5. Troubleshooting and Spare Parts
23
The following table shows the possible causes and solutions of the most
common problems encountered on installations and during maintenance
operations on the probes.
Problem detected Possible cause Solution
Weak signal
No signal from the
probe
Connection cable faulty Replace the cable. See spare parts
Connection cable
incorrectly connected
Check that all connectors are properly
secured. Check that the cables are connected
with the right polarity.
Damaged membrane
(deformed, broken, dirty,
etc.)
Replace the damaged membrane cap and
restore the gel electrolyte. See spare parts.
Dirty or oxidized working
electrode
Remove oxidation with abrasive paper.
Dirty or worn reference
electrode
Rinse carefully using only water and allow to
air dry without the use of cloths or anything
else that would lead to damage to the
chemical coating. If the reference electrode
coating is damaged, contact assistance to
carry out the regeneration.
Contaminated or
depleted gel electrolyte
Replace the gel in the cap with the one
supplied if it is exhausted, see spare parts.
Check the integrity of the reference electrode.
Presence of air bubbles
on the membrane
Replace the gel in the cap with the one
supplied if it is exhausted, see spare parts.
Check the integrity of the reference electrode.
Incorrect calibration of
the instrument where
the probe is connected
Check the working conditions of the probe.
Expired electrolyte gel
Check the expiration date on the package. See
spare parts.
Unstable
measurement
signal
Irregular water flow in
the probe holder
Check the outflow conditions upstream of the
probe holder. Try to regulate the flow by
closing the valve downstream of the probe
holder respecting the flow range.
Defective connection
cable
Cable replacement. See spare parts.
Presence of air bubbles
inside the cap
Eliminate the air bubbles in the gel, add or
replace the gel electrolyte if necessary, and
screw the cap back on.
Currents dispersed in the
water
Check the correct grounding of the system.
Check that there are no sources of
electromagnetic fields near the probe.
