12 MEASUREMENT - OPTIONS
12.1 AUTO FIND
When using a scan type display, the DELAY and RANGE (or B-START and B-DEPTH) must be set
correctly for the waveform to be shown on the display. If these parameters are set up incorrectly
nothing will be seen. The AUTO FIND function solves this problem by automatically adjusting these
parameters so that the relevant part of the waveform is shown on the screen.
To use the AUTO FIND function place the transducer on the material to obtain a reading, select
MENU/UTIL/AUTO FIND.
12.2 HIGH SPEED SCAN
Although your gauge excels at making single point measurements, it is sometimes desirable to
examine a larger region, searching for the thinnest point. The gauge includes a feature, called Scan
Mode, which allows it to do just that.
This mode increases the overall repetition rate to a maximum of 140 Hz with a high speed screen
refresh rate of up to 120 times a second.
This feature enables the user to make scanned passes over an arbitrary length of the test material
while still maintaining a reasonable representation of thickness over the scanned area or region.
This feature can be used in conjunction with High and Low alarm limits features to keep track of
both values dynamically.
To enable/disable the high speed Scan Mode:
1. Select MENU/UTIL/SCAN MODE.
2. Use the LEFT and RIGHT arrows to toggle the SCAN MODE on/off.
3. Press MEAS to return to the measurement screen, ready to begin taking readings.
12.3 ALARM MODE
Your gauge includes an Alarm Mode. Set the limits, and if a measurement falls outside of these
limits your gauge will signal an alarm (a red light on the front panel of the instrument and/or an
audible beep).
This feature may be used for a variety of applications to verify the material is within the manufacturer
specifications.
There are two limit values, ALARM LOW and ALARM HIGH. You can choose to activate both or
just one of these values depending on your requirements.
To enable/disable Alarm Mode:
1. Select MENU/UTIL/ALARM.
2. Use the LEFT and RIGHT arrows to toggle the ALARM on/off/audible.
3. Press MEAS to return to the measurement screen, ready to begin taking readings.
To set the Alarm limits:
1. Select MENU/UTIL/ALARM LOW or ALARM HIGH.
2. Press ENTER to display the Digits Edit Box.
