Calibration of BH-485-EC Digital Conductivity Sensor
Calibration of BH-485-EC Digital Conductivity Sensor, Calibration condition: 1.this conductivity sensor is directly with Standard RS485 Modbus. 2.this sensor is for K=10.0 conductivity sensor. 3.the standard buffer is 12.88ms/cm 4. calibration software is Modbus poll on computer. Calibration steps. 1.Put conductivity sensor in standard buffer:12.88ms/cm. 2.Send value 2 in Register 14(it's to choose right standard buffer). 3.Then send value 2 in Register 13 to start calibration. After several minutes, you can compare the the measured value in Register 1 with standard buffer, it will be ok when it's in 1% accuracy. or check the constant value in Register 15. Calibration finished.
