Operating Instructions
1. Insert the ultrasonic sensor into the probe connectors on the meter.
2. Press the Power button to turn the meter on.
3. TheLCDwilldisplay"0"andtheselectedunitofmeasure.
Initial Calibration
1. Placeasmalldropofcouplinggel(R7950)onthe5mmcalibration
test block.
2. Press the CALbuttonand"CAL"willappearonthedisplay.
3. Place the sensor on the calibration test block while ensuring the
coupling indicator appearsonthedisplayandthecouplingLED
turns on.
4. Depending on the selected unit of measure either "5.0 mm"
(or"0.197in")and"CAL"willashinterchangeablyonthedisplay.
5. While continuing to hold the sensor on the calibration test block,
press CAL again to save.
6. Calibration is now complete and the ultrasonic sensor can now be
removed from the calibration test block.
Note: Results from the calibration procedure will automatically save in the
meter. It is not necessary to calibrate the meter each time the unit is powered
on unless measurements appear to be inaccurate. The calibration procedure
conrms both the meter and ultrasonic sensor are functioning properly.
Material Mode Selection
Selecting Pre-loaded Materials
The meter has been pre-loaded with 11 common materials to allow for
quick setup and testing. In order to select the appropriate setting, follow
steps 1 through 4 below.
1. While the meter is on, press the SELECT button.
2. The display will either indicate "CdXX" or "XXXX". "Cd" stands for
code and "XX" is the pre-loaded material number which ranges from
1 to 11 as shown in the table below.

4. Press the or arrows to select the desired material code.
Press the SELECT button to conrm your selection. The display will
show "0" conrming the material has been selected. If you select a
material code without conrming the selection the meter will auto-
matically resume normal operation after a few seconds.

Measuring Procedure
Once the material has been selected, follow steps 1 through 4 below to
perform a measurement.
1. While the meter is on, press the mm/inch button to select the cor-
rect unit of measure.
2. After applying coupling gel on the material, place the sensor rmly
against the desired measurement area.
Note: For most applications a single droplet of coupling gel is sufcient.
3. Verify that the Coupling Indicator appears on the display and the
couplingLEDlightturnson.
4. TheLCDwilldisplaythemeasuredvalueandwillholdthisvalueuntil
a new measurement is taken or until the unit is turned off.
Note: If the coupling indicator does not appear on the display, or the
measured values appear to be erratic, verify that there is an adequate
amount of coupling gel in between the ultrasonic sensor and the material
undertest.Itisalsoimportantthattheultrasonicsensorsitsatagainst
the material.
Auto Power Off
To preserve battery life, the meter is programmed to turn off after
approximately 1 minute of inactivity.
Setting the Sound Velocity for a Known Material
If the material under test is not pre-loaded, the sound velocity of the
material under test can be entered. To enter the appropriate sound velocity,
follow steps 1 through 9 below.
1. While the meter is on, press the SELECT button.
2. The display will either indicate "CdXX" or "XXXX".
3. Press the or arrows to scroll through the material codes until
you see the 4-digit value.
4. This 4-digit number represents the last set sound velocity of a material.

5. Press the SELECT button to conrm your selection. The display will
show "0" conrming the material has been selected. If you select a
material code without conrming the selection the instrument will
automatically resume normal operation after a few seconds.
6. Press the VEL button and the display will show the last saved sound
velocity measurement.
7. The sound velocity can be adjusted by pressing the or
arrows to match the sound velocity for the material under test as
shown in the table below.

velocityvalueby100m/s.
9. Press the VEL button to conrm your selection. The display will show
"0" conrming the sound velocity has been set. If you set a sound
velocity without conrming the selection the meter will automatically
resume normal operation after a few seconds.
Determining the Sound Velocity for a Material with a
Known Thickness
The sound velocity of a material can be measured using a test piece with
a known thickness. In order to determine the sound velocity follow steps 1
through 3 below.
1. Measure the test piece with a caliper or micrometer to conrm
the thickness.
2. Repeat steps 3 through 9 from the "Setting the Sound Velocity for a
Known Material" section above.
3. Once the sound velocity has been set, proceed with testing.
