Figure 7-5 Example Of A B-Scan Alarm Mode - Olympus 45MG User Manual

There are three different alarm modes (STANDARD, B-SCAN, and REDUCTION
RT):
STANDARD
The standard alarm warns you when the actual measured thickness is below a
low reference value, or above a high reference value. The reference values are
thickness set points using the current instrument units and resolution.
NOTE
The B-SCAN and REDUCTION RT alarms are only available when the B-scan or
reduction rate (DIFF mode) are activated. These functions must be turned on first
before the B-SCAN and REDUCTION RT alarms can be activated.
B-SCAN
The B-scan alarm mode is similar to the standard alarm mode, except that in the
B-scan alarm mode, lines are shown in the B-scan grid when the reference values
fall within the B-scan thickness range (see Figure 7-5 on page 133). In addition, the
alarms are operational while you review B-scan thicknesses in the B-scan freeze
review mode.
