+ | |||
+ | - Press and release the mode key until your digital display indicates pH mode. This key toggles between the pH, mV and Rel mV modes. | ||
+ | - Press the setup key twice and then press the enter key to clear an existing standardization. | ||
+ | - Rinse the electrode with distilled water using a squeeze bottle and immerse the rinsed electrode into pH 4 (pink) buffer solution. | ||
+ | - Press std again to access the Standardization mode. The selected buffer group is displayed briefly. Wait for the reading to stabilize. | ||
+ | - Press std again to initiate standardization. The meter will automatically recognize the buffer (4.00 not 7.00) and then return to the Measure screen. | ||
+ | - Repeat steps 3-6 with the pH 10 (blue) buffer solution. When the meter accepts the second , pH 10, buffer solution, it will briefly display the percent slope associated with the electrode’s performance prior to returning to the Measure mode. If the electrode is within the range of 90 – 102%, the GOOD ELECTRODE message will appear. | ||
