Krautkramer USN 52R/USN 52L Issue 05, 02/00 8-21
Analog voltage for the echo amplitude (echo
in the monitor gate)
a) Rectified echoes
0 volt: no echo in the gate;
echo amplitude = 0% screen HT
2.5 volts: echo amplitude = 128% screen HT
b) RF mode
-1.25 volts: echo amplitude = -64% screen HT
+1.25 volts: echo amplitude = +64% screen HT

Analog voltage for the sound path of an echo
a) MEASURE = 0 TO 1st
0 volt: sound path = a-START;
echo is exactly at gate start
1.25 volts: sound path = a-START +0.5 a-WIDTH;
echo is exactly at gate center
2.5 volts: sound path = a-START + a-WIDTH;
echo is exactly at gate end
2.5 volts: no echo in the gate
b) MEASURE = MULTECHO
The output voltage corresponds to the ratio of the mea-
sured wall thickness to the gate width. If there is no
echo in the gate, the output voltage is 2.5 volts.
