GE Krautkramer USM 35X - Setting the Gates (Function Groups Agat and Bgat); Tasks of the Gates

5-14 Issue 01, 04/2005 Krautkramer USM 35X
Operation Setting the gates (function groups aGAT and bGAT)
5.6 Setting the gates
(function groups aGAT
and bGAT)
All functions for setting the (dual) gate are arranged in
the function group aGAT and bGAT.
– If required, go to the first operating level.
– Select the function group aGAT or bGAT.
H Note:
If you have an instrument equipped with the Data Logger
option at your disposal, you’ll be additionally able to use
the C gate including all corresponding functions.
Tasks of the gates
• It monitors the range 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 via the
LED A.
• The gates A and B are independant of one another.
Gate A can also have the function of an echo-start
gate.
• The gate chooses the echo for the digital time-of-
flight or amplitude measurement. The measured
value is indicated in the measurement line.
H Note:
Error alarms can be triggered unter certain circum-
stances. These are caused by intermediate conditions
in instrument operation occuring when the instrument is
