Getting Started (A condensed guide for those who
hate to read manuals)
OK, here it is. A quick overview of the AccuTrak VPE-2000 written for those who
will probably read nothing else. This will give you a basic understanding of the
unit’s operation and function, however we
STRONGLY recommend that you
read the complete manual. Or, at the very least, continue to read the following
section concerning the principles of operation.
Leak Detection...
Use the airborne sensor for detecting pressurized gas leaks and vacuum leaks.
Remember, leaks must be turbulent to detect ultrasonically.
1. Insert the headset jack into the plug on the side of the instrument (I.), and
push the power button (D.).
2. Depress the mode select button (F.) until the alphanumeric display (A.N.D.)
reads “AIRH” (This stands for airborne sensor at high ultrasonic
frequency)
then press the
“
”
or
“
”
to activate the airborne sensor (A.). “AIRL”, or Low
frequency ultrasonic is also available, and is activated the same way. Once
activated you will begin to hear a translation of any ultrasonic sound present
in test area, and the LED bargraph meter will display the strength of the
corresponding signal. The highest LED will hold its place for 5 seconds
before resetting its position. This will help guide you toward the leak, where
the sound is most intense. The instrument always resets itself so that
sensitivity is the active mode. If the LED bargraph meter is at maximum,
reduce the sensitivity by simply pressing “
“ until it reads “10” or less, then
continue.
3. To adjust the volume, press the mode button once. The A.N.
D reads “VOL”.
Then use the
“
”
and
“
”
buttons to make the adjustment. The
alphanumeric display will read “V 000”. Volume, as with all numerical values,
has a range of 0 to 255.
4. Listen for the leak. A gas leak will sound like a harsh rushing noise, or high
intensity hiss. This sound will increase as the instrument is drawn toward the
leak point, and will clearly disappear as the sensor is turned away.
5. For more detailed information on specific applications,
refer to page 10 of this
manual.
