Product features
1UHV-926 Three phase Energy Meter Calibration InstrumentAdopting a multi processor combination with a high-speed floating-point DSP processor as the core, the 6-channel synchronous 16 bit ADC converter ensures synchronous calculation of voltage and current.
2. Adopting an 8.4-inch 800 × 600 resolution industrial grade TFT LCD screen, the display is clear, beautiful, and informative. It can complete functions such as setting calibrated meter parameters, electrical parameter measurement, error testing, vector graphics, etc. in one screen.
3. The human-machine interaction method combines buttons and touch screen, making it easy to operate.
4. It has the function of distinguishing 144 types of incorrect wiring (48 types for three-phase three wire and 96 types for three-phase four wire), and accurately and clearly describes the error information in text.
5. It can test the 2-51st harmonic content and total harmonic content of three-phase voltage and current in the power grid, and display them intuitively with a bar chart.
6. It can display the waveforms of voltage and current channels.
7. The built-in current transformer starts at a minimum of 2mA and can be used to detect misconnections of the energy meter under no-load conditions during high power supply and high timing.
8. Built in large capacity Flash storage space, USB communication interface, plug and play for uploading test data.
9. The test has no blind spots and can measure all types of electric energy meters at home and abroad.
10. Multiple working power supply modes can be used, including mains power supply and on-site testing line power supply.
