Introduction
1).Introduction
This unit is an intelligent handheld product, whichadopts
ultrasonic measuring principle,and is controlledby micro
processor, providesquick and precisemeasurement of
thickness for mostof industrial material.This unit is widely
used in variousprecise measurement fordifferent hardw-
are /parts inindustrial realm; oneof its importantapplica-
tion is tomonitor the levelof thickness-decreasing during
operation of variousand pressure container. Diffusely
applied in manufacturefields, metal processing,and
commercial inspection.
2).Scope of application
This unit is suitable formeasuring materials thatare good
ultrasonic conductor suchas metal, plastic,ceramic,
glass etc., aslong as themeasured part intwo parallel
surfaces for measurementof thickness. This unit isnot
suitable for castiron due toits big crystalloidcomposition.
3).Features and functions

2. Operation Instruction
1). Connectthe transducer withthe unit, thenpress to
turn on. LCDwith full screendisplay with backlight for
0.5 second, thenLCD display thelast applied sound
velocity. Now the unitis ready foruse.
2).Sound velocity selection
Press twice toentre sound velocityadjustment with
icon blinking, pressup or downkey to selectyour
desired velocity, to finishthe selection by press .

3).Sound velocity adjustment
Press onece to entre velocity adjustment with stored
velocity unit blinking, press up or down key to adjust the
velocity to obtain desired value, then press to finish
the adjustment. The revised velocity will be saved into the
unit.
4).Calibration
On normal status,press for 3second, then CAL
symbol shows inLCD with 5900 m/s velocity and 4.00 mm
display.
Use the standardsample block forcalibration, until CAL
symbol disappeared, pressup or downkey to entremea-
surement mode.

Thickness Measurement
Put few couplingagent on thearea to bemeasured to
couple the transducerwith the hardware/workpiece. LCD
will display thethickness reading. Duringmeasurement,
indicates a wellcoupling, if theicon flashed ornot shows
means a poorcoupling, after removetransducer, thereading
will hold without .

REMARK:
1).Toselect / adjustthe velocity asthe table ofsound velocity
for thickness measurement.But the actualvelocity in the
hardware / workpiecewill slightly different, in this case the
reading of thicknessnot very accurate.
2).Select a sampleblock with samematerial to thehardware
or workpiece tobe measured toread out thevelocity. Then
apply this velocityfor thickness measurement.In this way
the reading ofthickness much moreaccurately.
