1. Preface
Please read the following information carefully
before using the meter. The coating thickness guage
is designed to measure the coating thickness on a
magnetic metalic matrix, can be widely used for
manufacturing, metal machining, chemical industry,
commodity inspection and so on. It is according with

The meaning of the symbols represented by the
following：
1. Display zone
2. Thickness units
3. Coupling sign
4. Indication to low voltage of the batteries
5. Number of standard thickness piece
Ⅵ．O peratio n i nstru ction
1. Press button “ON/OFF” , the meter displays 0. Waiting
for five minutes or more to get the meter steady.
2. Put the probe on the coating to be tested, Press it
gently and don’t dither. When a coupling sign appears,
the thickness of the coating displays. If coupling is
not good or the probe dithering, the coupling sign and
thickness don’t display.
3. When taking the probe out from the coating, the
coupling symbol disappears, but thickness keeps
displaying.
4. Press button µm/mil, thickness unit “µm” changes into
“mil” or contrarily.

05
5. To turn off:
When the meter is working, pressing button ON/OFF
will get shutdown immediately.
6. Automatic shutdown
When the meter is working, and stop to press button
or stop to measure for fifteen minutes, shutdown will
occur automatically.
Ⅶ． C alibrating th e m eter
1. The meter is based on the principle of electromagnetic
induction. Before leaving the factory, it had been
calibrated on the martensite stainless steel block that
is as an accessory
.
2. When the base material to be tested is different from
the martensite stainless steel block in the accessories,
user must calibrate the meter on the material to be
tested.
3. When changing a new probe, or the probe is abrased
or the meter is used for a long time, user need to
calibrate it.
06
4. The method of calibrating is following：
a. Press µm/mil then press ON/OFF buttons
simultaneity. The main display section of the meter is
0000, the lower left quarter is sample 0. It indicates
thickness 0 will be calibrated. Waiting for five minutes
or more to get the meter steady. Put the probe directly
on the metallic matrix without coating and press it for
two seconds no dithering. Then press button µm/mil
to perform calibrating of thickness 0 (the probe keeps
to press no dithering when Adjusting) . The main
display section changes into 50µm, the lower left
quarter changes into sample 1. It indicates that the
thickness of sample 1 will be calibrated. The probe
can be taken up.
b. Accoding to the thickness marking on the sample
1,press button ▲ or ▼ to change digitals of the main
display section untill it is equal to the value of the
sample 1. Lay the sample 1 on the metallic matrix,
then put the probe on them and press it for two
senconds gently, then press button ìm/mil to do
calibrating of the thickness of sample 1 (the probe
keeps to press no dithering when Adjusting). The
main display section changes into 125ìm, the lower

best dose on a workpiece that don’t smear any
coating.
Ⅷ．Notices
1. When calibrating on a metallic matrix and
measurement on another kind metallic matrix, the
error of measurement might be more than the rating
value. A material dealt with heat treatment or cold
working, its magnetism might change, calibrating had
2. The meter can not measure on the base that is
non-magnetic material, such as copper, aluminum
etc.
3. When power on, waiting for five minutes or more to
get the meter steady, then calibrating or measuring to
insure its accuracy.
4. When measuring on a thin base under 1mm, calibrate
the meter on the material with the same thickness.
When the basal thickness is more than 1mm, a
change of the basal thickness does not affect
measurement.
5. Don’t calibrate or measure on the fringe of a
workpiece.
07
left quarter changes into sample 2 . It indicates
the thickness of sample 2 will be calibrated. The probe
can be taken up.
c. Imitating the step b , perform calibrating of the
thickness of sample 2, sample 3, sample 4, sample 5.
At last, sample 6 displays. The thickness of sample 6
is equal to the sum of sample 3+ sample 5, press
button ▲ or ▼ to change digitals of the main display
section untill it is equal to the sum of sample 3+
sample 5. Lap over the sample 3 and sample 5, place
them on the metallic matrix, than put the probe on
them and press it for two seconds gently, then press
button µm/mil to perform calibrating of the
thickness of sample 6 (the probe keeps to press no
dithering when Adjusting). The meter displays OFF
finally.
d. Press ON/OFF button to end calibrating.

2. Mounting battery and probe
Remove the battery cover on the back and put in
three 1.5V AAA batteries according to the mark on
the shell to insure putting batteries in correctly, then
close the battery cover. Insert the plug of the probe
into a socket on the top of the meter.
Ⅸ. M aintenance
1. CLEANING INSTRUCTIONS
The meter may be wiped down with a wet sponge or
cloth using a mild water based detergent or
anti-bacterial soap and rinsed under a gentle stream
of cold water.
NOTE:
This unit is not designed for complete submersion or
washing in water.
09
10. When battery voltage is too low to work, a battery
symbol appears on the screen. It reminds you to
change new batteries.
11. When you do not use the meter for a long time,
please take out batteries to avoid damaging the meter
by electrolyte.
12. Don’t store the meter in a high temperature or wet
place.
13. After power off, to turn power on again, wait for five
seconds.
might be disturbed.
6. When calibrating on a plane, measurement is on a
curved surface, the error might be more than the
rating value.
7. Don’t press the probe with big force to avoid that the
Sample distortion brings an error.
8. The Samples or the coating of a workpiece is not
entirety even, might increase display error.
9. In a strong magnetic environment, measurement
