1. The meter can be used as a universal analog input display device. It is compatible with sensors that have analog output to display real-time physical measurements such as temperature, frequency, motor speed, pressure, liquid level, and concentration. 2. The instrument supports either current input or voltage input. 3. Default input ranges: 0–10V, 2–10V, 0–20mA, 4–20mA. By adjusting the bias and gain parameters, it can be configured for other inputs within the 0–10V or 0–20mA range. 4. The default display mode shows values as a percentage. Custom display ranges can be set using parameters F0-2 to F0-4. 5. Models equipped with an RS485 interface support communication, enabling easy integration for multiple displays.
