Performing the leakage test
100
• During leakage testing, a continuous series of bubbles
emerging from a location on the endoscope indicates a leak
at that location. This means that water will be able to
penetrate the inside of the endoscope. If you locate a leak,
remove the endoscope from the water and contact Olympus.
• Never connect or disconnect the water-resistant cap or the
leakage tester's connector cap while immersed. Doing so
could allow water to enter the endoscope and equipment
damage can result.
• Rotate the leakage tester's connector cap until it stops. If it is
not fully and properly attached, the endoscope's interior will
not be pressurized and accurate leakage testing will be
impossible.
• When connecting the leakage tester's connector cap to the
water-resistant cap's venting connector, make sure that the
inside of the leakage tester's connector cap and the outside
of the water-resistant cap's venting connector are completely
wiped and dry. Water remaining on either component may
penetrate the inside of the water-resistant cap and could
cause endoscope malfunction.
• Always disconnect the leakage tester connector from the
light source or maintenance unit before disconnecting the
leakage tester's connector cap from the venting connector.
Failure to do this will not allow the endoscope to
depressurize properly. This may damage the endoscope.
• Do not perform leakage testing with the endoscope
immersed in detergent. The bubbles present in detergent
may prevent observation of a leak.
When the leakage tester connector is in place, the covering
of the bending section will expand as the air pressure inside
the endoscope increases. This is normal.

Fill a basin with clean water. Use a basin that is at least 40 cm by 40 cm (16"
by 16") in size and deep enough to allow the endoscope to be completely
immersed.
