KE7308A Three Phase Portable Reference Standard Meter
KE7308A is a combination of a three-phase standard meter of class 0.05%, which is used to calibrate or test three phase, single phase, active or reactive energy meter on site, include Residential meter, Industrial and Commercial meter. And also it can be used as voltage, current and power meter to measure AC parameter of three phase power grid.
The unit can be used with various types of clamp-on CTs and current sensors. Therefore it is possible to easily and accurately test both CT and direct-connected meters.

Product functions:

  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 the 2nd - 51st harmonics of current and voltage
  9. Display vector diagram, judge the wiring right or wrong automatically
  10. Industrial grade engineering plastic suit case, which has a safety protection level of up to IP67.
  11. Read the information of energy meter with barcode scanner (optional)
  12. Battery, test lead power or external power 3 power supply ways for choices
  13. Communicate with PC, download calibration data through USB flash disk, RS-232 port
  14. Firmware can be upgraded through USB port by users themselves
  15. Save and query of testing data
