3.2.2 Test Flow Instruction
1. Periodic movement sequence of sample reagent probe
a. Switch the pump to zero, internal and external wall rinsing
b.Inhale 3ul air.
c.Rotate to the position above the sample reagent disk
d.Descend till the sample&reagent probe point into liquid level about 2mm
e. Assimilate quantitive volume + push back redundant sample
f.Move to above the rinsing pool from the reagent bottle to rinse the external wall.
g. Inhale 3ul air
h. Move to above the sample&reagent disk
i. Assimilate quantitive volume sample
j.Move to above the reaction disk from sample cup or tube
k.Add sample and reagent into the reaction cuvette
l. Rotate to above the rinsing pool from reaction cuvette
→ (next periodic movement sequence).
2. Stirring rod periodic movement sequence：
a．Rotate to above reaction disk
b．Descend into reaction cuvette
c．Mix reaction liquid
d．Rise from reaction cuvette and rotate to rinsing bath
e．Descend into rinsing bath
f．Stirring rod rinsing
g．Rise from rinsing bath
3. Movement and time sequence of reaction disk
A track includes total 120 reaction cuvettes in reaction disk, and rotates in a fixed way when
testing. The reaction cup always rotates and stops 4 times counterclockwise, total 36＋4＋
82=122 （rotation and stop sequence 36－4－82）patches, in every working period, 15
seconds elapsed.
