AC and DC Voltmeter/Ammeter with Digital Display
Digital display meters include voltmeters, ammeters, frequency meters, 4~20mA passive meters, temperature controllers, and teaching instruments for measuring the electrical signals.
Program overview
This product series is designed for 4-20mA passive meter applications. It integrates 24-bit high-precision ADC, low-noise PGIA, display driver, and other functional modules, which are suitable for high-precision meter applications. The internal integrated temperature sensor can realize temperature compensation. It integrates advanced linear calibration algorithm. Calibration operation is simple and coefficients can be stored for saving external memory.
