Variable over the whole sweep range in steps of 0.1 mm, alarm indication with
flashing LEDs, threshold adjustment from 10 to 90% screen height, separate second
monitor threshold for the multiecho measurement mode with controlled blocking and
first echo start functions
Zero to first echo, multiple echo in gate with adjustable second threshold, time of
flight to peak or flank in gate, amplitude evaluation as a % of screen height or as a
dB difference to the reference echo up to 127%. dB reference value with reference
gain data as well as gain changes as + or - values (indicated on display)
Automatic calculation and display of flaw position in angle beaming:
• sound path
• projection distance
• reduced projection distance
• depth
• number of reflections (graphically) on flat and uniformly curved test objects up to a
minimum diameter of 52 mm
Up to 140 instrument setups, storage of all instrument parameters and A-scan,
presentation and printout of stored A-scans
Sequential storage of 2500 thickness readings with clear, review and direct report
features, configurable up to 99 files, measured values for the corresponding files are
determined by the file configuration
Recording of up to 9 reference echoes, dynamic range 40 dB, maximum slope
6 dB/µs, representation as Curve (DAC) and Time-Corrected Gain (TCG)
