  3. Long press button for more than 1 second to enter pH calibration mode. The icon “CAL” will appear on the LCD and then pH value 7.0 (4.01, or 10.01) will be displayed on the LCD.
  4. When reading becomes stable and if the display value is not 7.0 (4.01 or 10.01), press or to adjust the reading till it matches 7.0 (4.01 or 10.01). The adjustable ranges are 3.50 to 4.50, 6.50 to 7.50 9.50 to 10.50
