Routine Maintenance
Regular maintenance of the equipment ensures maximum longevity. A thorough visual inspection
must be carried out regularly and any damaged part must be replaced.
Deposits such as biofilm (or silt), silt and mud must be carefully removed.
Use a sponge with warm soapy water (such as dishwashing liquid) to clean the body
of the probe and in particular at the level of the locking rings of the caps and
sensors. Never use abrasive agents (eg a scouring pad).
In case of heavy contamination with barnacles (or calcifying organisms), rinsing with water may not
be sufficient. Depending on the degree of contamination, we recommend removing the
heaviest contamination with a plastic scraper. Then use a soft sponge with a 5% acetic
acid solution (white vinegar), preferably with warm water, and rinse the sensor with
fresh water.
Wipe and dry the sensor with a soft cloth or optical wipes.
4.1.1
O-rings service
The O-rings seal the probe. Any O-rings damaged can affect the reliability of the sonde. A visual
inspection must be done each time a sensor is plugged or unplugged and also when battery
compartment is opened. Check that no hair-type, particle-like elements are found on the O-rings. If
the surface has impurities, gently clean them with a non-fluffy wipe and lightly grease the O-rings
with molykote grease. Any damaged O-rings must be changed.
4.1.2
Sensor port service
A sensor should
ALWAYS
be unplugged WiMo's head downwards in order to avoid any water
entering the sonde.
During each plug/unplug sensor operation, do a careful inspection of the surfaces of the sensor
location. Check that there are no scratches, no particles or impurities lodged on these surfaces.
Prefer compressed air for cleaning location to avoid scratching by using a wipe or other.
Check that the location is dry before repositioning a sensor on the location.
