that only the material thickness is measured. This feature saves you a great deal of time scraping
and removing the coating from tanks and pipes during the inspection process.
The primary purpose of ThruPaint™ measurement is to determine overall material thickness;
ThruPaint™ mode cannot be used for flaw or pit detection. Therefore, inspectors typically use this
echo-echo ThruPaint™ mode in conjunction with a standard pulse-echo flaw detection mode. The
combination of using both modes is ideal for the advanced inspectors needs.
11.2 Setting Up ThruPaint™ Mode
When you select the appropriate transducer type from the list of probes stored in the gauge, a basic
echo-echo ThruPaint™ configuration is recalled from memory. Each of the transducers in the list
contain pre-configured echo-echo settings. However, fine adjustments may be necessary for
specific applications. Once the transducer type has been selected and the appropriate calibration
procedure completed, you can toggle between pulse-echo (flaws and pits), and echo-echo
(ThruPaint™) modes by pressing
.
Note: When you have configured your gauge settings, save these changes to a setup location prior
to switching off the gauge. Failure to do so will result in losing your changes.
12 MEASUREMENT - OPTIONS
12.1 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 from 4 readings a second to 32 readings a second.
This feature is typically used for scanning cylinder walls to speed up the overall inspection process.
Note: It is recommended that at least 2-3 scans are made per clock position, and all clock positions
are scanned in each cylinder. By taking the time to do the multiple scans in all the clock positions
of the cylinder, you will have some level of confidence that measurements obtained are
representative of the individual cylinders in the block. When you are scanning a cylinder, the display
will continue to be updated during the scan process, and when the transducer is removed, the
gauge will display the minimum reading found.
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. Press
, scroll to the UTIL menu and then highlight the SCAN MODE function.
2. Use the
and
arrows to toggle the SCAN MODE on/off.
3. Press
to return to the measurement screen, ready to begin taking readings.
Alternatively, adjust the SCAN function in the hot menu.
