181Appendix: ReplatinizationXL20, 30, 50 and 60 metersReplatinization is the process of replacing the platinum on the surfaces of the 2 cell conductivityprobes that may flake or wear off over time. The platinum on the surface of the probe is used toincrease the surface area of the measuring surface resulting in decreased polarization error.Replatinization is a relatively quick procedure to perform, taking no more than 5 minutes.Although replatinization is not a long process, the replatinization solution is costly. If you are notcertain that replatinization will improve the performance of your accumet conductivity probe,please call the technical support hotline at 1-888-358-4706.To Perform Replatinization1. Access the Replatinization mode from the Mode screen. In any measuring mode, touchMode to access the Mode screen.2. Touch Replat. to enter the Replatinization mode.3. Immerse your 2 cell conductivity probe into the replatinization solution. The immersiondepth should be enough to cover the vent holes on the probe.4. Touch Start on the display screen to begin the process of replatinization. At this time acountdown timer will appear on the display screen showing the time elapse and timeremaining in the replatinization procedure.Note: At anytime after you have initiated the replatinization:You can touch Stop to stop the procedureORYou can touch Exit to cancel the replatinization the procedure and return to the Mode screen.4-cell conductivity probes do not require replatinization.
