GAUGE
This Thickness Meter is small in size, light in
weight, easy to carry. Although complex and
advanced, it is convenient to use and operate.
Its ruggedness will allow many years of use
if proper operating techniques are followed.
Please read the following instructions carefully
and always keep this manual within easy reach.

1.FEATURES
• Used the exclusive Micro-computer LSI circuit and crystal time base to offer high
accuracy measurement.
• With high power of emission and broad band of receiving sensitivity, the gauge can
match probes of different frequencies. That makes it easy to measure the rough
surface, even cast iron. It is widely used in almost all kinds of industries.
• Applicable to measure the thickness of many materials, e. g. Steel, Cast iron,
Aluminum, Red copper, Brass, Zinc, Quartz glass, Polyethylene, PVC, Gray cast
iron, Nodular cast iron.
• Automatic power off to conserve power.
• Can communicate with PC computer for statistics and printing by the optional
cable and the software for RS232C interface .

4. MATERIAL SELECTION
4.1 Press the power key 3-4 to turn on the unit.
4.2 Press the Material Selection key 3-5 and the display 3-2 will show the code ‘cdxx’
or ‘xxxx’. ‘cd’ is the abbreviation for’ code’ and ‘xx’ is one numberamongOl~ll. ‘xxxx’
is a 4-digit number which is the sound velocity of material defined by the user. The
‘cdxx’material relationship is as follow.
No. Code Material

4.3 Press the Plus key 3-6 or Minus key 3-9 to select the material code to measure and
then press the Material Selection key to confirm. The display will show ‘0’. If you select
a material code but do not confirm the selec.tion, the code will automatically change
to ‘0’ after several seconds. In such case, the meter will still reserve the material code
before exiting.
4.4 A 4-digit number will be shown on the Display if pressing the Plus key 3-6 when
displaying ‘cdll’ or pressing the Minus key 3-9 when displaying ‘cdO 1’. The 4-digit
number is last sound velocity to define by the user. By selecting this velocity, you could
measure the thickness of the same material as last.
4.5 It is unnecessary to select the material code once the material code is confirmed
(automatically stored to the memory of the meter) unless the material to measure is
different from that before.
4.6 To browse the material code selected, if only press the Select key 3-5. To quit
browsing, if only press the Select key 3-5 again or wait till the code automatically change
to ‘0’ after several seconds or the meter will automatically return to measurement state
if measuring.

5. CALIBRATION
5.1 Drop a little oil on the 5 mm standard block 3-12.
5.2 Press the Calibration key 3-8, the ‘CAL’ be shown on the Display. ‘CAL is the short
for calibration.
5.3 Press the sensor 3-7 on the standard block. The coupling symbol ((
•
)) is on if
coupling well. ‘5.0’ mm (or ‘0.197’ inch) and ‘CAL’ will be shown on the Display in tum.
When steady, Press CAL key 3-8 to confirm and then the unit return to the state of
measurement.
5.4 The calibration result will be auto-saved to the unit once confirmation. It is
unnecessary to calibrate often unless you suspect the accuracy of measurement.
6. MEASURING PROCEDURE
6.1 Press the power key 3-4 to tum on the unit.
6.2 Press the mrnlinch key 3-3 to select the right measurement unit.
6.3 Press the Sensor 3-7 onto the material surface to measure on the premise that the
material code selected is right. Be sure that coupling is well and the symbol ((•)) is on.
The reading on display is the measurement value.
6.4 The reading is held till a new measurement value is coming. The last value is held
on the display till the power is off.
6.5 2 modes to tum off the power. Manual off at any time by pressing the power key or
Auto power off after about 1 minutes from last key operation.
7. MEASURING BY VELOCITY SETTING
7.1 Press the VEL key 3-13 and the display shows the velocity set last time.
7.2 How to measure its thickness by the velocity known? The velocity can be changed
by pressing the plus key or minus key to the value of known velocity. The increment is 1
Om/s every time when pressing the plus or minus key. And the increment is 1 OOm/s if
depressing the key form ore than about 4 seconds.
7.3 Drop a little oil onto the material to measure and press the Sensor 3-7 onto the
surface. The reading on the display is the thickness if coupling well. So if we have known
the velocity of a certain material, it is easy to measure the thickness by 7 .2.
7.4 How to measure the thickness by a sample of known thickness? Just get a sample
of known thickness. Then repeat 7.2 and 7.3 till the measurement value is totally same
7
as the known thickness. In such a case, the set value is the velocity of the material to
measure, by which you can measure any unknown thickness of same material.
7.5 To browse the velocity, if only press the VEL key 3-13. To quit browsing, if only
press the VEL key 3-13 again or wait till the meter automatically show’ 0’.
7.6 By use of velocity measurement, it is easy to measure the thickness of any hard
materials.
8. BATTERY REPLACEMENT
8.1 When the battery symbol appears on the display, it is time to replace the batteries.
8.2 Slide the Battery Cover away from the instrument and remove the batteries.
8.3 Install batteries paying careful attention to polarity.
