Initial Setup
55
The available rectification modes are:
FULL
Shows the negative portion of the echo folded around the baseline so that both
positive and negative waveform lobes are displayed. Gives the best overall
representation of position and magnitude for most thickness measurement
applications. FULL is the default mode for dual element transducers.
HALF– (NEG indicator)
Shows negative waveform lobes as positive and does not show the positive lobes.
HALF+ (POS indicator)
Shows positive waveform lobes and does not show the negative waveform lobes.
RF
Shows negative and positive lobes on either side of the baseline. RF is the default
mode for single element transducers.
4.4.4 Waveform Trace
The 38DL PLUS can display the waveform trace as a line (OUTLINE) or as a FILLED
area (see Figure 4-6 on page 56). From the measurement screen, press [DISPLAY] to
access the WAVEFORM TRACE parameter.
A filled waveform trace is only possible when the waveform rectification is set to
FULL, HALF+, or HALF–.
