The Awareness Technology Stat Fax 4700 is a highly reliable, compact microstrip reader used globally in clinical and research laboratories. While it is designed for durability, maintaining accurate diagnostic results requires strict adherence to technical service protocols, routine calibrations, and targeted troubleshooting.
The most common service part required is the instrument lamp. These are available from specialized suppliers. For more complex repairs beyond lamp replacement, the manual advises contacting technical support, as many service functions in the Utilities menu are passcode-protected.
Disconnect the main power cable before performing fuse replacements or internal board repairs.
Section 2.6 of the manual provides critical guidance on setting up the instrument, which is essential for anyone consulting the manual for the first time. stat fax 4700 service manual
High-sensitivity silicon photodiodes translate light transmittance into electrical signals. Electronic Control Board
Inspect the light path wells for dust, condensation, or reagent spillage. Clean gently using a dry, lint-free microfiber swab.
Loosen the lamp bracket screws slightly and adjust the positioning until the beam is perfectly centered over the optical path. Step 2: Filter Wheel Validation The Awareness Technology Stat Fax 4700 is a
Loosen the retaining screws securing the lamp wires to the terminal block.
To verify linearity, laboratories must run certified reference strips (NIST-traceable calibration plates). If the optical density (OD) readings deviate outside the manual's specified tolerances (typically

The service manual outlines how to verify the internal filter wheel. By using a certified calibration plate (with known optical density values at 405nm, 450nm, etc.), the technician verifies that the photometer's readings match the certified values within the permitted tolerance limit (typically ±0.005plus or minus 0.005 5.
