PLT offs and High altitude comp
In menu 5.10.7 the PLT background can be set. This entered value is subtracted
from all PLT readings. This menu should be handled with care and only used if
the diluent background on PLT is stable and not higher than 10.
The menu 5.10.8 is used whenever the instrument is installed at levels higher than
1500 meter (4500 feet) above MSL (Medium Sea Level).
Scroll down to this line using the arrow keys and set '1' in case the instrument is
located above 1500 meters (4500 feet) MSL.
This setting will only extend some of the washing sequences in the instrument
due to the capacity reduction of the waste (drain) pump when used at high alti-
tudes.
No other instrument specifications will be affected.
Print control blood id:s
This menu prints out a list of defined quality control-blood types. Type [Enter] at
this menu line to print out the list. As quality control-blood is not comparable
with human blood regarding the structure of the WBC differential mainly, certain
discrepancies in the total WBC count and/or differential count might occur
whenever using such fixed cells as a normal sample. Entering the defined ID
numbers as obtained from the list, terminated with a “+” sign (right arrow key),
will instruct the instrument to shift it's discriminator range automatically so that
it fits the specific control-blood see also section Calibration and controls on
page 81, in this manual.
Example of a printout:
Thus; entering one of the above defined control-blood Product-numbers as ID#,
will be shown on the display (only) in clear text as a confirmation that the control-
blood mode was selected. E.g.: 888+ will display “Boule Norm.”, but is stored in
memory as 888+.
777+ Boule Low
888+ Boule Norm
999+ Boule High
