PROBE
ZERO TRANS-
DUCER
Zeros your gauge in much the same way that a mechanical
micrometer is zeroed. If your gauge is not zeroed correctly,
all of the measurements made may be in error by some
fixed value. You can choose between automatic zero or
manual zero.
PULSE
Your gauge has adjustable pulse width for both high pene-
tration and resolution applications. The pulse width refers
to the duration of time the pulser is on. The options are
SPIKE, THIN, and WIDE.
CAL
(CALIBRA-
TION)
UNITS
Toggle between Metric (millimetres) or English (inches)
units.
VELOCITY
This function calibrates your gauge to a specific material
type by entering a material velocity.
ONE POINT
Performs a single point calibration. This function allows
you to automatically calculate the velocity by entering a
known sample thickness.
TWO POINT
Performs a two-point calibration. This function allows you
to automatically calculate the velocity by entering a second
known sample thickness.
MATERIAL
Select the material velocity from a chart of basic material
types when a known sample thickness, or material velocity
cannot be obtained.
DISP
(DISPLAY)
VIEW
Choose between RF wave, RECT (rectified) wave, BSCAN
(cross section), and DIGITS (large digits) views.
BACKLIGHT
Choose between OFF, ON, AUTO, or INVERT backlight.
CONTRAST
Adjust the display contrast for variable light conditions.
DELAY
Adjust where the left side of the display window starts
according to thickness, in inches or millimeters.
WIDTH
Set the overall depth of the viewable measurement area. It
functions a lot like a zoom on a camera.
