Detailed Description

Brief Introduction ST-9020 D Series: ST9020-6 Single-phase Energy Meter Testing Equipment adopt two structures: integrative structure and cabinet & rack structure. 6 single-phase mechanical, elcetromechnical, electronic or multi-tariff watt-hour meters can be tested at a time. The equipment can be controlled both via computer and via special keyboard. With high working efficiency, single-phase watt-hour meters can be tested automatically according to regulations and program defined by the user. Features and Functions Basic error measurement, starting and creeping testing Controlled via PC or keyboard Color mark of mechanical meter automatic capturing, saving time for creeping starting Current automatic short circuit at positions without meters, no external short circuit wiring Perfect software for computer controlling and management, bar code input available, convenient for interface to MIS system, and also the function of on-line assistance; Current and testing points can be randomly set via software, suitable for the requirements of different regulations. Special error display for each meter position, convenient for meter adjustment Quick connection terminal, convenient for meters loading and unloading Photoelectric scanning heads collective overturn, convenient for meters loading and unloading Testing bench is made of high-class aluminium material, arts and crafts good, beautiful and decent Special keyboard operation, easy and convenient Voltage short circuit and current open circuit alarming and protection Standard pulse output (FH: 10KHz, FL: 1Hz), convenient for recalibration of the equipment Options Optional communication function for communication interface checking and testing of time interval error and energy value indication error of tested meters, and also the testing of register assembled error and demand indication Optional GPS clock calibrator for time telling and fundamental frequency daily timing error testing of single-phase multi-tariff watt-hour meters Specifications Accuracy: class 0.2, 0.1 Voltage output Range: 220V （0.01% ~120% adjustable） Resolution of amplitude: Better than 0.01% of the whole range Current output Range: 0.01A～120A（0.01% ~120% adjustable） Resolution of amplitude: Better than 0.01% of the whole range Max.
