1、 Functions and characteristics of DC ammeter:

1. The display rate, communication address, baud rate, etc. of the DC ammeter can be set through buttons on the panel, making it very flexible and convenient to use.

2. The DC ammeter can choose analog output, with outputs ranging from 4 to 20mA, 0 to 12 to 20mA, etc.

3. The DC ammeter can choose two alarm outputs to monitor the upper and lower limits of the measured parameters.

4. The DC ammeter can choose RS-485 digital interface and use standard MODBUS-RTU protocol.

5. The DC ammeter can have two optional switch inputs, which can monitor the switch status within the system.

6. The DC ammeter has digital zero and digital calibration, high accuracy, and extremely high cost-effectiveness.
