Setup Procedures: 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.
After completion of a successful self-test routine, the monitor is ready for use.
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.

Test Description
170 Series Monitor
What to Verify
Ensure all indicators and each segment of the displays
illuminate throughout the entire self-test routine.
Make sure the monitor performs the recorder test. If
there is a problem with the internal circuitry, the recorder
test will not be performed.
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.
