1. The meter can be called a universal analog input display meter. It can be matched with sensors with analog output to display the actual . Such as temperature transmitter, frequency converter, motor speed, pressure, 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 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 , and it is convenient to realize multiple displays.
