ALTANA Gardner-Scrub Manual - Manual (Page 6)

The Gardner-scrub incorporates a precise speed control to maintain a constant speed for the
test. The instrument is preset at 37 strokes per minute to coincide with most standardized
tests, but may be adjusted within the range of 6 to 60 strokes per minute. Unlike some other
instruments on the market, the Gardner-scrub maintains a linear speed over its travel length.
The result is a more consistent and repeatable test.
A front mounted, color touch screen is provided for user interaction. All adjustments are
available in the setup screen to provide a flexible interaction with the user.
The instrument is setup at the factory for a center-to-center stroke length of 10 inches. Stroke
lengths of 9 or 11 inches may be achieved by means of a mechanical adjustment. This
adjustment must be performed by the factory or an authorized service center.
