1. The meter can be used as a universal analog input display meter. It can be used 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 input signals 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 between meters, enabling easy implementation of multi-point monitoring.
