The meter is a universal analog input display device that can be used with various sensors featuring analog output to display real-time physical measurements, such as temperature transmitters, frequency converters, motor speed, pressure, liquid level, concentration, and more. It supports both current and voltage input signals. Default input ranges include 0–10V, 2–10V, 0–20mA, and 4–20mA. By adjusting the bias and gain parameters, the meter can be calibrated for other inputs within the 0–10V or 0–20mA range. The display defaults to percentage reading, but custom display ranges can be set using parameters F0-2 to F0-4. Models equipped with an RS485 interface support communication between multiple meters, enabling easy multi-point monitoring.
