High Precision Portable Meter Tester Three Phase With 120A Clamp CT Class0.05 480V 

KE7308 Portable Three Phase Meter Tester
 
Accuracy : 0.05, Test method: clamp CT and 20A terminal input. It adopts compact engineering  case design, which is convenient for on-site test. In addition, it is able to calibrate 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.
 
 

Descriptions:

1. Wide current range (direct connection): 0.05 A to 20A, the highest accuracy of each test point is 0.05%
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. 7” color LCD display, All the parameters of each operation function can be displayed within one page
5. Two operation modes: touch screen and keyboard. Easy and reliable operation..
6. Measure voltage, current,frequency, power, power factor and phase angle
7. Simultaneous measure and display waveforms of three phase voltage and current
8. Measure ratio of CT.
9. Allocate clamp of 20A, 100A, 200A, 500A,1000A to directly measure the comprehensive error
