To calibrate the HI9810382 pH tester, follow these steps:
1. Rinse the electrode tip with purified water and blot it dry. Then rinse it with the buffer solution you will be using for calibration.
2. Press and hold the ON/OFF button until "CAL MODE" is displayed.
3. When "7.01 USE" or "6.86 USE" is displayed with the "CAL" tag blinking, place the tip of the electrode in the correct buffer solution.
4. Once the buffer solution has been recognized, "REC" will be displayed.
5. The stability indicator (#) will blink with "WAIT" displayed until the reading is stable. Wait until the measurement is stored and the stability indicator disappears.
6. To save a one-point calibration and return to measurement mode, press the ON/OFF button. "CAL SAVE" will be displayed briefly.
If you have selected the 2P option, you will need to repeat steps 3-6 with a second buffer solution.
If you have selected the 3P option, you will need to repeat steps 3-6 with a second and third buffer solution.
