WET TEST, STAGE II
After determining that there are no major leaks in Stage I testing, Welch Allyn endoscopes may be immersed in
clean water to test for loss of integrity in the watertight construction.
1. With the Leakage Tester securely attached to the scope and the scope pressurized with the gauge indicator in
the GREEN zone, the entire scope may be immersed in clean water (Figure #5).
NOTE: Only the Leakage Tester connector and a small portion of its tubing should be immersed. NEVER
immerse the entire Leakage Tester.
2. Observe the instrument carefully while deflecting the distal tip of the scope in all directions. A few bubbles
may initially occur from recessed areas of the scope. This is normal. If a continuous stream of bubbles is
observed from the same location, a leak is indicated. DO NOT use the scope! Immediately remove it from
the water (Figure #6).
3. After removing the scope from water, release the air pressure within the scope by opening the pressure
release valve on the handle of the Leakage Tester. After the gauge indicates “zero”, disconnect the Leakage
Tester from the scope.
NOTE: NEVER connect or disconnect the Leakage Tester under water. This will cause leakage of water into the
scope and Leakage Tester. This can cause damage to both instruments.
4. If leakage was discovered, thoroughly dry the instrument and contact your Welch Allyn Service Center.
5. If no leakage was discovered, you may proceed with cleaning and disinfection of the scope as described in
the Owner’s Manual.
