MG2 Series

Page 4-33

Echo Blank Set Too Small; Gage Reading Trailing Edge of First 
Backwall Echo

E1 (Echo1) Blank Set Properly; Gage Making Proper Detection 
Between Successive Backwall Echoes

4.13.4 Range

Range Adjust allows the user to adjust the range of the waveform so 
that the measured echoes appear on screen. Range Adjust is not 
available if the Waveform Zoom Option is turned on.
