This equipment refers to the power industry standard and regulation as following: JJG124-93, SD110-83, JJG-307-88, JJG597-89 to design, adopts the technology of modern test, DDS waveform synthesis, CPLD, large-scale integrated power amplifier, etc. With the advantage of strong function, high accuracy, good stability and easy to operate, etc. It can calibrate all kind of AC/DC voltage, current meters, single three-phase active, reactive power meters, energy meters, transmitters and various single three-phase power factor meters, frequency meters and synchronous meters, etc. Widely output range, switching range program, voltage, current output of Buck boost soft switching. Main Features: (1) AC/DC standard output, can used for calibrating various AC/DC indicating meters, transmitters (optional) and energy meters (optional). (2) Digital adjustment output, can output according to percentage, can be directly set output value by press Number Key too. (3) Current, voltage and phase set many common test points, the adjustment of common point in one-time, convenient to use. (4) When calibrate instrument, the gentle uplift-depression of program control electrical quantity to near by specified test point, make a little of program control and fine-adjustment, can conveniently find out test point, now program automatically calculate and display the error of indicating meter. (5) Equipped with interface and software, can carry on automatically calibrating and managing, realize automatically test of multi-range indicating meter via computer. (6) With block structure, convenient to submit and inspect power source.
