1. Introduction
Single phase test bench, is a new generation, high precision energy meter calibration equipment. It adopts advanced technology and best electronic components. It can test mechanical energy meter and electronic energy meter(2 circuit optional), in spite of open or closed test link (I-P link).

2. MAIN FEATURES
*The test bench can be operated by computer or keyboard.
*Adopting with electronic phantom load power source, assuring high stability, security and large output capacity.
*Output current can be adjusted automatically and voltage/current amplifier have fault-self checking function.
*Output current and voltage softly and stop softly.
*Automatically test, alarm and have current/voltage output proof.
*Excellent stability and reliability performance.
*Large output power: Voltage (300VA-1500VA), current (300VA-2500VA)
*Test meters with different meter constant simultaneously.
*Separate voltage output.
*Automatically find black mark for starting and creeping test.
*Having special PC administrative software under Windows, so that to save, check and print data.
