highlighting differences from the
reference. |
|
DAC |
DAC curves may be entered and digitally
drawn on the display. Reference,
-6dB, -12dB,-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 comply with ASME and European
Standards. |
|
TCG |
Time Corrected Gain curves may be
entered and digitally drawn on the
display. The dynamic range of the
