10.2 High Speed Scan
The High Speed Scan feature of the DFX-7 increases the overall repetition rate to a
maximum of 140Hz with a high speed screen refresh rate of 25 times a second. This
feature enables a user to make scanned passes over an arbitrary length of the test
material, while still maintaining a reasonable representation of thickness over the
scanned area or region. This feature can be used in conjunction with High and Low
alarm limits features to dynamically keep track of both values. The feature is typically
used to provide a better representation of the area scanned, by taking more readings
at a faster rate repetition rate.
The procedure to use the SCAN MODE feature is outlined below:
Using the Scan Mode
1) Press the MENU key once to activate the menu items tab. Press the MENU
