AL318 Watt-hour meter tester

Implementation of standards.

GB/T 11150-2001、JJG 597-1989、JJG124－2005

Main function and characteristics

Watt-hour meter tester, go together with precise electric current with each other a feeling machine, can under the situation that not dismantle form and continuously give or get an electric shock, examination electric power the error margin of the form, and keep watch on charged barbed wire net electric voltage, electric current, power factor, and have a great achievement power. The tiny controller control: As long as constant and school of the importation electricity check number, can test to find out an electricity error margin. Establish light an electricity head to account bad with move to account to differ two kinds of diagraph ways. Be applicable to various different diagraph situations. The school checks instrument need not battery, is directly used exchanges electric voltage power supply by diagraph. Establish low frequency pulse exportation, convenience from check with send check. The physical volume is small, the weight be light, the convenience take and the spot the examination use.
