11. Compensate for altitude in metric units when operating in DO measurement mode. The default value is 0 meters (sea level). The level is adjustable from 0 to 8,900 meters. Once the salt compensation level has been set and stored, the lower portion of the display will show the term “High-”. - Page 9 10. The pH electrode has now been calibrated once. To maximize measurement accuracy, General recommends rinsing the head of the electrode (and the head of the ATC temperature probe, if used) in distilled water and then repeating the above steps at least twice more.

If you expect to make conductivity readings using other full-scale ranges, you should repeat this calibration procedure using other standard conductivity solutions of appropriate strength. If you do, General advises performing the above procedure (for a 2-ms full-scale range) first. - Page 11 Fig. 3.
