banana plugs are no longer visible. This will ensure a good electrical connection
and prevent fouling of the connections.
5.
Tighten the thumbscrew to secure sensor.
3.1.3 Standard Cleaning Procedure
With some particles, cleaning is easily accomplished by rinsing with tap water. Others
(especially cationic particles) are tenacious and must be removed with fairly vigorous
cleaning. The following cleaning procedure will assure that the CCA is providing
accurate, reproducible measurements.
1.
Remove the sensor and piston according to the procedure outlined above. Remove
the plug and O-ring from the bottom of the sensor.
2.
Scrub the surface of the piston and cylinder, (both inside and outside) with a stiff
nylon test tube brush and a mild abrasive cleanser (e.g. Comet). Use room
temperature tap water.
Avoid water contact with the banana plugs.
3.
Rinse all of the surfaces thoroughly with tap water, ensuring that they are free of
soap film and any residue. Carefully inspect the inner surface of the cylinder to
ensure that no visible particulate matter is left on the surfaces.
4.
Completely dry the sensor, piston and plug with compressed instrument air or by
allowing the components to air-dry in the laboratory.
5.
Return the plug and O-ring to the base of the sensor. Omitting the O-ring will cause
variations in the SCV.
Distilled or de-ionized water may be used. However, the water’s low
conductivity will magnify the SCV. Thus, the operator must ensure that all surfaces
are completely dry before use.
