• Immerse into solution up to the max immersion level.
• Stir gently and wait until the display stabilizes.
• After use, switch off pH meter, use the water clean the electrode and replace the protective cap.
• Large fluctuations in readings could be due to lack of calibration, dry electrode or rundown batteries.
CALIBRATION
• Immerse the tester 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
Calibration is now complete.
