1.6.6.2 Use of the flexible sniffer tip
In addition to the rigid sniffer tip included with the HLD5000, also a 400 mm long
flexible tip (Cat. No. 511-024) may be used. By correspondingly bending the flexible
tip, areas which are hard to access can be reached.
1.6.6.3 Use of the sniffer tip extension
For the purpose of measuring refrigerant concentrations (e.g. in the case of already
packaged test objects in the package), for reaching points which are difficult to
access or for finding large leaks quickly a flexible extension (Cat. No. 511-020) may
be screwed onto the filter holder (see Fig.
Fig. 1-3 /5). Make sure that the plastic hose
surrounds holder and filter holder. The 400 mm long extension ( Fig. 1-3 /6) may be
pulled out after pressing down the ring of the holder ( Fig. 1-3 /8); if required, you can
cut the extension down to the required length. The tip facing the test object must
always be cut at an angle of approximately 45°.
1.6.6.4 Use of water protection tip
In order to avoid sucking in liquids, the water protection tip ( Fig. 1-3 /7) (Cat. No. 511-
025) may be screwed onto the filter holder. The water protection tip will prevent
liquids in up to about 3 mm in height (the e.g. puddles of condensed water) from
being sucked.
