• Stir gently and wait until the display stabilizes.
• After use, switch off the pH meter, use the water clean the electrode and replace the protective cap.
DO NOT USE DISTILLED OR DEIONIZED WATER FOR STORAGE PURPOSES.
• Large fluctuations in readings could be due to lack of calibration, dry electrode, or rundown batteries.
CALIBRATION
• Immerse the handheld pH meter up to the maximum immersion level in pH 6.86 buffer solution
• Allow the reading to stabilize and using a small screwdriver adjust the calibration trimmer to read 6.86
