Diagnostics; M Valve Function - Bayer HealthCare RapidPoint 400 Series Service Manual

Diagnostics

This Section describes how to print diagnostic reports, how to copy
diagnostic data to a diskette, and how to use the diagnostic tests to
evaluate the function of certain components of the Rapidpoint 400 series
systems. You can print diagnostic reports that provide information about
the performance of the measurement channels, the sensors, the printer,
and the temperature control system. You can also perform diagnostic tests
that evaluate the performance of the valve and the sample and wash
pumps.
Only Bayer Diagnostics service representatives can access the diagnostic
tests. Step-by-step procedures guide you through each test.
Before removing the measurement cartridge, ensure that any
CAUTION:
tests not requiring removal of the measurement cartridge are performed.
Once a measurement cartridge is removed, if reinstalled it is likely to fail
within a few days. To verify repairs, you may reinstall the measurement
cartridge while remaining in Diagnostics. A new cartridge must be installed
before leaving the customer site.
