The PENTAX Leak Tester allows for a simple two (2) stage testing of the
watertight integrity of PENTAX Endoscopes. Air pressure is delivered by
means of a hand operated bulb, eliminating the need for any electrome-
chanical devices.
DRY TEST, STAGE I
BEFORE IMMERSION, PENTAX Endoscopes should be tested for any
major loss of integrity in their watertight construction (example: major tear
in the working channel).
1) Secure the Leak Tester connector to the air vent on the scope
light guide. A soaking cap should be securely connected and
covering the electrical contacts of the light guide plug. The Leak
Tester connector and the air vent on the scope light guide MUST
be dry before connecting. Proper connection will require align-
ment of the air vent pin and clockwise rotation of the Leak Tester
connector.
2) Make sure that the pressure release trigger is in the “OUT” or
“PUMP” position.
3) Pressurize the scope by pumping the hand bulb until the indica-
tor (needle) on the gauge is in the GREEN zone. DO NOT pres-
surize into the RED zone as it may cause serious damage to the
scope.
Align the needle with one of the incremental pressure markings
(reference lines) in the Green one. It will be easier to notice any
minor leak with slow needle movement if the needle is lined up
with a point of reference.
4) Carefully observe the gauge pressure to determine if the indica-
tor remains in the GREEN zone. If the indicator drops from the
GREEN zone rapidly, a major leak may be indicated.
NOTE:
During the leak test procedure, the insertion tube of the scope
should be flexed in various positions and the distal bending section
should be fully angulated in a all directions to confirm the absence
of a leak.
NOTE:
This leak tester gauge is designed according to AAMI standards for
non-automatic sphygmomanometers to provide precise and accu-
rate readings. As such, this unit incorporates a standard built-in
manometer bleed/leak rate which is illustrated by very slight pres-
sure loss and needle movement.
Therefore, to confirm any suspected minor endoscope leaks, per-
form a stage II, wet leak test and carefully look for the presence of a
trail of air bubbles.
NOTE:
DO NOT IMMERSE the entire instrument if the gauge indicator does
not remain in the GREEN zone. Instead, contact your PENTAX Ser-
vice Center.
