☆ Instrument Appearance | |
NO. | Function |
1 | The excitation coil can generate a programmable and adjustable power frequency AC magnetic field of 0 to 1200 A/m, and can rotate 360°. |
2 | The electric meter tray is equipped with all electric energy meter test terminals, which can complete the error test of the energy meter and can be rotated 360°. |
3 | The manual control area can manually control the rotation of the excitation coil and the meter tray, making it easy to manually adjust the direction of the magnetic field and apply it to the energy meter under test. |
4 | The console can control the size of the magnetic field and the output of the three-phase energy meter testing device, making it convenient for users to perform manual testing. |
5 | Standard power source for excitation power supply and three-phase energy meter calibration device. |
