It STEP 4: Clean the electrode in distill water and dry it, immerse the electrode in Ph 4.00 standard buffer solution
It STEP 5: Press the “CAL” button. Wait until the display digital is 4.00pH. Then complete pH 4.00 calibration
It STEP 6: Clean electrode and dry it, put the meter into PH 9.18 standard buffer solution. Check if reading is correct between 9.17-9.19pH.

Note:
Clean the electrode with distilled water every time before and after use.
