6) During the calibration process, press key to exit from the calibration mode. The meter can perform one-point, two-point and three-point calibration. Calibration guide icons appear on LCD. 5.5 Measuring pH Screw off the KCL storage bottle, and put it aside (do not dump or spill the KCL solution). Prepare a cup of distilled water, and rinse the electrode in it for a few seconds. - Page 12 5.5.1 According to the pH isothermal measurement principle, the closer the test sample’s temperature is to the calibration solution’s, the higher the accuracy of the measurement. This principle is recommended to follow when conducting tests for the best result. Example: If users were to test samples at 150˚F, we recommend warming up the calibration solutions to the same temperature before performing calibrations in order to get the most accurate readings.

Loosen the cap, take out the electrode and rinse in distilled or water before taking a measurement. Insert the electrode and tighten the cap after measurements to prevent the solution from leaking. If the storage solution is cloudy or moldy, replace the 3M KCL solution. Oakton electrode storage solution 00653-04. -
