1. Introduction

Page 10 USN52 L Operating Manual

• RF display mode improves signal evaluation and bond inspec-

tion of dissimilar materials and assists crack tip detection and

sizing.

• Selectable rep rate minimizes phantom echoes caused by wrap

around noise.

• Four step damping control provides transducer matching for

broader range of applications.

• Four step frequency control provides selectable amplifier

bandpass for optimum signal to noise.

• Amplitude and time of flight analog output enables recording

via strip chart or digitizing device.

• Magnification window displays measurement value in large,

easy to read digits.

• 40 dB dynamic DAC/TCG enables correction for distance/

amplitude variations due to material loss and beam spread.

Meets or exceeds all current industry requirements for TCG.

• Angle beam trigonometric functions display sound path, pro-

jection, and depth measurements to flaw.

• On-board thickness data logger stores a total of 2500 readings

in up to 99 configurable files.

1.2 Features of the USN52 L

The USN52 L is a very lightweight, microprocessor controlled, ul-

trasonic flaw detector. It may be used on a wide variety of materi-

als for:

• locating and evaluating material discontinuities, and

• measuring wall thickness from one side of the part.

Its compact size and full range of features provide a combination

of versatility and portability never before available in an ultrasonic

flaw detector.

Because functions are selected from menus and controlled by sim-

ply pressing a key, the unit is easy to learn and operate. Important

control settings are saved when the instrument is turned off and

restored when the power is turned on again.

Other important features of the USN52 L:

• 5.98 pounds total weight with batteries

• High visibility, LCD display with backlight (480 x 320 pixels)

• Sealed case and membrane keypad are rugged and easy to

clean.

• 60 Hz A-scan update rate in all ranges at high PRF

• Operates with an external Power Supply/Charger or 6 “D” size

alkaline or NiCad batteries in a detachable housing.
