5.1 Conductivity probe cleaning
Over time, nutrient salts build up on the face of
the conductivity probe. This effects conductivity
readings so the face of the probe must to be cleaned
at least once a month.
1. Remove shroud by holding the body and pulling
away the shroud.
2. Using the Bluelab conductivity probe cleaner or an
unscented liquid scourer such as Jif or Soft Scrub
place one or two drops onto the probe face.
3. Using a fi nger or Bluelab chamois, rub fi rmly and
vigorously to clean probe face.
4. Check that water forms an even fi lm across the
surface of the probe. If beading of water is present,
clean again. Beading indicates the presence of oil on
the probe surface. This effects readings.
5. Refi t the shroud and test in 27.7 CF/ 2.77 EC
solution. If reading is out it can be edited in
calibration mode. See page 26 for calibration
information. Always clean probe before calibrating.
