CELL-DYN 3000 System Operator’s Manual 3-1
9140240E — May 1995
Chapter 3
Principles of Operation
Overview
The principles that the CELL-DYN® 3000 uses to measure, count, and
calculate the hematologic parameters are discussed generally in the first
section of this chapter. The parameters will be discussed individually and
a detailed explanation of the theory used for parameter derivation in each
of the three methods will be given in the last section.
The three independent measurement channels used in the
CELL-DYN 3000 are:
• The optical channel for determining the WBC count and
differential data
• The impedance channel for determining the RBC and PLT data
• The Hemoglobin channel for determining the HGB data
During each instrument cycle, the sample is aspirated, diluted and mixed,
and the measurements for each parameter are performed.
