Replatinization is the process of replacing the platinum on the

surfaces of the 2-cell conductivity probes that may flake or wear off

over time. The platinum on the surface of the probe is used to

increase 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 in most cases.

This meter is capable of performing replatinization from 1 to 30

minutes. Although replatinization is not a long process, the

replatinization solution is costly. If you are not certain that

replatinization will improve the performance of your conductivity

probe, please call the technical support hotline.

To Perform Replatinization

1. Access the Perform Replatinization screen from the conductivity

Setup screen. The current replatinization time is displayed on the

screen.

2. Touch clear to delete the current replatinization time.

3. Use the keypad to enter the desired replatinization time.

4. Touch enter to accept the replatinization time.

5. Touch START on the display screen to begin the process of

replatinization. At this time a countdown timer will appear on the

display screen to let you know how much time is remaining in the

replatinization procedure. At anytime after you have initiated the

replatinization, you can touch STOP to abort the procedure and

return to the conductivity Setup screen.

Touch exit on the display screen to cancel the replatinization

process and return to the Conductivity Setup screen.

Touch EXIT to return to the Conductivity Setup screen, without

performing replatinization.



4-cell conductivity probes do not require replatinization.
