Tasks of the gates

● The gates monitor the area of the test object where
you expect to detect a flaw. If an echo exceeds or falls
below the gate, an alarm signal is output (see Section
Alarms, page 4-6).
● The gates A and B are independent of each other.
Gate A can also assume the function of an echo start
gate for gate B.
● The gate chooses the echo for the digital time-of-
flight and amplitude measurement. The measured
value is displayed in the measurement line (see Sec-
tion Measurement line, page 4-5).
Display of the gates
Gates are displaced in different colors for ease of iden-
tification.
