Description
PRB
(PROBE)
ZERO PROBE
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.
ZERO COATING
In order to account for very slight electronic differences in
transducers of the same type, frequency, and diameter,
your gauge includes this "zero coating" feature. This fea-
ture enables your gauge to obtain very accurate readings
on coatings, eliminating potential errors incurred from slight
differences in the transducer manufacturing processes.
TYPE
Use this function to select the type of transducer being
used from a chart of transducer types. This provides
increased linearity between transducers.
FLAW
Activates the flaw detection mode and view. This feature is
for use with single element angle beam transducers and
used as a general prove-up flaw inspection mode.
CAL
(CALIBRA-
TION)
MAT
Select the material velocity from a chart of basic material
types when a known sample thickness, or material velocity
cannot be obtained.
MATL 1PT
Performs a single point calibration. This function allows you
to automatically calculate the velocity by entering a known
sample thickness.
MATL 2PT
Performs a two-point calibration. This function allows you to
automatically calculate the velocity by entering a second
known sample thickness.
VELOCITY
This function calibrates your gauge by setting the velocity
to a known material velocity.
COATING 1PT
Performs a single point coating calibration. This function
allows you to automatically calculate the velocity by meas-
uring a known coating sample thickness.
COATING 2PT
Performs a two-point coating calibration. This function
allows you to automatically calculate the velocity by enter-
ing a second known coating sample thickness.
COATING VEL
This function calibrates your gauge to a specific coating
material type by entering a coating velocity.
