If necessary for pH calibration point 1, modify the buffer value using the up/down arrows. Insert the sensor
into the point 1 buffer, wait until the sensor reading is stable and confirm with ENTER.
Repeat the operation with the point 2 buffer. Before putting the sensor in the point 2 buffer, clean the
sensor with distilled water and dry it well (with tissue paper) to avoid contamination of the buffer. If at any
time during the calibration process you are not sure of the calibration, you can exit without confirming by
pressing ESCAPE.
