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, and 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 is percentage. Users can set a custom display range using parameters F0-2 to F0-4. 5. Models equipped with an RS485 interface support communication, enabling easy setup for multiple displays.
