2. Disolve 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 3 seconds and release

Rinse and dry the electrode with distilled water as before.
6. Test calibration by inserting electrode into pH 9.18 buffer solution,
gently swirl electrode until digital display stabilizes. Display should read between 9.16 and 9.20.
(if necessary repeat calibration procedure)
Attention
The instrument need recalibrate in the following condition.
1.Long time no use or use very long time after calibration
2.The electrode is used very frequently
3.The testing accuracy requirement is very high
4.Press the "CAL"button long time in the air carelessly
Maintenance:
Always replace protective cap after using digital meter to keep electrode from drying out due to prolonged exposure to air,
which leads to slow and/or unstable readings.
If electrode has been dried out immerse it into distilled water for a few hours.
LowBatt
When the display value is fuzzy or unshown , The battery should be replaced promptly.Pay attention to the polarity of battery.
