3.3 Thickness measurement
Put few coupling agent on the area to be measured to couple the
transducer with the hardware/workpiece, LCD will display the
thickness reading. During measurement, indicates a well
coupling, if the icon flashed or not shows means a poor coupling,
after remove transducer, the reading will hold without .

3.4 Velocity measurement
With a given thickness to read out velocity of material: Obtains
the thickness of material by using vernier caliper / micrometer,
then couple the transducer with that sample material until a
thickness displays, press or to adjust the reading match
the thickness by caliper/micrometer, then press to display
the velocity and save in current velocity memory unit.
REMARK: 1 To select / adjust the velocity as the table of
sound velocity for thickness measurement, but the actual
velocity in the hardware / workpiece will slightly different, in
this case the reading of thickness not very accurately.
2 Select a sample block with same material to the hardware
or workpiece to be measured to read out the velocity, then apply
this velocity for thickness measurement, in this way the reading
of thickness much more accurately.
3.8.Data delete
1 Press for 3 second will clear all stored data,
symbol will show on LCD.
2 In data recall mode, press will delete current
stored data. After delete data, the vacant memory will display
---- on the LCD.
3.9 Low battery indication
When battery power down to 3.3V 0.2V, the low battery iocn
will display, please replace the batteries for further
measurement.
3.10. Back light selection
In power off statu, press + to turn on the unit, select back
light on/off function. The back light will be actived for 10 seconds
in operations.
3.11. Turn off: Press to turn off/on the unit. The unit will be
auto turn off in 1 minute without any operation.
Remark: Press and to adjust/select different velocity
or thickness.
