Calibration:

1. Turn on the pH meter.

2. Dissolve each buffer solution in 250 ml of distilled water.

3. Immerse the electrode into the pH 6.86 solution (under the temperature of 25℃).

4. Press the “CAL”(calibration) button for 5 seconds and release；

– Display screen will start flashing “6.86”；

– Wait for it until the display screen stops flashing；

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

5. Repeat the above steps with 4.01 pH buffer powder and 9.18 pH buffer powder.

Note:

Calibration is required in the following conditions.

– Lengthy periods of inactivity

– Very frequent use

– The testing accuracy requirement is very high

– The “cal” key was pushed and the electrode was exposed to air for an extended period of time
