1. The meter can be used as a universal analog input display meter. It can be paired with various sensors that have analog output to display the actual physical quantity, such as temperature transmitters, frequency converters, motor speed, pressure, liquid level, concentration, and more. 2. The instrument supports 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 display shows values as a percentage by default. Custom display ranges can be set using parameters F0-2 to F0-4. 5. Models with RS485 interface support communication, enabling easy integration for multiple display setups.
