Single phase site energy meter test instrument type KP-P1001-A (without voltage and current source) is an ideal instrument to test all kind single phase energy meters accuracy below 1.0, especially for meters on site. During tests, the tested meter must be on load condition (that means the tested meter must be working). The instrument tests the errors by comparing energy impulse from the tested meter with energy impulse from the reference meter inside the instrument.
The instrument is box structure, very light and easy to carry, it is a very ideal device for power supply authority to test the installed meters on site.
