4.2.3. Measurement cycle
Before the start of the measurement cycle the instrument is in ready state (status LED is
green). In this state the sampling needle is in the sampling position: out and down. The Mix
chamber is empty, the WBC chamber contains 5.0 ml of diluent (the wake up process or
previous measurement put it into the chamber and the blank HGB measured with this liquid
used). The RBC chamber contains the last rinsing amount of diluent of the previous
measurement cycle or the standby volume.
The following two flowcharts introduce the entire measurement cycle. One of these
flowcharts describes the fluidic transfers related the needle, the other one the chamber
related activities. The flowcharts has synchronization points where one of them waiting (W)
for the others signal (S).
