Epson USN 52R- User Manual

USN Series

Handle tough applications in any environment...
because tests are required everywhere!

Inspection oriented and easy
to use

• 40 dB dynamic DAC/TCG

enables cor rection for
distance/amplitude var-
iations due to material loss
and beam spread Cur ve
displayed on A-Scan.
(USN 52L/R)

• RF display mode improves

signal evaluation and bond
inspection of dissimilar ma-
terials and assists crack tip
detection and sizing.
(USN 52L/R)

• Selectable rep rate

minimizes wraparound.

• Selectable damping control

provides transducer
matching for broader range
of applications.

• Angle beam trigonometric

functions display sound
path, projection, and depth
measurements to flaw.

• Magnification window

displays measurement
value in lar ge,easy to r ead
digits.

• Gate monitors amplitude

and soundpath distance for
both flaw and thickness
applications.

• Multi-echo or inter face-to-

first thickness measur e-
ment mode, with selectable
flank or peak detection.

• A-Scan freeze, freeze peak,

and zoom functions.

• Lock key prevents ac-

cidental change of settings.

Documentation and recording

• On-board thickness data

logger stores a total of
2,500 readings in up to 99
configurable files.

• RS-232 bidirectional

inter face for transfer ring
data, A-scan displays, and
repor ts to a printer, com-
puter, and for remote control.

• Stores instr ument control

datasets with A-Scans in
memor y for quick and
repeatable calibration.

• Amplitude and time of flight

analog output enables
recording via strip char t or
digitizing device.

(USN 52L/R)

• Direct printing of inspection

repor ts.

Lightweight, advanced and
reliable

• 6 pounds (2.7 kg) total

weight with batteries.

• Sealed case and membrane

keypad are splashproof,
r ugged and easy to clean

• Operates on AC or 6 “D” size

alkaline or NiCad batteries in
a detachable housing
