Description:
This calibrator adopts analog signal conditioning circuit based on the principle of potential difference measurement, the digital circuit with 16-bit DSP and the 32-bit ARM 9 as the core technology.
In calibration process, it can automatically set test points and accuracy standards in compliance with relevant regulations. This calibrator should be used in combination with voltage (or current) standard transformer, voltage (or current) load box, voltage (or current) booster, and voltage (or current) source.
Applications:
- Nation-level utility companies
- Governmental bureaus of metrology
- Big energy meter manufacturers
Primary Competitive Advantages:
- High quality product
- DSP & ARM9 as the core technology
- Easy to carry
