Calibration & Diagnostic Software

Intuitive setup, calibration and servicing are provided using the AFS “SparroWatch” PC interface software.  This flexible tool presents sensor values and operational data, as well as an easy way to modify calibration variables.  To record momentary behaviour during transients, SparroWatch includes a real-time graphing function as well as a data logger.  AFS’ technical support team can often suggest calibration improvements or detect a malfunctioning component after analyzing an emailed log file.


AFS’ USB Datalink communication tool enables programming, calibration and field servicing of AFS controllers.  This recent addition to the AFS product line uses its own microprocessor to manage communication between the controller and any standard USB port of a Windows-based PC.  Speed and reliability are markedly improved compared with older serial port communication tools.

An enhanced version, the Datalink Plus, can function without a PC in stand-alone, unattended data storage mode.  This device stores selected operating data to a built-in flash memory card for later download and analysis on a PC.  Able to store weeks of data at a time, this has proved a very useful troubleshooting tool for capturing events that can prove difficult to repeat, or for “replaying” key sequences such as emissions certification cycles.
