Disolve each buffer solution in 250ML of distilled water

Immerse the electrode into the PH 6.86 solution,(under the temperature of 25)

Press the "CAL"(calibration)button for 5 seconds and release

Display will start flashing 6.86

Wait until the display stops flashing.

Rinse the electrode with distilled water and dry it with filter paper.

Immerse the electrode in PH 4.00 solution,

Press"CAL"button for 5 seconds, then press and release immediately second time

Reading will start flashing 4.00

Wait until display stops flashing

Rinse and dry the electrode with distilled water as before.

Place the meter back to the buffer solution to test calibration. If incorrect, please repeat the calibration

If approximate PH of your test solution is known to be above 7.0,calibrate the meter using 6.86 and 9.18 solution. To do this, please follow the calibration chart, The third step is the calibration method for 9.18 point.

Kindly Reminder:

If the tester was used or lay aside long time: recalibrate it.

If you open battery case or replace battery: recalibrate it.

The glass bulb of the electrode is fragile. Don't touch it by hard tools and fingers, suck the water on it gently when cleaning.
