A-Scan Memory: Maximum of 100 waveforms stored with complete panel
settings. Waveforms may be recalled on display, printed
or transferred via RS232 serial interface.
Panel Memory: 20 stores for retaining calibrations
Thickness
Logging: Storage for 2000 thickness readings configured into
Block/ Location/Number. Calibration settings stored with
each Block. Maximum number of Blocks is 14. Unlimited
Location/Number values, maximum combination of 2000
readings. Readings may be reviewed, edited and printed
as required.
DAC: DAC curves may be entered and digitally drawn on the
display. Reference, -6dB, -12 dB, -14dB curves may be
selected. DAC curve selected acts as gate for alarm
outputs and height measurement in DAC +dB. DAC
parameters stored with Panel Memory. Curves available
for ASME and JIS Codes.
AWS: Built in Software for evaluation of defect indications in
accordance with AWS standards
TCG: Time Corrected Gain, also known as Swept Gain. 40dB
dynamic range greater than 30dB per Microsecond and
up to 10 points may be used, setting all signals initially to
80% Full Screen Height.
Auto-Cal: Provides Automatic calibration from two echoes.
Video: Composite video selectable between NTSC and PAL.
Clock: Sets time and date.
Reference
Waveform: This menu displays a waveform from one of the A-Log
stores as a reference or fingerprint display in a colour
different from the active display highlighting differences
from the reference.
Notes: Alphanumeric labelling for panel and A-Log allows the
user to enter Notes for storage with A-scans.
X-Offset: Allows the surface distance to be calculated from the
front of the probe with X-offset being the distance from
the index point to the front of the probe.
Display Freeze: Freezes current A-scan image.
Peak Memory: For echodynamic pattern determination.
Keylock: Prevents accidental alteration of parameters
Help Key: For instant operator guidance on using the SITESCAN
240
Waveform
Smoothing: Gives a smooth signal envelope similar to the video
filtering in analogue equipment.
