Perform Leak Test Procedure
The leakage test allows for a simple two stage test of the water tight
integrity of the instrument. Air pressure is introduced into the interior
of the instrument by means of a hand pump. The instrument is then
checked for pressure decay via a gauge and then visually.
Leakage Tester
Stage-One Test
BEFORE IMMERSION, the instrument should be tested for any major loss of
integrity in its watertight construction (example: major tear in the bending
section).
1. Secure the Leakage Tester to
the ETO vent connector on the
instrument’s endoscope connector
terminal. The Leakage Tester
connector and the ETO vent
connector MUST be dry before
securing. Proper connection will
require alignment of the air vent
pin and clockwise rotation.
2. Turn the gauge faceplate to “zero” on
the pressure indicator.
