• 2-stage adjustment of pulse repetition rate in order to
avoid phantom echoes,
• indication of amplitude and sound path for flaw
testing and thickness measurement,
• DAC for convenient display evaluation according to
the reference block method (e.g. ASME code, etc.),
• analog outputs for external control purposes: propor-
tional voltage for amplitude and sound path of the
echo in the monitor gate,
• A-scan storage, peak freeze and zoom function,
• preview of all stored A-Scans,
• locking function to avoid unintentional alteration of
set values,
• magnified display of measured values for easy
reading even from longer distances,
• rapid switching between programmable sound
velocities, e.g. for longitudinal and transverse waves
in steel.
• 60 Hz A-scan refresh rate,
• mains power or battery operation (max. 5 hours of
operation),
• on-board Data Logger for storage of up to 2,500
thickness readings in a maximum of 99 freely
configurable files,
• RS232 interface for data transfer, A-scan displays
and reports, or for remote control of the USN 52 R,
• storage of 140 (USN 52R) / 100 (USN 52L) control
data sets enabling quick calibration and reproducibil-
ity of the test,
• alphanumeric entry of data set names and display of
a directory of all data sets,
• frequency ranges from 0.25 - 11 MHz wide band
• echo representation: RF signal, full-wave, positive
and negative half-wave,
• optimized probe matching by means of 4 adjustable
damping values between 50 and 1000 ohms,
• automatic calibration of the sound velocity and probe
delay according to data from 2 calibration echoes
(with plausibility check),
