CHAPTER ONE INTRODUCTION The Dakota NDT model FX70 is both, an ultrasonic flaw detector, as well as an ultrasonic A/B Scan thickness scope, in a single unit. It’s a combination of both our CMX3-DL, as well as our new FX70 flaw detector series. Why is this advantageous? Thickness gauge are specifically setup to very accurately measure thickness, locate pits, flaws and blind surface corrosion.
1.2 Electrical Warning The FX70 contains a high voltage pulser. It’s recommended that the gauge be powered off prior to connecting or disconnecting your transducer, to avoid damaging the FX70.
CHAPTER TWO QUICK START GUIDE This section will cover a basic quick start guide to initially get up and running with the FX70 for demonstration purposes only. However, in order to use the gauge and features for actual applications, a thorough review of this manual is recommended. 2.1 Gauge Type Power up the FX70, by pressing the on/off key located in the bottom right corner of the keypad.

CHAPTER TEN DISTANCE, GAIN, SIZE (DGS) 10.1 Introduction to DGS (AVG) The DGS (Distance, Gain, Size) method was introduced in 1958 as a way to standardize the process of evaluating and sizing defects, also referred to by the German acronym AVG. This method uses a combined empirical and mathematical model to eliminate the need for a large range of reference standards, generally required when using the DAC or TCG methods.
FX70 Series Ultrasonic Flaw Detector Considerations: Should only be used with single element probes. The effective diameter must be estimated for standard transducers not certified for DGS. Center frequency clarity is required. Highly damped transducers can sometimes produce a broadband frequency range, and should not be used. 10.2 DGS Diagram In order to get familiar with the DGS diagram, let’s take a look at some of the general concepts.
Page 82
Dakota NDT Where: N = Near Field Length = Effective Diameter = Wave Length (velocity/frequency) In order to approximate the effective diameter, the shape of the crystal must be taken into account. Transducers are either round or square/rectangular in shape, and can be approximated as follows: Round Crystal (D ...

Dakota NDT Reference Gain: Activated to set the reference gain using a given reflector from a calibration standard. Trigger Curve: Enables the user to set the detection curve to either DGS or GATE. This will be the curve used to trigger the alarms and display the effective reflector size (ERS) during the inspection process.
FX70 Series Ultrasonic Flaw Detector DVK (Curvature Correction): If a V1/K1 or V2/K2 (A2/A4, IIW/Kidney) calibration standard is used as a reference reflector, the curved surface offers additional focus normally resulting in greater signal output. DVK is a correction to the gain, in order to simulate the amplitude generated from a flat back wall.
