After the probes are installed, there is a period of time required for each probe to stabili-
ze in its new environment. The conductivity probe will be the fi rst to stabilize, followed by
the temperature probe which requires about 10 to 15 minutes before accurate readings
are possible. The pH and ORP probes will take considerably longer to stabilize. Their rea-
dings are much more sensitive. The pH probe will stabilize in about 24 hours while the ORP
probe may require 48hours.
If the conductivity probe is not installed properly and the probe is exposed to the electri-
cal interference from the pH or the ORP probes, unreliable readings will result both on the
pH/ORP as well as on the Conductivity. Immediately restore a condition where ph/ORP
probes are electrically separated and carefully clean the Conductivity probe in order to
remove the deposits that evenutally have build up on the sensors (even few seconds of
electrical interference can create a deposit on the Conductivity probe).
This can be achieved using the specifi c solution, ELOS CLEAN. Leave the probe inside
the solution for about 30 minutes than, with a soft cloth or very fi ne (#600) grit sandpaper
lightly polish the platinum electrodes.
During normal operation, the frequency required for this cleaning depends on the water
quality. For relatively clean fresh water, this polishing might be required only once per
year.
For saline water, it might be advisable to clean the probe once per week.
