=
When take the probe out from the measured object,
the coupling symbol disappears, but thickness keeps
displaying.
=
At the state of displaying thickness and do not
measure, Press button
“mm/inch”,
thickness unit
“mm” changes into “inch” or contrarily.
=
At the state of displaying thickness and do not
measure, Press button
“Select”,
to display
ultrasonic wave speed, thickness will disappear.
=
Material a-e (digit 13~17) are offered to user to
set own material. Press button or , its velocity
is adjustable
D) Press button
“Select”,
the ultrasonic wave
velocity of user’s material will appear. When
shut the meter down, the ultrasonic wave velocity
will be saved into a memory.
8) To set power off :
When the meter is working. Pressing button On/Off
will get shutdown immediately.
=
If user do not know the ultrasonic wave velocity of
own material, can test it by oneself.
A) Make a block with measured material (the more
thick the block, the more exact the result is),
measure its thickness by a calipers carefully.
B)
Select
anyone of material a~e, and measure its
thickness display steady, take the probe out from
the block.
C) Press button or to change the digits until
it is equal to the value measured by the calipers.
9) Automatic shutdown :
When the meter is ON, and stop to press button
for five minutes, shutdown will occur automatically.

Press button “
Select
” to choose a material you
will measure. A number displays on the bottom of
the screen to indicate the material. The numbers
correspond to the material listed in table (1). Smear
a little of coupling paste on the surface of the
measured object, put the probe on and press it. A
coupling symbol would appear if coupling is all right.
Synchronously the thickness of the measured object
would display instead of ultrasonic wave velocity. If
Coupling isn’t good, the coupling symbol will not
appear and can not get thickness.
