¡ñ High brightness, high definition, high resolution liquid crystal display (640*480 touch
¡¡ screen).
¡ñ The system utilizes high-speed, high-accuracy digital multiplier to test all parameters
¡¡ such as active and reactive power, voltage, current, frequency, phase etc and calibrates
¡¡ them through software.
¡ñ This device has no potentiometer, which protects it from error change caused by transpor-
¡¡ tation or other factors, and increases stability and reliability of the system greatly.
¡ñ The system adopts the digital absolutely reactive testing technology that is first inven-
¡¡ ted in our country. This technology makes reactive testing realize a situation that it is
¡¡ not influenced by voltage and current unbalance, phase angle dissymmetry and frequency c-
¡¡ hange.This technology also increases the reactive accuracy rate up to 0.1% the first time
¡¡ in our country.
¡ñ Assure the power accuracy (0.1% or 0.05%) between the temperature of -20¡æ to +40¡æ.
¡ñ Test electric energy in four quadrants.
¡ñ Equipped with ¡À0.2 %5A transformer (including split non-repeat errors, touching errors,
¡¡ outside magnetic field interference errors, angle errors and so on).
¡ñ Equipped with 20A, 100A, 500A, 1000A transformer to directly test low voltage gauging in-
¡¡ tegrative errors and CT changes cooperated with 5A transformer.
¡ñ The automatic switching range of voltage is from 30V to 480V. Current input value is 5A;
¡ñ Wide range of working electric resource is AC85~260V, 380V over voltage protect.
¡ñ Identify three-phase three lines 48 kinds errors and three-phase four lines 96 kinds err-
¡¡ ors in four quadrants, showing hexagonal nomogram with any line connection.
¡ñ The hexagonal nomogram of any kind of line connection can be used for line check training,
¡¡ after showing incorrect identification.
¡ñ Able to test the 2nd ~51st harmonic wave of three-phase voltage and current, and save all
¡¡ harmonic wave¡¯s data.
¡ñ Able to show three waveforms of voltage and current simultaneously.
¡ñ Provide error calibrating function, so that it is convenient to calibrate errors, but it
¡¡ needs password.
¡ñ Save all testing data of 60000 meters, including working parameters, conveniently for an-
¡¡ alysis.
¡ñ Able to communicate with PC, very convenient to connect to the original database and man-
¡¡ agement system.
¡ñ Able to update software via flash disk or USB.
¡ñ Able to be equipped with <PEC watt-hour meter management system> software to realize a si-
¡¡ tuation that working without paper.
¡ñ Check single-phase, three-phase three lines, three-phase four lines active and reactive in-
¡¡ duction type watt-hours meter and electronic watt-hours meters(able to receive impulse of
¡¡ electronic watt-hours meter) automatically or by hand.
¡ñ Able to calibrate voltage, current, power, power factor, phase and frequency of electrote-
¡¡ chnical instrument and transmitter by comparison.
¡ñ Intelligently read the data of multi-functional electric meter.
¡ñ Test secondary pressure drop and secondary loaded.
¡ñ Simultaneously calibrate the errors of three-phase Watt-Hour meter including active and re-
¡¡ active, and also check the errors of main meter and sub-meter at the same time.
¡ñ Support MMC card, flash disk, etc.
¡ñ Unique ¡°no dirt inside¡± structure design; heat elimination & ventilation district and in-
¡¡ ner box are separated, so that the inside is able to be kept clear permanent and make sure
¡¡ stable operation of device.
¡ñ Equipped with plastic box to hold this device, light and convenient.
