7.2 Calibration

8
Scroll through parameter screens by using the [NEXT] button and
verify that the CVs for the following parameters are within the stated
limits:
Parameter
OT/CT CV%
MPA/PD CV%
RBC
< 2.2
< 3.2
MCV
< 1.8
< 1.8
PLT
< 5.8
< 6.2
HGB
< 1.8
< 2.9
WBC
< 4.2
< 4.8
MPV
< 4.0
< 4.0
*CV limits are wider on the MPA/Pre-dilute calibration due to differences
in pipetting and blood collection techniques at the operator level.
9
If CV values are not within range operator will be unable to perform
calibration. (Analyses with system information indicators will
automatically inactivate that analysis from the CV calculation and
depending on flag may not be stored on list at all.) If a known sample
handling error or erroneous result is present, then sample can be
inactivated by pressing button to the left of that particular analysis
and changing to empty brackets [ ].
10
If all parameters have acceptable CVs proceed to next step, if not
rerun calibration following steps above.
11
The new calibration factor can be entered in three ways.
The recommended method is to select the [USE CAL] button
which will automatically calculated the new calibration factor
using target range from assay values.
The second method, if no calibrator is available, is to perform
Steps 4-9 using a sample with target values from an assay sheet or
determining target values using a reference analyzer or a
microscope method with an in-house sample. The target values
can be entered selecting the [SET TARGET VALUE] button and
manually entering in the values.
The third method is to manually calculate and enter in calibration
factor. This method should only be used with instruction from
local distributor or authorized service technician.
12
In the first and second methods the calibration factor is automatically
calculated once either the [USE CAL] button is pressed or target
value is entered.
13
Once calibration factor has been entered using one of the methods
above, operator will be prompted to enter a 4-digit Operator ID
(Operator ID is recommended for in-house records of calibration
operator but not required) and an Authorization Code (REQUIRED)
before the new value can be changed or updated.
Note
Authorization Code prompt is displayed only once per calibration
sequence when [USE CAL], [TARGET VALUE], or [NEW CAL
FACTOR] buttons are pressed.
