Wiring schematic: 485 signal output, the bottom of the sensor has a 4-pole aviation plug, its pin corresponding to the pin definition is as follows: 1. Power positive VCC (Red) 2. Power negative GND (Green) 3. 485A+ (Black) 4. 485B- (Yellow) Note: Make sure the wiring is correct before powering on. Troubleshooting : 1. The meter display value is not correct when for RS485 is output. The meter may not be able to acquire data correctly due to wiring problem or telecommunication serial port failure. Please check whether the wiring is correct and firm, whether the serial port is occupied, and whether the serial port is set correctly; 2. If it is not the above reasons, please contact service.
