The instrument mixes the tube contents for as long as 15 seconds using a low speed spin.
The float descends from the top of the tube toward the closure end of the tube. This mixes
the blood and reagents in the tube. A countdown displays the time remaining in the cycle.
After mixing is complete, the centrifuge accelerates to high speed to separate and pack
the cell populations into distinct cell bands. A countdown displays the time remaining in
the cycle.
Finally, a series of readings is taken. The messages “Reading Cycle In Progress,” is dis-
played while tests are being performed.
