Service manual
The optical system continues to work when the general cover of the analyzer is open, whereby the analyzer can continue
to take readings while the user handles, for example, the sample tubes or the reagent bottles. The rotor cover must be in
place for the optical system to work correctly. A detector tells the analyzer of the presence of the cover. The analyzer
aborts the readings if the user removes the rotor cover while the optical system is taking photometric measurements. If
the rotor is not covered, the analyzer 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 components are controlled by an electronic system based on a microprocessor.The microprocessor has
two external communication channels that make it possible to link up the instrument to the computer containing the
application program and to an optional external module for measuring ion concentration. The electronic system is made
up of the following independent boards:
- Microprocessor board
- Photometric system board
- Needle conditioning board
- Racks detection board
- Front indicator board
- Power supply board
- Communications board
1.1.5. Application program
The application program makes it possible to control all the operations of the analyzer. From 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, configure 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
functioning of the user program. For detailed information to this regard, please consult the User’s Manual included with
the analyzer.
