7. Take another measurement of the test piece to verify if the thickness
reading is getting closer to the known thickness or not. If for some
reason it is now farther away than before, reduce the velocity a little
by pressing the
button. Check the thickness again to make sure
that you are getting closer. Continue adjusting the sound velocity until
the thickness reading is correct.
8.
Once you have reached the known thickness of the test piece, press
the
button to confirm your sound velocity setting. From this point,
the sound velocity is calibrated and you can now take measurements of
the same material with confidence.
Two Point Calibration
1. Select two standard samples of the same material to be measured,
among which one has a thickness equal to or slightly higher than the
tested piece, and the thickness of another test piece is slightly lower
than the tested piece.
2. Before carrying out 2-point calibration, turn off the "Minimum
Capture" function and erase the CAL data in the "Memory Manager".
3. Set the 2-point calibration to ON in the "System Setup" menu.
4. Press twice on the
button to return to the main display.
5. Press the
button at any time during measurement to enter the
2-Point CAL.
6. Measure the thinner standard test piece.
7. Remove the ultrasonic sensor from the test piece and use the
and
buttons to adjust the measurement to standard value.
8. Press the
button and the LCD will prompt to measure the
thicker piece.
9. Measure the thicker standard test piece.
10. Remove the ultrasonic sensor from the test piece and use the
and
buttons to adjust the measurement to standard value.
11. Press the
button when the two-point calibration is completed.
