The heart of the Stat Fax 4700 is its optical system, and the service manual dedicates significant detail to this area. It provides comprehensive specifications for the eight-channel fiber optic system, which reads an entire 96-well plate in seconds. Critically, the manual includes the optical path diagram, alignment procedures for the light source (typically a halogen lamp), and the expected voltage and current values at various test points. For the photodetectors, it details the signal-to-noise ratio thresholds and the calibration routine for the analog-to-digital converters. Without this information, a technician would be unable to diagnose common issues such as inconsistent well readings, excessive well-to-well variability, or complete loss of signal.
The Awareness Technology Stat Fax 4700 is a highly reliable microstrip reader used in clinical and research laboratories worldwide. To maintain its accuracy, prolong its lifespan, and ensure compliance with laboratory standards, access to and understanding of the service manual is critical.

is programmed to detect errors and report them on the screen. Error Issue Potential Cause Action from Service Manual Obstruction or failure of transport motor/sensor Check transport path for debris; calibrate home sensor. Lamp Error Lamp filament burned out or low voltage Replace halogen lamp and check lamp housing. Filter Error Filter wheel stuck or misaligned Clean or replace filter wheel encoder. Calculation Error Invalid curve points or low absorbance Recalculate or re-run the assay standards. 5. Technical Specifications for Service When servicing the , ensure the following specs are maintained: Linear Range: 0.0 to 3.0 Absorbance units. Photometric Accuracy: or better.
