The 38DL PLUS uses a transflective color display that reflects ambient light and
becomes brighter in direct light. With brighter ambient conditions, you can set the
display brightness to a lower percentage.
Reducing the display brightness percentage increases the battery life. Battery life
specifications are based on backlight brightness set to 50 %.
4.4.3 Waveform Rectification
The rectification mode is the way in which the ultrasonic echoes are represented on
the waveform display (see Figure 4-5 on page 54). The rectification mode does not
affect the thickness measurement in any way. The rectification indicator (FULL, POS,
NEG, or RF) appears on the left edge of the waveform display. From the measurement
screen, press [DISPLAY] to access the WAVEFORM RECTIFICATION parameter.
