Introduction
MX-3
is a precision Ultrasonic Micrometer. Based on the same operating principles as
SONAR the
MX-3
is capable of measuring the thickness of various materials with accuracy
as high as
±
0.01 mm.
The principle advantage of ultrasonic measurement over traditional methods is that ultra-
sonic measurements can be performed with access to only one side of the
material being measured.
This manual is presented in three sections.
•
The first section covers operation of the
MX-3
and explains the keypad controls and
display.
•
The second section provides guidelines in selecting a transducer for a specific ap
plication.
•
The last section provides application notes and a table of sound velocity values for
various materials.
Operation
MX-3
interacts with the operator through the membrane keypad and the LCD display. The
functions of the various keys on the keypad are detailed below, followed by an explanation
of the display and its various symbols.

This key is used to turn the
MX-3
on and off. When the tool is turned ON, it will
first perform a brief display test by illuminating all of the segments in the display. After one
second, the tool will display the internal software version number. After displaying the
version number, the display will show „0.00“, indicating the tool is ready for use.
he tool has a special memory that retains all of its settings even when the power is off. The
tool also features an auto-powerdown mode designed to conserve battery life. If the tool is
idle for 5 minutes, it will turn itself off.
The
PRB-0
key is used to „zero“ the
MX-3
in much the same way that a mechani-
cal micrometer is zeroed. If the tool is not zeroed correctly, all of the measurements that
the tool makes may be in error by some fixed value (see page 9).
