LEAKAGE TESTER INSTRUCTIONS
The leakage test is a simple two (2) stage test of the watertight integrity of the instrument. Air pressure is intro-
duced into the interior of the instrument via a hand pump. The FL-100 scope is then checked for pressure decay
by using a pressure gauge. A secondary visual check is also performed.
DRY TEST, STAGE I
BEFORE IMMERSION, Welch Allyn endoscopes
should be tested for any loss of integrity in their
watertight construction (example: major tear in
accessory/suction channel).
1. Remove the Red ETO Vent Cap from the light
guide. The leakage tester connector and the air
vent on the light guide MUST be completely dry
before connecting the Leakage Tester.
2. Secure the Leakage Tester connector to the air
vent on the scope’s light guide (where the Red
ETO Vent Cap was removed).
3. Confirm that the pressure indicator is at “0”.
NOTE: Make sure the pressure release valve on the
back of the gauge is closed before squeezing the
gauge bulb.
4. Pressurize the scope by pumping the hand bulb
until the indicator on the gauge is in the GREEN
zone (0.16-0.20 kg/cm
2 ).
NOTE: During the leak test procedure, the insertion
tube of the scope should be flexed in various posi-
tions and the distal bending section should be fully
angulated in all directions to confirm the absence of
a leak.
DO NOT pressurize into the RED Danger zone. Doing
so may cause serious damage to the scope (Figure #3).
5. Observe the gauge pressure to determine if the
indicator remains in the GREEN zone. If the indica-
tor drops from the GREEN zone rapidly, a major
Ieak is indicated.
NOTE: NEVER IMMERSE the entire instrument if the
gauge indicator does not remain in the GREEN zone.
Instead, contact your Welch Allyn Service Center.
