A detector tells the analyser of the presence of the cover. The analyser aborts the readi ngs if the user removes the
rotor cover while the optical system is taking photometric measurements. If the rotor is not covered, the analyser
informs the user so that he or she places the rotor cover when it sends samples to be analyzed.
1.1.4. Electronic system
The described elements are controlled by an electronic system based on a micropro cessor. The microprocessor has
two exter nal communication channels to connect the instrument to the computer containing the application pro gram.
The electronic system is made up of the following independent boards:
- Microprocessor board
- Photometric system board
- Needle conditioning board
- Fluid system interconnection board
- Arm interconnection board
- Rotor interconnection board
- Power supply board
1.1.5. Application program
The application program makes it possible to control all the operations of the analy zer. Fro m this program, the user
can monitor the state of the analyzer and the work session, program parameters, e.g. technique parameters, prepare
the work session, prepare results reports, congure different analyzer options, activate various test utilities, prepare
and maintain the instrument and carry out internal quality control processes. The purpose of this manual is not to
explain the fun ction ing of the user program. For detailed information to this re gard, please con sult the User Manual
included with the analyzer.
1.2. FUNCTIONING OF THE ANALYSER
The A15 analyser is an automatic random access analyser specially designed for performing biochemical and turbi-
dimetric clinical analyses. The analyser performs patient-by-patient analyses and enables the continual introduction
of samples. The analyser is controlled from a dedicated PC that is permanently com muni cated to the instrument.
The programme, installed on the computer, keeps the user constantly informed of the status of the analyser and the
progress of the analyses. As results are obtained, the com pu ter shows them to the user immediately.
When a Work Session is begun, the ana ly ser proposes performing the blanks, calibra tors and controls programmed
