PH meter Calibration : 1. Disolve each buffer solution in 250 mI of distilled water 2. Immerse the electrode into the pH 6.86 solution. (under the temperature of 25) .3. 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.4. Immerse the electrode in pH 4.00 solution.-Press "CAL buttonfor 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 JIf incorrect, please repeat the calibrationIf approximate pH of your test solution is known to be above 7.0, calibrate the meter using 6.86 and9.18 solution.To do this , please follow the calbration chart，The third step is the calibration method for 9.18 point
