9.3.2 Using the B-Scan Alarm Mode
You can specify B-scan low and high alarm reference values, and turn the visual and
audible alarm functions ON and OFF. The B-scan alarm mode is similar to the
standard alarm mode (see “Using Alarms” on page 131), except that the alarm lines
are shown in the B-scan grid if the alarm reference values fall within the B-scan
thickness range. The alarms are also operational as you review B-scan thicknesses in
review mode within a frozen B-scan.
To use the B-scan alarm mode
1. Activate and configure the B-scan (see “Using the B-Scan” on page 156).
2. While in the measurement screen, press [SETUP], and then select ALARM.
3. In the ALARM screen (see Figure 7-7 on page 135):
a) Set ALARM ENABLE to ON.
b) Set ALARM MODE to B-SCAN.
c) Enter the desired LOW ALARM and HIGH ALARM values.
4. Press [MEAS] to return to the measurement screen.
5. The horizontal red alarm lines appear on the B-scan (see Figure 7-5 on page 133).
