Calibration steps:
1) Long press
to enter the calibration mode.
"Please Calibrate" will show on the screen.
2) Refer to Figure 1 and Figure 2 in 6.2 Single
Measurement to evenly smear the coupling agent on
the surface of the standard thickness block. Press
the probe on the coupling agent to make it tightly contact
with the block surface. (Note: the coupling agent should
not be too thick. Otherwise the gauge will count the
thickness of the coupling agent, resulting in calibration
errors).
3) Press
to save the calibration data. (Note: Before
pressing , the value displayed might not be 4mm. When
the value is stable, press . After calibration, the displayed
value should be within the range of 4±0.04mm,
otherwise recalibrate).
6.6 Sound Velocity Measurement
Different materials have different sound velocities. The
materials and velocities listed in Appendix A are for r
eference only.This function is used to measure the sound
velocities of materials. The steps are as follows:
1) First calibrate the gauge.
2) Use a caliper to measure the thickness of
the workpiece.
3) Use the gauge to measure the thickness of the
workpiece.
