1. Introduction
1.1 General description
This coating thickness gauge is small, light and handy. Although it has complex and
advanced equipment, it is convenient and easy to use.
Its robustness allows it to be used for many years, provided that all instructions in this
manual are carefully followed.
Therefore please keep them always within reach!
Note: It is strongly recommended to adjust the new meter before first use, as
described in chapter 6. This will result in a higher measurement accuracy from
the beginning.
2. Functions
"This device complies with ISO 2178 and ISO 2361, as well as DIN, ASTM and BS
standards. This means that it can be used both under laboratory conditions and under
rough environmental conditions "in the field".
"In F mode, the thickness of non-magnetic layers, e.g. paint, plastic, enamelled
porcelain, copper, zinc, aluminium, chrome, lacquer layers etc., is measured.
These layers should be on magnetic materials such as steel, iron, nickel, etc. This test
method is often used to measure the thickness of galvanised layers, lacquer layers,
enamelled porcelain layers, phosphorescent layers, copper plates, aluminium plates,
alloys, paper etc.
"In the N- mode, the layer thickness of non-magnetic layers on non-magnetic metals.
It is used to measure anodizations, lacquer layers, glazes, colours, enamel, plastic
layers, powder coating etc. These should be on non-magnetic substrates such as
aluminium, sheet metal, non-magnetic stainless steel and others.
"Automatic recognition of the carrier material
"Manual or automatic switch-off to conserve battery power.
"Two measurement modes: -single and continuous
"Metric/imperial unit conversion
"Wide measuring range and high resolution
"The backlit display allows accurate reading
"Up to 99 measured values can be stored.
"A statistics function is available
" Can be connected to a PC for data transfer via RS 232 interface for statistical
purposes. Cable and software are available as optional accessories (ATC-01).

5. Measurement procedure
4.1 The power key 3-3 has to be pressed to switch on the instrument. `0` appears on
the display 3-2.
Both instruments, TF and TG, will recognize the mode of the last measurement itself
by the symbol appearing in the display `Fe` (= F) for ferrous metals or `NFe` (= N) for
non-ferrous metals. The instrument changes into the automatic measurement mode,
which also is able to recognize and assign also the zeroing plate or any other base
material.
4.2 The sensor 3-1 has to be placed onto a coating layer to be measured. The reading
on the display is the thickness of the coating layer. This can be corrected by pressing
the Plus- key 3-4 or the Minus- key 3-5. For doing this, the sensor should be kept away
from the measured object or the base plate for at least 5 cm.
4.3 To perform the next measurement, the sensor 3-1 has to be lifted for more than
1cm, “0” will be displayed and step b) has to be repeated. The instrument memorizes
the continuous measured value automatically with statistic measurement times.
Meanwhile, the Max, Min and average value will be displayed.
4.4 To avoid any appearing incorrect measurement values, we recommend adjusting
the instrument before starting with the measurements, as described in chapter 9.
4.5 To change the measurement unit from „µm“ to “mil” or vice verse, the Power-key
3-3 has to be pressed and not released until “UNIT” is shown on the display. Then the
same key 3-3 (this time Zero-key) has to be pressed.
4.6 To change the measuring mode from `single` to `continuous` or vice verse, the
Power-key / Zero –key 3-3 has to be pressed and not released until `SC` appears on
the display. Then the Zero- key 3-3 (the same one) has to be pressed.
The symbol “STATS” represents the continuous mode and `S` represents the single
mode.
6. Statistics
This instrument calculates and displays a statistical analysis of readings while the
measurements are taken.
The statistics available are:
•Last value
•Average value, marked by AVE
•Highest reading marked by Max
•Lowest reading marked by Min
•Number of measurements taken

TG_TF-BA-e-2020 7
To clear the statistical data before starting a new set of data, the Zero-key 3-3 just has
to be pressed and released. In measurement mode, which is marked by SV, the last
value can be deleted by pressing the DEL-key. Statistics is re-calculated and displayed
again.
7. How to store and recall readings
6.1 The measurements taken are automatically saved in the memoryof the instrument.
The memorized data can be shown and browsed by pressing and releasing the READ-
key to enter into the browsing state, which is marked by “READ” on the display.
6.2 In browsing state, all the readings memorized can be recalled on the display by
pressing the Plus-key 3-4 or the Minus-key 3-5.
6.3 To delete only one memorized value in the memory; the reading to be deleted just
has to be located on the display by the Plus-key or the Minus-key. Then the DEL-key
has to be pressed and released. If “Err0” appears on the display, it means that there is
no reading to delete any more.
6.4 The Zero-key 3-3 has to be pressed to quit the measurement state.
8. How to delete readings
7.1 To delete a reading on the display, the DEL-key has to be pressed, no matter
whether you are located in the measurement state marked “SV” or in browsing state
marked “RD”. Browsing state can be entered by pressing the READ-key and
measurement state is entered by pressing the Zero-key.
7.2 To delete all measurements taken (readings) in the memory, the DEL-key has to
be pressed in measurement state marked by “SV” on the display for about 4 seconds
until the number of readings memorized becomes 0.
9. Transfer of readings to a PC
8.1 ATC-01 software has to be installed on the PC. During the installing process the
“continue”-button always has to be clicked.
8.2 The instrument has to be connected to the PC using the optional cable.
8.3 The Coating Thickness Gauge has to be switched on to ensure that the reading
screen is displayed.
8.4 The software has to be started and the instructions included with the software
Demo. EXE. have to be followed.

