Settings for individual tests can be changed at the time of testing, but users may also change the test defaults in the Tracker™ software for each instrument.  

By navigating to the "Test Selection" screen for a given instrument, the user may choose from among the "Test Settings" options at the bottom of the window. Any selections made on this screen will be reflected in all future tests for that instrument.

(Note: To promote consistency in testing, defaults will be overridden if a patient's previous exam was performed with different settings. The Tracker Version 5 software will always return to the settings last used for the patient. These can be manually changed by the user at the time of testing.)
