3. Remove the jumper, then wait for approximately 60 seconds to allow the sensor checks (zero, reference, contamination)
to run.
When the checks are complete, the health/alarm LED will either turn GREEN (tests passed) or RED (one or more
tests failed).
4. If a sensor check fails (red LED), it is recommended to clean the instrument thoroughly in the first instance
(see section 9.4.1 on page 29), then rerun the checks to confirm that sensor operation is normal.
If the problem persists (checks failing repeatedly, health LED is permanently red), please contact Goyen | Mecair
or our local representative.
