3.2.3 TEST-Button
This button allows you to run a 4-step user initiated Device Test
program to identify whether the LSU operates satisfactorily, is assembled
correctly or if it needs service:
- STEP 1 - Checking for occlusions in the Suction System (including
canister and tubing).
- STEP 2 - Checking the vacuum build-up efficacy of the Pump System.
- STEP 3 - Checking the max. achievable vacuum level of the LSU. (reaches
this level within 10 seconds).
- STEP 4 - Checking for air leakage in the Pump System (including canister
and tubing).
To indicate that the LSU is in test mode, the Power ON Indicator
will flash rapidly (approx. twice per second) until you exit the test
program.
BEFORE YOU START THE DEVICE TEST
- Before you press the TEST-Button, make sure the Patient Suction Tubing
is not occluded or bent.
DEVICE TEST DESCRIPTION
- Press and hold the TEST-Button while setting the Operating Knob to
500+ mmHg.
Note:
Do not release the TEST-Button until min. 2 seconds after the
Operating Knob has been set to 500+ mmHg. The test will start immediately.
- As soon as LED 2 of the Battery Status
Indicator comes on (takes approx. one
second) fully occlude the Patient
Suction Tubing.*
- Keep the tubing occluded until LED 1
comes on. To read the test results
see next page.
Note:
If you need to interrupt the test and revert to normal operation, turn the
Operating Knob to another position and then select the required setting.
* If the tubing is not occluded within 2 minutes, the test will be interrupted and
the Power ON Indicator will start to flash slowly (approx. once per second).
