6.4.4 Procedure-Manual Calibration

1.Obtain two buffer solutions. Ideally, the buffer pH values should bracket the range of pH values to be measured.

2.Remove the sensor from the flow cell. If the process and buffer temperatures are appreciably different, place the sensor in a container of tap water at the buffer temperature. Do not start the calibration until the sensor has reached the buffer temperature.
