3 . Mechanical Parts Check
After the temperature and pressure/vacuum checks are completed, the following
functions will be checked.
• Sampling valve operation
• Whole blood aspiration motor and sheath motor operation
• Whole blood manual aspiration pipette rinsing
4 . Background Check
After the mechanical parts check is completed, the message "Auto Rinse" appears.
After an auto rinse cycle is completed, the background values are checked. If the
background values are less than or equal to those shown in the table below, the
background check is complete.
Table 2-3: Acceptable Background Limits

If any of the limits are exceeded, the background check is repeated again. A
maximum of two additional rinse cycles will be performed. If any parameter
exceeds the acceptable limit in both the second and third checks, the background
check stops, the message "Background Error" appears with the corresponding
parameter name, and the alarm sounds.
NOTE: The parameter which the background data exceeded the
acceptable limit is shown in the Status Display. Press [Status]
keypad in the root menu.
In the case of a background error, analysis can be performed; however, the
measured values may be somewhat high. Press [More] key to display the
[Auto Rinse] key. Press the [Auto Rinse] key to perform a background check
again. If the parameters are still not within the acceptable range, see Chapter 8,
Troubleshooting.
