Introduction
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.
Functions
“This device complies with the ISO- Norm 2360 as well as the DIN-Norm, ASTM,
and BS. This means that it can be used both under laboratory conditions and
under rough environmental conditions “in the field”.
“The F” probe measures the thickness of non-magnetic layers, e.g. paint,
plastic, enameled porcelain, copper, zinc, aluminum, chrome, lacquer layers,
etc.
These layers should be on magnetic materials such as steel, iron, nickel, etc.
This probe is often used to measure the thickness of galvanized layers,
lacquer layers, enamelled porcelain layers, phosphorescent layers, copper
plates, aluminum plates, alloys, paper, etc.
“The N- probe measures the 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.
“The FN measuring probe is a combination of both probes and is therefore
defined for both areas of application
“Automatic recognition of the carrier material
“Manual or automatic switch-off to conserve battery power.
“Metric/ imperic conversion of the measured values of µm/mil
“Two measuring modes: – single and continuous (S= single/ C= continuous)
“Wide measuring range and high resolution
” Can be connected to a PC for data transfer via RS 232 interface Cable and
software are available as optional accessories (ATC-01).

Measuring procedure
a) Switch on by pressing the on/off button 4-6. ‘0’ appears on the display
4-2. The TC 1250-0.1FN meter recognizes the setting of the last easurement
itself by the symbol ‘Fe’ (= F) for ferrous metals or ‘NFe’ (= N) for non-
ferrous metals shown on the display. It switches to the automatic measuring
mode, which also correctly recognizes and assigns the zero plate or any other
substrate itself.
b) Place the measuring probe 4-1 on the layer to be measured. The layer
thickness can now be read on the display. The reading result can be corrected
by pressing the plus key 4-4 or the minus key 4-5. For this purpose, the
measuring probe should not be in close proximity to the layer to be measured
or the zero plate.
c) To take the next measurement, simply raise the measuring probe 4-1 by more
than 1cm, the display will show “0” again and step b) will be repeated.
d) In case of possible inaccuracies in the measurement result, it is
recommended to adjust the measuring instrument before measurement, as
described in chapter 6.
e) On the one hand, the device can be switched off with the on/off button 4-6.
Otherwise, it switches itself off 80 seconds after the last key is pressed.
f) The measuring unit can be displayed in µm or mil. The changeover is made as
follows: – By pressing the changeover key 4-7 or – the on/off key 4-6 is
pressed and held until ‘UNIT’ is shown on the display and then the zero key
4-3 is pressed. The measuring unit changes over to the other one when
the on/off key is released again. This process takes a total of 7 seconds
(from pressing the zero or on/off button).
g) To change to the measuring mode from ‘simple’ to ‘continuous’ or vice
versa, the zero or on/off key 4-6 must be pressed and held down until ‘SC’
appears in the display. Then the zero key 4-3 is pressed. The symbol ((-))
stands for the continuous measuring mode and ‘S’ for the simple measuring
mode. This process takes 9 seconds (from pressing the on/off button).

6. Zero adjustment
a) The zero adjustment for ‘Fe’ (=F) and ‘NFe’ (=N) should be done separately.
The iron zero plate is taken when ‘Fe’ is read on the display, while the
aluminium zero plate is taken when ‘NFe’ is read. The measuring probe 4-1 is
now carefully placed on the zero plate. The zero/on/off key 4-6 is pressed and
‘0’ is shown in the display without lifting the probe. Attention: The zero
adjustment is useless if the measuring probe is not directly on the zero plate
or another, uncoated carrier material. b) A suitable adjustment foil, which
corresponds approximately to the measuring range, must be selected. (c) This
standard alignment foil is positioned on the supplied zero plate or on the
appropriate uncoated substrate for the forthcoming tests. d) Carefully press
the measuring probe 4-1 in the middle of the standard foil and then lift it
off again. The reading on the display corresponds to the measured value of the
layer thickness. This reading can be corrected by pressing the plus key 4-4 or
the minus key 4-5. This should be done if the probe is not in the nearer
vicinity of the zero plate or the corresponding carrier material. e) The
procedure described in d) should be repeated until the result is correct.

e) The procedure described in d) should be repeated until the result is
correct.
Battery replacement
a) When the battery symbol “+/-“ appears on the display, the batteries should
be replaced.
b) The battery cover 4-8 is removed from the meter and the batteries are
removed. c) The batteries (4×1.5 V AAA/UM-4) are inserted by observing the
polarity when inserting them. d) If the device is not used for a longer period
of time, the batteries should be removed.
Adjusting foils
This instrument includes an adjustment foil set with different foils and measuring ranges, but always covers the measuring range from 20 to 2000µm. These are also available as optional accessories, article ATB-US07
General notes
a) The measuring instrument should always be adjusted on the base material
used for the actual measurement, if possible, instead of on the supplied zero
plate F made of steel or N made of aluminium. This makes the measuring
accuracy more accurate from the outset.
b) The measuring probe may wear out. The lifetime of it usually depends on the
number of measurements and the roughness of the layer to be measured. The
replacement of a measuring probe should only be carried out by qualified
personnel can be carried out.
Restore factory settings
a) It is recommended that the factory settings be performed in the following
cases:
• no more measurements can be made at all
• the measuring accuracy is impaired due to drastic changes in the environment
in which the measuring instrument is used
• After replacing the measuring probe
b) Procedure:
The factory settings include both the settings for “Fe” (F) and for “NFe” (N).
Please note which symbol is shown on the display. Only one setting at a time
can be made, as follows:
• Press the on/off button 4-6 and do not release it until the display shows
“CAL”. It takes about 5 seconds from the start of this button operation until
CAL is displayed.
The measuring probe 4-1 is carefully pressed onto the corresponding carrier
material.
Then the zero key is pressed, which is accompanied by a beep. When NF:H
appears on the display, the measuring probe 4-1 is raised by more than 5 cm.
Then the zero button is pressed again and the meter returns to the measuring
mode. The factory settings are now complete.
Note: This process should always be completed within the following 6 seconds.
Otherwise, it will be automatically interrupted by the unit and the reset will
be invalid.
Notes
With the LN function, the linearization of the measuring instrument specified
by the calibration can be changed. However, it is strongly recommended not to
make any changes to the LN value, as this change will lead to deviating
measurement results. Any change in the Ln value can significantly affect the
measuring accuracy. This value should only be set by qualified personnel.
In general, the larger the Ln value, the smaller the reading result for the
same layer thickness. A small change of the Ln- value causes a large change in
the reading result in the upper measuring range (at 500µm/ 20mil).
Thus the Ln value is to be corrected:
Pressing the on/off button: It takes about 11 seconds from the beginning of
pressing the on/off button.
Its value can be changed by pressing the Plus or Minus key after ‘LN’ appears
in the display and releasing the On/Off key. The value is stored and then the
zero key is pressed.
A: The reading result in the lower area is corrected by pressing the Plus or
Minus key.
B: The Ln value is increased if the reading result is correct in the lower
range (e.g. 51µm) but too large in the upper range (e.g. 432µm). In contrast,
the Ln value is reduced if the reading result is correct in the lower range
(e.g. 51µm) but too small in the upper range (e.g. 432µm).
C: This procedure of A. and B. is repeated until the reading result is
satisfactory in its accuracy for each distance foil.
