 Leakage testing with leakage tester (MB-155)
1.
Fill a basin with clean water. Use a basin which is at least 25 (W) × 10 (H) ×
50 (D) cm in size and deep enough to allow the endoscope to be completely
immersed.
Figure 7.9
2.
Insert the leakage tester connector into the output socket of the
maintenance unit (MU-1) or the light source and turn the maintenance unit
or the light source ON. Set the light source airflow switch to “HIGH” or “3”
(see Figure 7.9).
3.
Confirm that the leakage tester is emitting air by gently depressing the pin
located inside the leakage tester’s connector cap.
4.
Attach the leakage tester to the venting connector on the light guide
connector (see Figure 7.9).
5.
With the leakage tester connected, immerse the endoscope in water and
observe for approximately 30 seconds while angulating the bending section.
Confirm that there is no location on the endoscope from which a continuous
series of bubbles emerges.
6.
Remove the endoscope from the basin with the leakage tester attached.
7.
Turn the maintenance unit or the light source OFF.
8.
Disconnect the leakage tester from the maintenance unit or light source.
9.
Wait 30 seconds or until the covering of the bending section contracts to its
pre-expansion size. Disconnect the leakage tester’s connector cap from the
venting connector.
10.
Thoroughly dry the leakage tester.
