Basic Operating Principle
Signal Acquisition: Acquires the measured DC signal (voltage, current, etc.) through test leads or shunt/voltage divider components;
Signal Processing: Filters, amplifies, or attenuates the signal to meet subsequent processing requirements;
Analog-to-Digital Conversion: Converts the analog signal to a digital signal using an A/D converter;
Data Operation: A microprocessor performs computational processing on the digital signal (such as error correction and unit conversion);
Display Output: The processed result is displayed directly on the screen.

Questions you may be interested in
What is the measurement accuracy of this DC electronic meter?
Our DC electronic meter has a Class B measurement accuracy, meaning the error does not exceed ±1% within the rated measurement range. This meets the high-precision current and voltage monitoring requirements of both industrial and residential applications.
What are the DC voltage and current ranges supported by the electronic meter? Are custom ranges available?
The standard model supports DC voltage 0-1000V and current 0-650A. Customization is available for wider or narrower ranges (such as 0-50V or 0-1000A).
What is the power consumption of the device?
The electronic meter itself has extremely low power consumption, with standby power consumption ≤0.5W, equivalent to the energy consumption of a small LED light. Its impact on the DC system load is negligible, making it particularly suitable for energy-efficient applications such as photovoltaics and energy storage.
What is the device's protection rating?
The enclosure is IP51 rated, suitable for use in dry, dust-free indoor environments (such as distribution boxes and control cabinets).
