Press the “measure” or calibrate button to begin reading the pH once your electrode is placed in the buffer. Allow the pH reading to stabilize before letting it sit for approximately 1-2 minutes. Once you have a stable reading, set the pH meter to the value of the buffer's pH by pressing the measure button a second time. Setting the pH meter once the reading has stabilized will allow for more accurate and tuned readings. Although not necessary, if you stir your buffer before measuring be sure to stir all other buffers and samples in the same way. Rinse and pat dry with a lint-free tissue, like Kimwipes or Shurwipes, in between buffers. Press the measure button to begin reading the pH once your electrode is placed in the buffer. Once your reading has stabilized, set the pH meter to the value of the buffer's pH by pressing the measure button. You can use distilled water to rinse. Use a lint-free tissue, like Kimwipes or Shurwipes, in between buffers to dry the electrode.
