ECHO Series Ultrasonic Thickness Gages
99
Gages equipped with the Live Waveform option will have a screen similar to the one
shown below, which is a 1" test block with echoes displayed and un-calibrated at
0.9953". The calibration procedure for ECHO 7 and 8 is the same as described in this
manual.
If you have a gage with thickness only, the screen will appear as shown below:
There are several adjustable parameters for ECHO 7 and ECHO 8 when equipped with a
live waveform. The purpose of the live waveform is to view the detected echoes and
verify that they are correct as they relate to the thickness being displayed. You can adjust
the following parameters using the left or right arrow keys:
Initial gain I.DB.: How much the initial gain is set to
Final gain F.DB.: Final gain used to boost echoes
Slope SLOP: Slope between Initial gain and Final gain
Rectification RECT: Full wave, half +, half -, RF
