Automatic A-scan freeze (Freeze)

In the function group CONFIG2, the USM 36 offers with
its function FREEZE MODE various options for auto-
matic freezing of the A-scan.
The following settings are possible:
● STANDARD
By assigning the function FREEZE to one of the func-
tion keys, you can manually freeze the A-scan
(see Chapter 5.3 Assignment of function keys,
page 5-7).
5-68
● A-FREEZE
The A-scan is frozen automatically when the signal
touches the gate A. This setting is suitable e.g. for
measurements on hot test objects, for measurements
in difficult coupling conditions, or for spot weld test-
ing.
● B-FREEZE *
The A-scan is frozen automatically when the signal
touches the gate B. This setting is suitable e.g. for
measurements on hot test objects, for measurements
in difficult coupling conditions, or for spot weld test-
ing.
● AB-FREEZE *
The A-scan is frozen automatically when the signal
touches either one of the gates A or B.
● COMPARE
The manually frozen A-scan is displayed for compari-
son purposes in the background while the currently ac-
tive A-scan is at the same time visible in the foreground.
When leaving the function FREEZE, the last A-scan is
recorded and displayed for comparison purposes.
* If the function B START MODE is set to A for the gate
B, the function FREEZE will not be effective until the
interface echo has also reached the gate A before-
hand.
