1. INTRODUCTION
The A25 analyzer is an automatic random access analyzer specially designed for performing biochemical and turbidimetric
clinical analyses. The instrument is controlled on-line in real time from an external dedicated PC.
In each of the components of the A25 analyzer, BioSystems has used leading edge technology to obtain optimum
analytical performance, as well as taking into account economy, robustness, easy use and maintenance. A three-axis
Cartesian operating arm prepares the reactions. Dispensing is performed by means of a pump with a ceramic piston via
a detachable thermostatised needle with Fuzzy Logic control. A washing station guarantees that the needle is kept
perfectly clean throughout the process. The reactions take place in a thermostatised rotor in which absorbance readings
are taken directly by means of an integrated optical system.
This manual contains the information required for learning about, maintaining and repairing the A25 automatic analyzer.
It should be used by the Technical Service as a learning and consultation document for the maintenance and repair of the
instrument. Chapter 2 describes the different mechanical components that form the analyzer together with their functionality,
and chapter 3 describes the electronic system. Chapter 4 describes the Service Program. All the adjustments and
checks of the analyzer are carried out through this program, which is independent from the application program (User
Program). The separation of both programs enable it to be maintained separately and the extensions and improvements
of one do not affect the other. The user does not have the service program. The Technical Service must install it on the
user’s computer in order to carry out the service requirements. Once said tasks have been carried out, the Technical
Service must uninstall the program. Chapter 5 offers instructions for the different maintenance, repair and cleaning
operations that can be carried out by the Technical Service. The annexes contain a summary of the technical specifications
of the analyzer, the adjustment margin tables, the lists of accessories and spares, a list of software versions and their
compatibility and a software troubleshooting guide.
1.1. GENERAL DESCRIPTION OF THE ANALYZER
The A25 analyzer is made up of three basic components: the operating arm, the dispensing system and the reading and
reactions rotor. The electronic system of the instrument controls said components and communicates with the external
