CHAPTER ONE INTRODUCTION
The Dakota Ultrasonics model MVX is a visual A / B scan ultrasonic thickness gauge. Based on the same operating principles as SONAR, the 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. Dakota Ultrasonics maintains a customer support resource in order to assist users with questions or difficulties not covered in this manual. Customer support may be reached atany of the following:

• Dakota Ultrasonics Corporation, 1500 Green Hills Road, #107 Scotts Valley, CA 95066 USA • Telephone: (831) 431-9722 • Facsimile: (831) 431-9723 • www.dakotaultrasonics.com 1.1 Disclaimer
Inherent in ultrasonic thickness measurement is the possibility that the instrument 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.

CHAPTER TWO QUICK STARTUP GUIDE
Turn the MVX on and off using the switch located on the bottom right corner of the keypad. When MVX is initially turned on, a flash logo and blinking lightswill be displayed prior to entering into the main measurement screen. Note: This section is primarily written as a basic startup guide only.

2.1 Selecting The Transducer Type
The first step in using the MVX is to select the transducer type according to frequency and diameter. By selecting the transducer type from a predefined list, the MVX can recall specific properties about the transducer.Note: Once the transducer has been selected, the MVX will store and recall this transducer type every time the MVX is powered on/off. The type will only change if the user physically selects another transducer type from the list, or selects a previously saved setup. Therefore, if you have previously gone through this section and selected the transducer you are using, proceed to the next section. Usethe following steps to select your transducer type:

Selecting the Transducer Type

1) Press the MENU key once to activate the menu items tab. Press the MENU key multiple times to tab right and the ESC key multiple times to tab left until the PROBE menu is highlighted and displaying the submenu items.
