1. The meter can be called a universal analog input display meter. It can be matched with various sensors with analog output to display the actual physical quantity. Such as temperature transmitter, frequency converter, motor speed, preure, liquid level, concentration, etc. 2. The instrument supports current input or voltage input. 3. Default adaptation: 0-10V, 2-10V, 0-20mA, 4-20mA. By setting the bias parameter and gain parameter, it can adapt to other inputs in the range of 0-10V, or 0-20mA. 4. It is displayed as a percentage by default. You can also set your own display range through F0-2 ~ F0-4. 5. The instrument with 485 interface has already supported the communication between the meters, and it is convenient to realize multiple displays.

Parameter description The parameters are described as follows: 1.F0 Attendant array display Parameter parameter name Scope and description Defaults Read write F0-0 Collected value monitoring Monitor the percentage of the current analog input value. Range: 0-100.0% read-only F0-1 Display value monitoring In the display value in "Monitoring Menu" is calculated by F0-0, F0-2~F04. read-only F0-2 Display accuracy The number of decimal places displayed in the "Monitor Menu", range: 0-3. 1 Read write F0-3 Show minimum In the "monitoring menu", the value corresponding to "acquisition value" is 0%, the range: -1999~9999 0 Read write F0-4 Show maximum In the "Monitoring Menu", the value corresponding to the "Acquisition Value" is 100.0%, the range: 1999~9999 1000 Read write F0-5 Offline status 0: Not disconnected; 1: Disconnected. (Disconnection detection is set by F1-4) (starting from V2.10) read-only 2.F1 parameter group-analog configuration parameters Parameter parameter name Scope and description Defaults Read write F1-0 Input type selection 0: 0~10V or 0~20mA corresponds to 0~100.0%; 1: 2~10V or 4~20mA corresponds to 0~100.0%, and 0 when it is lower than 2V or 4mA. 0 Read write F1-1 Input filter time Analog input filter time, range: 0~10.000s. The longer the filtering time, the stronger the filtering 0.200 Read write F1-2 Input gain Range: 0~1000.0%. 100.0 Read write F1-3 Input offset -99.9~99.9%, with 10V or 20mA as 100.0%. 0.0 Read write F1-4 Drop detection threshold Range: 0.0-100.0%. This value is based on 0-10V or 0-20mA as 0.0-100.0% as a reference (and F1-0 and gain offset are not related), the detection is not started if it is le than 0.5, and there is a hysteresis of 0.3. When the input signal is lower than this value, the meter displays E.oFL. (Starting from V2.10) 0.0 Read write F1-5 Enter the parameter setting select
