9. Cleaning System:
Purpose: Clean the inside and outside of sampling
probe
Cleaning trough: It’s left side is used for cleaning the
inside of sampling probe, and its right side is used for
cleaning the outside of sampling probe.
Wash bottle: it is used for holding distilled or
de-ionized water.
Waste bottle: it is used for holding waste liquid.

12. Mechanic Arm Module:
It has two arm units, which apply for XYZ 3D movement
Sampling arm unit ：
To make the sample probe move so as to add sample and reagent into
cuvette , and have exploration for automatic liquid level and longitudinal anti-
collision performance and heating for sample reagent.
Catcher arm unit ：
To grab cuvette from make-up place, incubation place and test place to
specified place to add up sample or reagent or make test or discard cuvette into
waste box after test; it also has even agitation performance with reaction liquid
and exploration for cuvette.

inner wall and outer wall.
at a constant pressure of
280mmHg±30mmHg
Drain liquid path
Vacuum pump sucks waste liquid bottle
and creates negative pressure gap and
drain waste liquid from washing slot into
waste liquid bottle.

28. Instrument installation
1, Instrument shielding
cover is plastic part, so it
can't bear outer force.
2. when installing, after
open the shielding cover,
please use the diagnonal
plier to cut the string
ribbon on the sampling
probe carrier, and catcher
carrier. There are five
string ribbons in total.

29. Instrument Maintenance
• Users should periodically clean and maintain the sampling needle and mechanical rail.
• Daily Maintenance
– The used cuvettes should be discarded.
– Disposal of waste fluid
– Wipe away the residual liquid on the reagent holder.
– Clean the sample/reagent needle.
• Weekly Maintenance
– Pipe cleaning
– Equipment cleaning
• Monthly Maintenance
– LED calibration
– Clean the powder or debris on the test hole and incubation hole.
• Quarterly Maintenance (three to six months)
– To maintain the machinery rail, clean the stain/dust, and then spray/coat with
special grease.
– Clean the interior of lotion bottle, and clean the filter on the outlet pipe of lotion
bottle for one time.
– Calibrate the mechanical position
