Chapter 1 Overview

When ultrasonic waves transmit in test materials, acoustics properties will be

effected due to flaws existing in the material, thus these properties can be used to

demonstrate flaws within the material. According to this theory, by use of

ultrasonic waves can detect flaws like crack, cavity, inclusion when test various

media such as metal, non-metallic materials and composite materials.

Digital ultrasonic flaw detector 3&(86& is a portable industrial non-destructive

flaw detector, which can quickly and easily, without damage, accurate to a variety

of work piece defects (cracks, inclusions, cavity, etc) of the detection, location,

assessment and diagnosis. Both can be used in laboratories and project site.

PCE-USC 20 is widely operated in the field of flaw detection and quality control,

such as manufacturing industry, metallurgy of iron steel , metal processing

industry, chemical lines , as well as operated in in-service safe inspection and life

appraisal, such as aerospace, railway transportation, boiler and pressure vessel

safety check in service and life assessment.

3&(86& is a high-tech instrument which launched by PCE Instruments.

Full consideration of ergonomic

made for instrument’s appearance, its structure is strong and light, easy and

comfort to take, as well as shockproof. Scientific and rational setting of keystroke

and menu, common features can be simply operated for more efficiency and less

labor intensity. Instrument complies with European standard EN12668-1, has

more advantages like high performance, stability, functional and practical, reliable

quality, anti-interference ability and so on, also in full compliance with most

industry standards, high praise for it both from domestic and abroad, after the

software version upgrade to Ver1.10 it become more convenient for operation.

3&(86& is equipped with imported lithium batteries, no memory effect, with

high capacity, batteries service time can up to more than 8 hours, it is priority

choice for testing operations especially for field work.

2.2 Features and Functions

2.2.1 Features

(1) Leading technical target, abundant applied assistant function

(2) Intelligible setting of keys and menu, easy to operate

(3) 400 MHz real-time hardware sampling, high-fidelity echo pulse

(4) Broadband and amplifying circuit with low noise, selectable damping, excellent

matching with low or high frequency probe

(5) Excellent EMI design，good EMC performance

(6) 5.7〞high resolution color LCD display

2.2.2 Main Functions

(1) DAC Making, Storing and Recalling Function

(a) Making easily

When sampling dots one by one, it will automatically draw four lines such

as “Assess Line”, “RATINE Line”, “GENERATRIX Line” and “Void Line”.

(b) Compiling conveniently

It can automatically modify each sampling dot and adjust the curve offset(to

fit all kinds of standards).

(2) AVG Making, Storing and Recalling Function

(a) Making easily

It can draw curve by sampling one dot in “>3N” area automatically, or by

sampling dots one by one in “<3N” area, which ensures the practicality.

(b) Applying conveniently

It can automatically adjust the curve equivalent and calculate the flaw

equivalent sizeΦautomatically.

(3) RF Displaying Function

It can display the real original waveform, which is convenient for the user to

analyze the details of the echo and help to analyze the flaw qualitatively.

(4) Curve Surface Amending Function

It can amend the test result of the arc surface automatically.

(5) Peak Holding Function

Assist to record the maximum echo.

(6) Envelope Function

Record the changing profile of the echo.

(7) Automatically Testing Echo Spectrum Function

It is used to test the center frequency and its spectral characteristics of the

probe echo.

(8) Auto Gain Adjusting Function

The adjustable Auto Gain can be used to set echo amplitude conveniently.

(9) Weld Graph Displaying Function

The graph displaying is intuitional, which makes the flaw position legible. The

graphs can be stored in the flaw detection report, which is convenient to be

replayed and printed.

(10) Intelligent Calibrating Procedures

It is used to calibrate the material sound velocity rapidly, measure the probe

delay automatically, calibrate the refraction angleβautomatically, and

calibrate the probe easily.

(11) Setting Quick Channels Function

It has 30 quick channels which can store 30 groups of detect parameters in

all, which makes the storing and recalling easily.

(12) Automatically Generating Reports Function

It generates detection reports based on detecting parameters and data

automatically. The detection reports contain detailed detecting parameters,

waveform graphs and detailed echo data, which can be directly printed by the

connected printer or stored in the computer.

(13) Continuously Storing and Replaying Function

It can record the dynamic waveform while detecting, which makes the

recorded data more detailed. The menu settings are analogous to the video

function, which is easy to be understood and operated. The stored

documents can be re-stored to the U disk or other storage devices directly at

any time.

(14) Waveform Display Area Zoom Function

The waveform display area can be zoomed in to full screen, which can

efficiently prevent misuse in field testing.

(15) Gate Area Zoom-in Function

The Gate area can be zoomed in to the whole display area, which is

convenient to observe the waveform details.

:gain-step adjusting key. Press it for switching gain-step value cyclically by

one of the step values in the array of 0.0/0.1/0.5/2.0/6.0dB. (Represented by

[↔] below.)

:gain increasing key. Press it each time for increasing gain value, by which the

increment is the current step value. (Represented by [dB+] below.)

:gain decreasing key. Press it each time for decreasing gain value, by which

the decrement is the current step value. (Represented by [dB-] below.)

Note: when the step value is "0.0dB", it means that the gain is unadjustable,

which is convenient for the user to prevent misoperation in detecting.
