CHAPTER ONE: INTRODUCTION

The CHECK-LINE model TI-MVX is a visual A / B scan ultrasonic thickness

gauge. Based on the same operating principles as SONAR, the TI-MVX is

capable of measuring the thickness of various materials with accuracy as high

as ± 0.001 inches, or ± 0.01 millimeters. The principle advantage of ultrasonic

measurement over traditional methods is that ultrasonic measurements can be

performed with access to only one side of the material being measured.

CHECK-LINE maintains a customer support resource in order to assist users

with questions or difficulties not covered in this manual. Customer support may

1.1 Disclaimer

Inherent in ultrasonic thickness measurement is the possibility that the instru-

ment will use the second rather than the first echo from the back surface of the

material being measured. This may result in a thickness reading that is TWICE

what it should be. Responsibility for proper use of the instrument and recognition

of this phenomenon rest solely with the user of the instrument.
