(manufactured by Awareness Technology and distributed by companies like Neogen) is a compact, microprocessor-controlled, multi-purpose photometer system. It is widely used in laboratories for reading ELISA microtiter strips or break-apart wells, featuring a user-friendly touch screen, onboard printer, and customizable test programming.
The is a technical document produced by Awareness Technology (formerly Stat Fax). Unlike the user manual, which explains daily operation for lab technicians, the service manual is designed for biomedical engineers, field service technicians, and advanced lab managers.
When diagnosing complex board-level issues, technicians rely on standard voltage references:
Maximize the counts by adjusting the lamp positioning screws until the peak light throughput is achieved. Wavelength / Filter Calibration
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. Dimensions: Approximately stat fax 4700 service manual
While the provides instructions on routine use, the Service Manual (often labeled as a Technical Guide or Service Procedure in documents like those found on Scribd ) provides technical details intended for trained laboratory professionals or authorized technicians. The service literature covers:
: Large non-volatile memory capable of storing up to 120 user-entered test protocols.
Inspect the guide rails of the strip carrier. If movement appears sluggish or noisy, apply a single drop of high-quality, light-grade machine oil or synthetic lubricant recommended by the manufacturer. 3. Optical System Calibration and Verification
The service manual empowers you, but it has limits. Call a certified Awareness Technology service provider if: Unlike the user manual, which explains daily operation
The Stat Fax 4700 is a reliable and versatile workhorse for modern laboratories. The official service manual is an indispensable tool for ensuring its proper operation, from initial setup and daily use to troubleshooting common issues. By understanding the manual's structure and key sections, lab personnel can minimize downtime, perform basic maintenance, and get the most accurate results from their microstrip assays. For any complex repair not covered in the Operator's Manual, it is essential to contact a qualified service technician or the manufacturer's technical support.
Large non-volatile memory that stores 120 user-entered tests. Printer: On-board graphics printer for fast documentation.
Monitor the raw ADC (Analog-to-Digital Converter) counts for the blank channels.
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.

Preventive maintenance (PM) mitigates the risk of sudden mechanical failure and optical drift. Perform these steps at the recommended intervals. Daily Maintenance
To maintain high-quality diagnostic data, the following tasks should be performed regularly, as detailed in the service manual: 1. Lamp Replacement Stat Fax 4700
Blown lamp, degraded filament, or misaligned optical path.
