Jiangxi JULYWELL Science & Technology Development Co., Ltd

Product Overview This device is designed in accordance with the verification procedure JJG124-2005 "current meter, voltmeter, power meter and resistance meter verification procedure", JJG307-2006 and related national standards designed three-phase 0.05 level table source integrated device. The core technology of the table in the device is a high-precision frequency AC collector consisting of a digital signal processor (DSP) and a 16-bit high-speed analog-digital converter, and the signal part of the source is also a controlled sine and terabotal signal source using DSP and 16-bit high-speed digital analog converter. The device has the characteristics of high precision, stable and reliable operation, convenient and flexible operation. The display features a 6.5-inch TFT color LCD screen with clear chart characters. Key features and features 1. Various frequency meters (voltage meters, current meters, power meters, frequency meters, power factor meters, phases) can be tested automatically or manually table), the basic error of single-phase AC energy meter and three-phase AC energy meter (option). 2. The accuracy is 0.05 when measuring AC voltage, current, and active power, and the accuracy of energy measurement is guaranteed to be 0.05 due to the installation of digital/frequency converters (DFcs) and multiple current ranges above 60KHz operating frequencies. 3. Distortion waves with 2 to 31 harmonics can be generated, and the number, number, magnitude and phase of harmonic-to-base wave can be programd. 4. It has an RS-232 or USB interface. Through the computer software, the PC control unit can be automatically or manually inspected, and the results can be processed and managed. 5. It is equipped with a large-capacity non-volatile memory, which can store 300 pieces of detected data for inspection and upload.