10.Calibration
9.1 Zero adjustment
Zero adjustment for `Fe` and `NFe` should be carried out separately. The iron base
plate has to be used if `Fe` is being displayed. The base plate of aluminium has to be
used if `NFe` is shown on the display. The sensor 3-1 has to be placed carefully onto
the base plate. Zero-key 3-3 has to be pressed and “0” will be displayed, without lifting
the sensor before.
Attention: The calibration is invalid if the sensor is not directly placed onto the
base plate or another uncoated material.
9.2 An appropriate calibration foil has to be selected according to the measurement
range.
9.3 The selected standard foil has to be placed onto the base plate or the uncoated
standard material.
Annotation: Please place the sensor at least with 3mm distance from the border of the
base plate.
9.4 The sensor 3-1 has to be pressed carefully onto the calibration foil and then lifted.
The reading on the display is the value measured.
This can be corrected by pressing the Plus- key 3-4 or the Minus- key 3-5 while the
sensor is removed from the base plate or the measured object.
9.5 Step 9.4 has to be repeated until the desired accuracy is achieved.
11. Battery replacement
10.1 If the battery symbol ``+/-`` appears on the display, batteries should be replaced.
10.2 The battery cover 3-9 has to be removed and batteries have to be taken off.
10.3 The batteries (2x1.5V AAA/UM-4) are to be installed correctly into the case, taking
care of polarity.
10.4 If the instrument is not to be used for an extended period of time, batteries have
to be extracted.
12.Adjustment foils

TG_TF-BA-e-2020 9
This instrument has included in delivery a set of adjustment foils with different foils and
thicknesses, whereupon the measurement range of 20 up to 2000µm will always be
covered. These adjustment foils are also available as an optional accessory, article
number ATB-US07.
13.Correct handling at Coating Thickness Measurement with
external sensors
The sensor has to be touched at the lower pole segment and it has to be pressed
slightly onto the test object.
The black chequered pole segment is movably seated on a spring. By means of the
spring, the sensor tip presses onto the test object with a defined force. This way,
measurement errors can be avoided.
It is recommended to perform several test measurements before the first use of the
instrument. In this way, further measurement errors can be avoided.
14.Trouble shooting
13.1 The instrument should always be calibrated on the uncoated base material to be
measured instead of the base plate included in the delivery. Like this, accuracy is more
precise from the beginning.
13.2 Sensors will eventually wear off. Life of the sensor will depend on the number of
measurements taken and how abrasive the coating is. Replacementof a sensor should
only be performed by qualified staff.
15.Restore factory settings
14.1 In the following cases it is recommended to restore factory settings:
- The instrument does not measure any more.
- Measurement accuracy is degraded caused by the abraded sensor or affected by
environmental conditions.
- After the replacement of a new sensor.
14.2 Procedure:
To restore factory settings includes both, setting of “Fe” (F) and of “NFe” (N).
It can be only performed one after another. The procedure is as follows:
14.2.1 It is always differentiated between the symbols „Fe“ and „NFe“. If „Fe“ is
displayed, factory settings will be done for „Fe“ type, and if „NFe“ is displayed, it will be
done for „NFe“ type.
14.2.2 The Power-on/ Power-off key 3-3 has to be pressed and not released

until `CAL` appears on the display. This lasts about 12 seconds from starting pressing
the Power-key.
14.2.3 If now NF:H appears in the display, the sensor has to be lifted for more than
5cm. Then the Zero- key has to be pressed and the instrument returns into
measurement mode. With this, factory setting is restored.
Comment: This procedure should always be finished within 6 seconds. Otherwise it
will be automatically cancelled and the restoration is invalid.
16.Annotations
15.1 All settings, including restoring factory setting, unit setting, S/C setting should be
finished within 6 seconds. Otherwise this procedure will be cancelled by the instrument,
it will quit and keep the status as before.
15.2 The linearization of the instrument, which is given by
the calibration, can be changed with the Ln- function. Linearization is commanded by
the Power-on/ Power-off key and it lasts about 14 seconds from starting to press this
button.
Nevertheless, it is strongly recommended not to perform any alterations of the value of
LN, because those alterations might lead to deviations the measurement results.
Any adjustment of the value of Ln will seriously affect the accuracy. This value
should only be adjusted by professional persons.
Generally said:
The bigger the value of Ln, the smaller the reading on the display for the same (coating)
thickness. Only a small change on the value of Ln causes a big change in the reading
of the upper measurement range (at 500µm/20 mil).
The value of Ln has to be adjusted as follows:
Press the Power-key: It lasts about 14 seconds from starting pressing this key. This
value can be changed by pressing the Plus- respectively the Minus- key after `Ln`
appears on the display and the Power-on/ Power-off key is released. This value is
saved and then the Zero-key has to be pressed.
A. The reading at low end is to be adjusted by pressing (confirming with)
the Plus-/ or the Minus-key.
B. The value of Ln is enlarged if the reading at low end (e.g. 51µm) is o.k., but the
reading at high end (e.g.432µm) is too big.
In contrast with this, the value of Ln is to be decreased, if the reading at low end
(e.g. 51µm) is o.k., but at high end (e.g. 432µm) it is too small.
C. This procedure from A. and B. has to be repeated, until the reading for every
calibration foil is satisfactory in its accuracy.
