OPERATION

appear around the cap. This is normal with pH electrodes and

they dissolve when rinsed with water.

• Turn the meter on sliding the switch on the top.

• Immerse into solution up to the max immersion level. • Stir gently and wait until the display stabilizes. Readings are automatically compensated for temperature variations.

• After use, switch off 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 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 6.9.

Calibration is now complete.

ALWAYS USE FRESH BUFFERS FOR CALIBRATION.
