1. Introduction
1.1 Applications
1.1.1 Intended Use
The Stat Fax®4700 is a compact, microprocessor-controlled, multi-purpose photometer
system designed to read and calculate the results of assays, which are read in microtiter
strips or break apart wells.
The Stat Fax®4700 may be used for in-vitro diagnostic testing. It is a user-programmable
open system with selectable strip formatting, alphanumeric test naming, automatic
interpretation options, duplicate well options, curve plotting and editing, and flags and error
messages.
It is a general purpose instrument intended to be used by trained laboratory professionals
who are capable of selecting the appropriate features and options for each specific clinical
application. Contact your company’s instrument service provider to arrange for training if the
information in this manual is not sufficient.
FOR IN-VITRO DIAGNOSTIC USE
POUR L'USAGE DIAGNOSTIQUE IN VITRO
1.1.2 Summary of the Instrument
The Stat Fax®4700 is specifically designed for bichromatic absorbance reading, however it
is also capable of monochromatic reading using four standard filters (405, 450, 492, and 630
nm) Special models are available with either six VIS (405, 450, 492, 545, 600, and 630 nm)
or six UV (340, 405, 450, 492, 545, and 630 nm). Alternate filters are available from 340 to
700 nm.
This instrument is programmed with many keypad-selectable general purpose programs.
Each mode is self-prompting, to reduce error and simplify operation. The general purpose
programs include relative light unit, multi-point linear and log-logit regressions, and point-to-
point connections.
These calculation modes have been selected to facilitate the performance of Elisa
immunoassays.
Convenience features include automatic blanking options, the ability to indicate the locations
of positive and negative controls, and to enter control acceptance criteria for automatic
comparisons, to select positive and negative interpretations based on concentration value,
and to edit out discrepant duplicates with automatic re-calculation. In addition, user-
programmable memory allows the operator to store test protocols, recall tests by number,
and delete unwanted tests from a user-generated test menu. Instructions for each of these
modes and convenience features are provided in this manual.
Besides quick, accurate, and reproducible results, the instrument offers maintenance-free
and easy operation, versatility, and economy. A stable, factory-calibrated durable design
assures the reliability of the instrument.

2 Stat Fax®4700 Operator’s Manual Doc. 4700 Rev. G
Summary of the Instrument (Continued)
The Auto-Track feature enables all three strips to be read automatically, rather than having
to read each strip individually. The Stat Fax®4700 uses a specialized strip carrier. Be sure
to use only this carrier. Starting from Position A (home position), the Auto-track feature
transports the carrier such that all of the wells in all strips in the carrier are read; user is
prompted to place the carrier into position by changing the background color and emitting a
sound.
•Features
Store up to 120 tests Starting from the home position, the Auto-track feature transports
the carrier such that all of the wells in all strips in the carrier are read; sounds and
colorful displays guide the user. Transmit and capture data via USB to PC connectivity
using SF_Capture software (see External Output section).
Pre-programmed Modes
In addition to reading absorbance, this instrument can be programmed to calculate
concentrations based on stored formulas using absorbance readings of one or more
calibrators. The basic calculations are permanently stored in memory and include
several single and multi-point equations. Provisions are made in certain cases for
reading specimens in duplicate and/or using the mean reading in calculations. Each
calculation mode is described in detail in Section 2.5-Modes of Operation. The following
calculation modes are offered: Single point calibration by standard or factor, multi-point
calibration with point-to-point curve fit, linear regressions with log, linear, and log-logit
selections, cubic spline and cutoff mode selections.
User-programmable Memory
The instrument’s software allows the operator to create, edit and store a menu of assay
programs. Standard curves are also stored in this memory. Test protocols remain
stored until either changed or deleted by the user.
1.1.3 Principles of Operation
The strip carrier precisely positions each well into the optical path for reading. Light energy
from a lamp is focused by an integral lens, directed through an aperture, and then passed
vertically through the sample. A wheel below the sample positions the filters so that
readings can be taken very quickly at both the operating and differential wavelengths.
(Using bichromatic differential absorbance values improves precision by correcting for
optical imperfections in the plastic wells and removes the effects of meniscus and turbidity.)
A photo detector converts transmitted light energy into electrical signals, which are amplified
and interpreted.

1.6.1 Strip Carrier Loading and Positioning
The Strip Format must be selected before programming a new assay. Use the instructions
from the table that follows to set the strip format, load, and properly position the strip carrier
into the instrument. Place the carrier in the instrument as instructed; for proper alignment
utilize the alignment arrow located inside the cover of the instrument (Figure 1.6.1-2).
Figure 1.6.1-1 Strip Carrier
To format an 8 well (A-H) or 12 well strip type:
from the Settings menu, select the ‘Strip
Format’ option. 8 and 12 well strip types will
display. Make a selection and press Save. The
printer will print out the enabled strip format.
Ensure that the wells are pushed down and
seated firmly into the tray so that they will not
cause the plate to jam on entry. Use care that
well tabs do not extend over other wells. Use
caution when attaching labels so they do not
jam in reader or interfere with read path. Be
sure to place the tabbed strip ends at the back
of the carrier, well position 8 or 12.
Before installing the strip carrier, note the
location of the lead pin and groove on the
carrier; note the location of the alignment
arrow inside the cover of the instrument
(Figure 1.6.1-2).
WARNING: To prevent sample mis-
identification, use care when placing strips and
wells into the strip carrier. Ensure the strips
are not reversed so that the last patient ID is
not read first. Wells are read in the direction in
which they are loaded.
Figure 1.6.1-2 Strip Carrier with Well A1 in
position
CAUTION: Place the end of the strip carrier with
the lead pin into the instrument first and place
the groove over the groove bar. Slide the carrier
into position all the way to left side so that
position A1 on the strip is aligned with the
instrument’s alignment arrow (Figure 1.6.1-2).
