Press key to turn on the gauge.
Probe zero
The gauge does an automatic zeroing of the transducer thus
eliminating the need for an on-block zero. And then the gauge
came into the measurement mode directly.
Please make sure the transducer is not coupled to the test
piece when the gauge is first turned on and that there is no
coolant on the end of the transducer. The transducer should
also be at the room temperature, clean without any noticeable
wear.
Backlight
Press to turn on / off the backlight.
Parameters setting
Measurement mode
Press into the measurment mode setting.
Press or to select desired measurment mode.

measurment modes, they are T-E Mode and Scan.
T-Mode
STANDARD - It is available for the normal measurement.
MINIMUM -The gauge will catch and display the minimum
measured thickness during one measurement process. It is
available for measuring the thickness of curve surface or
pipe.
6
DIFFERENCE - The gauge will display a thickness value as
an absolute number of what has been inputted. For
AVERAGE - The gauge will display the average thickness of
2-9 measurements.
LIMITATION – The gauge will alarm you of low or high
thresholds via audible sound.
SCAN
The gauge will alarm for each fast measurement. And will
display the all measured thickness upon the complete
measurement finished. It is available for measuring the
thickness of test piece with high temperature surface.
Press to confirm selection.
Press to Esc. Menu and into the measurment.
Other parameters setting
Press and then press into the setting.
Velocity rate
1)Velocity Setting
Press into“ VEL. SETTING” state.
There are 9 velocities for materials pre-stored in gauge.
You can select one by pressing or .
Press to confirm.
2)Velocity measurement
Measuring the sample which thickness is known.
Press key into“ Velocity measurement ”state.

Press or to up and down the value of velocity to
determine the thickness as the same as the value of
sample that is measured.
Press key to confirm.
Resolution
Press key into“ Resolution ”.
Press or to select resolution and unit.

example, input value = 5.00mm and the real thickness is
5.03mm, the display will show diff 0.03mm. If the real value
is 4.97 m, the gauge will display, -0.03mm.
3)Velocity store
After you set the velocity, the instrument can store the
velocity value.
