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 alignment 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. |

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.
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.
NOTE:
This leak tester gauge is designed according to AAMI standards for non-automatic sphygmomanometers to provide precise and accurate readings. As such, this unit incorporates a standard built-in manometer bleed/leak rate which is illustrated by very slight pressure loss and needle movement.
Therefore, to confirm any suspected minor endoscope leaks, perform a stage II, wet leak test and carefully look for the presence of a trail of air bubbles.
4) Carefully observe the gauge pressure to determine if the indicator remains in the GREEN zone. If the indicator drops from the GREEN zone rapidly, a major leak may be indicated.
NOTE:
DO NOT IMMERSE the entire instrument if the gauge indicator does not remain in the GREEN zone. Instead, contact your PENTAX Service Center.
