Calibration Steps of BH-485-EC Conductivity Sensor

Calibration Steps of BH-485-EC 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 of BH-485-EC Conductivity Electrode

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.
