4.5 FD (Floating Discriminator)
If the discriminator, between the upper volume of PLT and the lowest volume of
RBC, has been set as floating (see set-up menu) the instrument tries to find a min-
imum on the PLT / RBC curve. At this point, the floating discriminator will be
set. If no minimum can be found between the two limits that have been set in the
“discriminator set-up” menu; the floating discriminator will locate itself on the
limit where the lowest number of cells are found. This is a warning and NOT an
error flag. On low PLT values, where often a non log-fitting PLT curve is found,
this warning might occur frequently.
Usually, with correct settings of the discriminator limits, the PLT parameter is still
measured correctly.
4.6 OF (Offset error HGB)
This error flag is related to the HGB parameter only. During a “Power On” or an
exit from the Stand-by mode the offset voltage in the photometer system is mea-
sured. If the offset limits are violated, this flag is set. The ”OF” flag might also
occur during the installation process. In such case, the analyzer was probably ex-
posed to high temperature changes and condensation may have occurred.
4.7 LO (Low blank level HGB)
This error flag is related to the HGB parameter. During each sample a blank is
measured as a reference, if the blank level is too low in intensity, due to a bad lamp
or a contaminated cuvette, the automatic blank adjustment cannot work reliably.

. The HGB photometer will now perform a
self-adjustment. This process takes ca. 5 minutes.
See
HGB Value Flagged with LO on page 99.
4.8 HI (High blank level HGB)
During each sample a blank is measured as a reference, however if the blank level
is too high in intensity, due to a bad lamp or a previously cleaned cuvette, the au-
tomatic blank adjustment cannot work reliable. How to correct the HGB pho-
tometer See
HGB Value Flagged with HI on page 100.
4.9 NG (Negative HGB)
This error flag is related only to the HGB parameter. During each sample a blank
is measured as a reference, however, if a sample has a lower absorption than the
measured auto-blank; this error flag is set. The reason might be:
a) Heavy fluctuations in stray light.
b) Strongly coloured lyzer-reagent.
c) No diluent or lyzer in the system or air bubbles.
To cancel this error, perform a ‘Prime’ from menu 8.1.
Important
Let the analyzer warm up
ca. 1-2 hours and proceed
with the installation proce-
dure. In case the ‘OF’ flag
persists, HGB values will
be incorrect. Call your au-
thorized service depart-
ment.
