5.4. Leakage Current Tests

Leakage current test is required after replacing the spare parts. When testing Applied Part Leakage Current, an Ambu
visualization device shall be inserted, since the visualization device is the applied part.
In order to be able to measure applied part leakage current, use metal foil wrapped around the distal tip of the
visualization device (See Figure 35).

5.5. Functional Tests

Run any of the following functional tests relevant for the spare part replaced.
Image Display and Visualization Device Connector Test
After the displaying unit has been re-assembled, always perform a test of the image to check if the replaced parts and the
whole system works as expected.
a) Turn the displaying unit ON
b) Connect a visualization device and point the distal end of the visualization device towards an object, e.g. the palm of
your hand.
c) Verify that a live video image appears on the screen
d) Make sure that the live image has the correct orientation
e) Check that there are no lines or other unexpected disruptions in the image
f ) Check that there is light in the visualization device LED
g) Repeat steps II-VI for each of the visualization device connectors
h) Verify the touch function by touching some of the options on the screen.
Battery Check
Check that the battery discharges as expected.
a) Connect the power supply and charge the displaying unit until the battery is fully charged
b) Disconnect the power supply
c) Wait for the screen saver to be activated (as this will change the expected remaining battery time)
d) After 10 minutes check the time in the battery icon.
If the battery remaining time decreases as expected ± 20%, the test is passed (e.g. battery remaining time goes from 4:10
to anywhere between 3:58 to 4:02 in 10 min.).
Fan Check
a) Turn off the displaying unit.
b) When turning on the unit, check if the fan starts rotating silently by looking through the ventilation ribs and listening
for any noise.
