Setup Procedures: Monitor Self-Test Routines
Monitor Self-Test Routines
NOTE:
Ensure paper is installed in the
recorder in order to verify a successful
recorder test.
Each 170 Series Monitor contains a self-test routine which checks the internal
circuitry of the monitor, the displays and indicators, and the strip chart recorder.
The self-test routine is automatically initiated each time you turn on the monitor.
CAUTION
SELF-TEST FAILURE—If there is any problem with the self-test
routine, turn off the monitor and remove it from operation. Notify
your Biomedical Engineering Department or Service
Representative.
NOTE:
If the recorder was off at the
time the monitor was turned off, the test
routine will turn the recorder on, then
turn it off after the tests are complete. If
the recorder was on at the time the
monitor was turned off, the tests will be
performed and the recorder will remain
on.
After completion of a successful self-test routine, the monitor is ready for use.
Table 4-1. Summary of Self-Test Routines
Test Description What to Verify
Display/Indicator Test: All displays and indicators
illuminate.
Ensure all indicators and each segment of the displays
illuminate throughout the entire self-test routine.
Internal Test: The internal circuitry of the monitor is
verified.
Make sure the monitor performs the recorder test. If
there is a problem with the internal circuitry, the recorder
test will not be performed.
Recorder Test: The following message prints on the
strip chart paper: TEST: ARE ALL DOTS PRINTED?
Three continuous lines are drawn across the strip chart
recorder paper, testing the integrity of the printhead.
See Figure -. Ensure that the lines are printed in the correct positions
on the paper. Verify that the lines are continuous and no
gaps appear on the traces.
