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:
- Wide current range (clamp CT input): 20A, 100A, 200A, 500A, 1000A clamps for choice, the highest accuracy of each test point is 0.2%
- Calibrate the error of all electricity energy meters, checking the constant of the energy meter
- 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
- Large color LCD display, All the parameters of each operation function can be displayed within one page
- Easy and reliable operation with two operation modes: touch screen and keyboard. ..
- Measure voltage, current,frequency, power, power factor and phase angle
