DK-45B1 multifunctional standard meter (Three-phase electric energy meter calibration equipment tester) is according to power industry standard JJG596-1999 and JJJG597-89 calibration regulation, adopts the technology of DSP high speed and high precision data acquisition, CPLD, embedded computer system, TFT true-color display, etc. Designed for measuring single three-phase energy meter calibration equipment, also be used as common standard meter. With the function of wide-range AC/DC voltage and current measurement, can be used as common indicating device standard. It is with the advantage of small volume, light weight, strong function, high accuracy, good stability, flexible and convenient to use, and easy to carry, also equipped with RS232 interface and software, so it can take the place of many standard meters such as voltage meter, current meter, power meter, energy meter, distortion analyzer, phase-frequency meter, magnetometer, phase-sequence meter, etc. Avoid trivial testing and calculating works in the process of calibration equipment. So it is the ideal equipment to power department used for testing equipment. Main Features: 1. Can measure many electrical quantities of voltage, current, power, electric energy, phase, frequency, power factor, etc. 2. Can measure DC voltage, high current. 3. Can directly read all equipments degree of stability, distortion, symmetry, standard deviation, phase balance, phase sequence, etc. 4. Can measure and display phase between three-phase voltage, three-phase current and voltage-current at the same time. 5. Can automatically measure influence each other between three-voltage equipment and current regulation system. 6. Can automatically measure the change rate of phase-shift voltage (current). 7. Can measure of starting current to three-phase equipment. 8. Can carry on semi-auto calibrating to instrument of all monitoring. 9. Can simultaneously acquire input pulse of three energy meters, calibrate instrument be made up of three single-phase standard meters. 10. Can real-time display vector diagram of voltage, current. 11. Can measure 2~31 times harmonics, display bar charts of harmonics. 12. Equipped with microcomputer interface and software, can carry on calibrating and managing with computer, output standard Chinese character forms.
