After use, switch off pH meter, use the water clean the electrode and replace the protective cap.
DO NOT USE DISTILLED OR DEMONIZED WATER FOR STORAGE PURPOSES.
Large fluctuations in readings could be due to lack of calibration, dry electrode or rundown batteries.

Allow the reading to stabilize and using a small screwdriver adjust the calibration trimmer to read 6.9.
