Three-Phase Voltage, Current and Power Multi-Functional Electrical Parameter Measuring Instrument with Print Interface

Product Description

Product Description

CN8902 three-phase digital electric parameter measuring instrument is a kind of intelligent instrument which uses microcontroller technology to analyse and process the signal.Its working principle is: the measured voltage and current signals are first transformed into smaller voltage signals, which are sent to a high-speed analogue-to-digital converter to be converted into digital quantities that can be processed by the microcontroller. The microcontroller processes the collected digital quantities and displays the final calculated results in digital form, or transmits the data to other devices in the form of serial communication.

The digital electrical parameter measuring instrument has the following advantages:
1. The measured signal value is true RMS.
2. Direct digital display, no reading error.
3. It is also suitable for waveform distortion signals. 
4. one instrument can measure several parameters.

Digital electric parameter measuring instrument is widely used in motor, substation, power plant and other tests.
