1 - Introduction
Floppy Disk Drive
A floppy disk drive is located on the front of the instrument to enable the instal-
lation of software updates and to copy important data files to floppy disk.
External Ports
Ports on the rear of the instrument allow the user to connect an optional Re-
mote Alarm unit and an optional printer.Two other ports are for Field Service
diagnostic use.
Instrument Calibration
Components of the BACTEC® 9050 instrument are selected and designed to
maintain electrical and optical integrity throughout the product's life.All instru-
ments are calibrated at the factory prior to shipment, and should not require
recalibration during the usable life of the instrument, unless certain components
are replaced. Calibration helps to insure that any fluorescent series medium vial
in any station will have initial and final fluorescent values within a specified range.
1.3 Software
Overview
The system software presents a simplified user interface on the LCD Display,
with picture icons to represent all the functions, operations, setup parameters,
and status conditions (see Section 5 - Reference for charts of all icons). Routine
system operations are performed by pressing the teal soft key that corresponds
to the definition shown on the screen.
There are three basic types of displays:
Main Status Screen - When the instrument door is closed, this screen
appears. It shows the number of vials that are positive, negative, ongo-
ing, available, and stations that are in error or anonymous. Also shown
are the current date and time and the instrument temperature. Soft-
ware keys allow you to configure the setup parameters, review system
errors, or print the System Status Report. See Figure 3.
Configuration Screens -Accessible from the Main Status Screen,the Con-
figuration Screens allow you to set the protocol length, the time and
time format, the date and date format, the audible alarm volume, the
instrument identification number, the DVE (Delayed Vial Entry) thresh-
old (feature not available for use in the USA), to select the desired
language for reports, to write data to a floppy disk, and to update sys-
tem software.
Activity Screens -When the instrument door is opened, software key defi-
nitions appear that enable you to enter new vials, remove positive vials,
remove negative vials, identify anonymous vials, and resolve station er-
ror conditions.
