6. Place the meter back to the buffer solution to test calibration.If incorrect,please repeat the calibration
7. 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:
1. If the tester was used or lay aside long time: recalibrate it.
