PVX-B
Precision Visual Thickness Gauge
13
Measure Mode:
Used to select the measurement mode for different application
requirements. The modes are P-E (pulse-echo), P-E GT(pulse-echo w/gate), and E-
E(echo-echo).
Note:
I-E or Interface echo mode is also a multiple echo mode that
uses two gates like E-E mode(echo-echo). Refer to page 21 for further info.
3.3 CAL – Menu
Units:
Toggle between English or Metric units and low and hi resolutions. The
readout will change from inches to millimeters (IN, IN HR, MM, MM HR). The high
resolution options are indicated with HR following the units, and offer an additional
decimal place of overall resolution (i.e. IN = .001” and IN HR = .0001”).
Velocity:
Function to calibrate the
PVX-B
by setting the velocity to a known material
velocity. Refer to page 31 for further info.
One Point:
Performs a single point calibration. This option allows the user to
automatically calculate the velocity by entering a known sample thickness. Refer to
page 33 for further info.
Two Point:
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 34 for further info.
Material:
Select the material velocity from a chart of basic material types, when a
known sample thickness or material velocity cannot be obtained. Refer to page 37 for
further info.
3.4 DISP (display) – Menu
View:
Selectable BSCAN (cross section), and DIGITS (large digits) views. Refer to
page 39 for further info.
Backlight:
Selectable OFF, ON, AUTO, or INVERT backlight option. The INVERT
option is actually a screen inversion that toggles background and foreground colors.
Contrast:
Adjustable display contrast for variable light conditions.
B-ST:
Provides the user the ability to change the start position of the B-SCAN view.
