3. Operating Instructions
1> Connect the transducer with the Ultrasonic Thickness
Gauge unit, and press to turn on the device. The LCD will
display flash the full screen for 0.5 second with the back light
present, followed by the icon which will continue scanning
for 2 cycles. After completing the startup procedure, the LCD
display will set up the last applied sound velocity setting,
indicating the gauge is ready for use.
2> Press
VEL
to enter your sound velocity adjustment, and
press or to select your desired velocity (There are 12
velocity settings stored in this unit). If you need to customize
the sound velocity, during the adjustment press
VEL
again to
enter velocity revision, while pressing or to revise the
velocity.
VEL
and m/s icon will continue blinking until set.
Press
VEL
to confirm to save the revised velocity, and the
unit will go back to normal status (
VEL
and m/s icon will no
longer blink)

3.2. Calibration
A calibration should be made whenever the batteries or
transducer has been replaced. This calibration is important to
ensuring precise measurement. If necessary, this step should
completed when the accuracy of measurement is critical. Prior
to calibration, apply coupling agent on the standard calibration
piece supplied, and couple the transducer to the calibration piece.
Press
CAL
to enter calibration mode and the vertical bar will
keep scanning with
CAL
,
VEL
, m/s display, until the LCD display
4.0mm indicating the calibration is completed. After calibration,
sound velocity will return to your selected value, and be ready
to measure.
Get a measurement of sound velocity for a
specific known thickness of the material you are
measuring. Obtains the thickness of material
by using a vernier caliper / micrometer. Then
couple the transducer with that sample material
until a reading displays on the LCD. Remove
the transducer and press or to adjust
the reading to match the thickness by caliper/
micrometer, and then press
VEL
to display the
sound velocity and save it in current sound
velocity memory storage.
1>
Press and hold
STORE
for 2 second to enter
the data store mode,. The LCD will display
THICKNESS

mm
and an
M
icon as the first
memory unit. If the first memory unit is not
being registered, the LCD will display 0.0.
2>
Press or to select your desired memory
unit (1-10).
3>
After selecting the memory unit of choice,
the new measurement will be replace the
existing memory unit after you have taken your
new measurement.
Apply the coupling agent on the material to be measured to
couple the transducer with the material and the LCD display will
display the thickness reading.
Notes:
icon on the screen indicates proper coupling. If the
icon flashes or does not display you have not achieved proper
coupling. After removing the transducer, the reading will be held
and can be stored.
