First, the screw collar must be loosened and removed so that the tip of the
probe can be separated from the main body.
The three channels in the tip of the probe can be cleaned using thin nylon
threads. Insert the thread into each of the channels in turn, from the base,
and push through until it can be pulled out from the top.
Having cleaned the channels thoroughly, the tip of the probe must be
refitted. Offer the tip of the probe to the main body, being careful to align
the guide pin A presented by the body with the hole B located in the tip, as
illustrated in the figure below. Retighten the screw collar.
Clean the outer surface using a lint-free soft cloth moistened with water and
mild detergent; if the probe is to be sanitized, moisten the cloth with a 3%
solution of hydrogen peroxide.
