The instrument employs the electronic impedance principle for cell counting and
sizing, and a colorimetric method for measuring hemoglobin. A microprocessor
is used to measure the parameters and to size the cells. During the count the pro-
cessor is checking the analysing process for any irregularities. Size distributions
are printed for all populations (RBC, PLT and WBC).
The instrument has as standard a parallel and a serial output, which is user pro-
grammable. From a built-in selectable program the user can choose between dif-
ferent print formats.
A bar-code reader (scanner), available as an option, can be connected to enter the
sample ID automatically.
The instrument is fully automatic, which means that, the system is always pow-
ered on and performs automatically preforms check- and cleaning cycles to min-
imize user maintenance.
Note:
PCT, LPCR, RDWa and PDWa are not established parameters. Their use should
be restricted to research or investigational use only.
