Use of this function saves you a great deal of time in the measurement process by letting the gauge locate
the detection point and bring the waveform signal into view automatically. If necessary, you can then make
small adjustments to the range once the signal is displayed on the screen.
In order to use AUTO SET, you must first enter into the gauge the approximate length of the bolt (ALEN /
APPROX. LEN.). The approximate length tells the gauge where to start looking for the echo during the
AUTO SET; the gauge se/- 5% from the value entered.
15.1.1 Setting the Approximate Length
The quickest way to adjust ALEN is directly from the hot menu. Alternatively, adjust the value using the
menus:
1.
Select MENU/AUTO/APPROX. LEN and press ENTER
2.
Adjust to the desired value
3.
Press OK to confirm of ESC to cancel
4.
Press MEAS to return to the measurement screen
15.1.2 Conducting an AUTO SET
There are two ways to access the AUTO SET function and these are described below. Method A is the
preferred method (it is quicker and easier). Before you use either method, ensure that you have previously
entered a value for ALEN / APPROX. LEN.
Method A
:
1.
Apply a drop of couplant to the bolt or transducer, and attach the transducer to one end of the bolt.
Rotate the transducer clockwise and counter clockwise applying a small amount of pressure to
eliminate any excess couplant between the transducer and the surface of the bolt. Remove and
replace the transducer twice in the exact same location on the bolt, rotating it each time to obtain the
minimum value measured.
Be sure to always place the transducer in the same location. This will help to eliminate any potential
measurement errors caused by changing the sound path.
2.
Press AUTO SET.
The display settings are adjusted automatically and the waveform is brought into view on the
measurement screen.
Method B
:
1.
Press MENU, scroll to the UTIL menu and then highlight AUTO SET.
2.
Apply a drop of couplant to the bolt or transducer, and attach the transducer to one end of the bolt.
Rotate the transducer clockwise and counter clockwise applying a small amount of pressure to
eliminate any excess couplant between the transducer and the surface of the bolt.
Be sure to always place the transducer in the same location. This will help to eliminate any potential
measurement errors caused by changing the sound path.
3.
Press ENTER.
The display settings are adjusted automatically and the waveform is brought into view on the
measurement screen.
4.
Once the waveform is displayed, press MEAS to return to the measurement screen.
15.2 ALARM MODE
Your gauge includes an Alarm Mode. You 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).
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 LO LIMIT and ALARM HI LIMIT. 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 STATUS and use LEFT and RIGHT to toggle the alarm on or off.
2.
Press MEAS to return to the measurement screen
