1. INTRODUCTION
1.1. Intended Use
This hematology analyzer is a fully automated cell counter designed for in vitro
diagnostic use, developed for small clinics and point-of-care lab offices.
1.2. The Instrument
ELite 3 is a fully automated, bench-top hematology cell counter.
It implements the so-called Coulter-method for counting cells passing through a small
aperture, and measures the hemoglobin content of red blood cells.
The analyzer features a color graphical LCD display module with touch screen, and
has a separate START button.
The software allows sending results to an external printer (via USB port), or can have
an optional, 58 mm built-in thermal printer module.
Its internal memory is capable of storing 1000 records with full histograms, and
individual patient data. QC measurements are also stored in separate database. The
software operating the instrument is easy to upgrade using a USB pen-drive. The
instrument allows connecting to a host computer for uploading records stored in the
memory through a USB B (slave) port. Archiving and restoring of records to and from
USB pen-drive is also possible.
NOTE
:
If the equipment is used in a manner different from which the
manufacturer specified, the protection provided by the equipment
may be impaired. Misuse of equipment or use other than its
intended purpose will invalidate conditions of warranty. The
accuracy and precision may also be impaired.

3. MENU SYSTEM
3.1. General Information
This chapter contains information about the structure and usage of the software
implemented menu structure.
This integrated software controls instrument operations including calculation and
evaluation of measured data, displaying results and information screens, storage and
recalling of data.
3.1.1. Navigating in the Menu System
The instrument uses a menu system to initiate actions and to access settings.
Navigate in the menu system by simply touching the LCD at the item you want to
open/activate. From any submenu, the Home button will go back to Main menu, while
Back moves one step back in the menu tree.
3.1.2. Touch screen calibration
In case you experience uncertainties during tapping the touch screen (you tap a
specific location, still the required function key is not being activated) you will have to
calibrate the touch panel.
Tap and gently hold any location on the touch screen. (Make sure not to press it
hard, otherwise you can damage the screen.) After cca 10 seconds, a calibrating
screen appears. Tap the reference points one after another. If you made an error,
you will hear an error beep, and the process restarts.
If the calibration was successful, you will return to the original screen.
