- Page 11 4.4.2 Screw off the electrode storage vial and use pure water to rinse off electrode; Blot dry the electrode with Kimwipe/filter paper/clean tissue to remove excess wa- Pic-11 ter (NEVER rub the glass membrane). Then dip electrode into pH 7.00 buffer at least 1 inch deep (see Pic-11), stir it for a few seconds and let it stand.
- Page 12 5. pH Measurement 5.1 How to Take pH Measurement 5.1.1 Power on the meter to enter measurement mode. 5.1.2 Rinse the electrode with pure water for a few seconds. Blot dry the electrode with Kimwipe/filter paper/clean tissue. 5.1.3 Submerge the electrode into your sample solution at least 1 inch deep (see Pic-12).
- Page 13 5.5 Manual Temperature Compensation The default pH electrode has a built-in temperature sensor so the temperature compensa- tion will be automatic (ATC on screen). When you use a pH electrode without a tempera- ture sensor, you would want to use the manual temperature compensation function to lower the pH measurement error.
- Page 14 6.1 How to do the parameter setting In measurement mode, long press to enter parameter setting P1. Then press to change menu from P1 to P2…P5. For details, please see the following table. P1 — Select pH buffer series (USA— NIS) 1.
- Page 15 7. Electrode Cleaning The meter is only as accurate as the electrode is clean. Always thoroughly rinse off the electrode before and after each measurement with distilled water or deionized water in a container or with a wash bottle. To remove excessive water, just shake them off or blot dry with Kimwipe/filter paper/ clean tissue.
