Chapter 2 25

The QS5 E and QS5 DLE gauges can measure thru-coatingings such as
paint  or  epoxy  so  you  no  longer  need  to  scrape  and  remove  the
coating in a test piece. The unit now “skips” the coating and measures
only the actual test piece thickness.

To  enable  thru-coating  or  thru-paint  mode  (Echo-2)  touch  the

(Echo) key from the measuring screen and the unit will display the
mode you are in. (Echo-1 normal, or Echo-2 coating (thru-paint).

Switch between Echo modes touching

and wait until the window

indicating the mode you are in disappears. This means that the unit is
now set for the Echo mode you selected.

Figure 2.12: Change of Echo windows (normal or coating)

Multi-echo units use separate ultrasonic configurations for each echo
mode.  This  means  that  when  switching  between  Echo-1  and  Echo-2
modes  the  gain,  trigger  and  voltage  of  the  pulse  emission  are
maintained  for  each  mode.  In  the  example  below  the  gain  level  for
Echo-1 is 75 and for Echo-2 it is 63. These gain levels will not change
as you switch modes.
