation modes: touch screen and keyboard. ..
6. Measure voltage, current,frequency, power, power factor and phase angle
7. Display waveforms of three phase voltage and current
8. Measure ratio of CT.
9. Current clamp of 20A, 100A, 200A, 500A,1000A to directly measure the comprehensive error
