MATL 2PT: Performs a two-point calibration. This option allows the user to
automatically calculate the velocity by entering a second known sample thickness.
Refer to page 56 for further info.
VELOCITY: Function to calibrate the DFX-7 by setting the velocity to a known
material velocity. Refer to page 52 for further info.
COATING 1PT: Performs a single point coating calibration. This option allows the
user to automatically calculate the velocity by measuring a known coating sample
thickness. Refer to page 104 for further info.
COATING 2PT: Performs a two-point coating calibration. This option allows the
user to automatically calculate the velocity by entering a second known coating
sample thickness. Refer to page 104 for further info.
COATING VEL: Function to calibrate the DFX-7 to a specific coating material type
by entering a coating velocity. Refer to page 16 or page 98 for further info.
3.4 DISP (display) – Menu
VIEW: Selectable BSCAN (cross section), and DIGITS (large digits) views. Refer to
page 61 for further info.
DELAY (B-START): Provides the user the ability to change the start position of the
B-SCAN view. Refer to page 69 for further info.
RANGE (B-DEPTH): Provides the user the ability to change the overall depth of the
viewable measurement area. It functions a lot like a zoom on a camera. Refer to
page 71 for further info.
B-SCAN SPEED:
Controls the speed of the time based B-Scan with an arbitrary
scale of 0-10, with 10 being the fastest scrolling speed. Default speed set at 6.
Refer to page 73 for further info.
UNITS: Toggle between English or Metric units. The readout will change from
inches to millimeters.
BRIGHTNESS: AMOLED high speed color display. An arbitrary scale of 1-20 has
been implemented, with the brightest setting at 20. Refer to page 115 for further info.
VIEW:
Provides the user with 12 different color schemes to select from. There are
two schemes for each main color option. Refer to page 117 for further info.
DIM:
Allows the user to conserve battery life by diming the display after idle for a
specific amount of time – OFF, 30, 60, 90, 120 seconds. Once dimmed, a single
press of any key will restore the screen brightness. Refer to page 118 for further info.
