Annotation: It is strongly recommended to calibrate
the new instrument before the first use, as described
in paragraph 5. By doing this, there will be achieved a
much better measurement result right from the start.
1. Features
»This instrument meets the standards of both ISO 2178,
ISO 2360 as well as DIN, ASTM and BS. It is suitable for
the laboratory and for use in “harsh field” conditions.
»The F mode measures the thickness of nonmagnetic
materials, e.g. paint, plastic, porcelain enamel, copper,
zinc, aluminium, chrome, laquer layers etc. These layers
are located on magnetic materials e.g. steel, iron,
nickle etc. It is often used to measure the thickness of
galvanizing layer, laquer layer, porcelain enamel layer,
phosphide layer, copper tile, aluminium tile, some alloy
tile, paper etc.
»The N mode measures the thickness of nonmagnetic
coatings on nonmagnetic materials.
It is used on anodizing, varnish, paint, enamel, plastic
coatings, powder etc. It can be applied on aluminium,
brass, nonmagnetic stainless steel etc.
»Automatically substrate recognition.
»Manual or automatically auto power off to conserve
batteries
»Two measurement modes: - single and continuous
»Data transfer to PC possible

Instruction Manual
4. Measuring procedure
4.1 Plug in the F- sensor or the NF- sensor according to
the measured object.
4.2 Press the power key 3-6 to switch on the instrument.
`0` appears on the display 3-2.
The instrument recognizes the sensor itself by the
symbol `Fe` (= F) or `NFe` (= N) which is indicated
on the display.
4.3 The sensor 3-1 is to be placed onto a coating layer to
be measured. The reading on the display is the thick ness of the coating layer. This can be corrected by
pressing the Plus- key 3-4 or the Minus- key 3-5
(Offset- Accur function)
For doing this the sensor should be away from
the measured object or the base plate.
4.4 For the next measurement just lift the sensor 3-1 for
more than 1cm and step 4.3 is to be repeated.
4.5 In case of inaccuracies to the measurement result it is
recommended to calibrate the instrument before
measuring as described in part 5.
4.6 The instrument can be switched off by pressing the
Power key 3-6. The power will switch itself off
50 seconds after the last operation.
4.7 The measurement unit can be indicated with `µm` or
`mil`: To convert:
A by pressing the conversion key 3-7 or
B by pressing the Power key and not releasing it
til `UNIT` appears on the display. Then the Zero
key 3-3 is to be pressed. All in all this operation
lasts about 7 seconds.
4.8 To change the measuring mode from `single` to
`continuous` or vice versa,
A The SC- key 3-10 is to be pressed or
B The Power-key 3-6 is to be pressed and not
released until `SC` appears on the display. Then
the Zero- key 3-3 is to be pressed. The symbol ((•))
indicates the continuous mode and `S` indicates the
single mode. This operation lasts 9 seconds (from
starting pressing the Power- key 3-6).
5. Calibration
5.1 Zero adjustment:
TE
Tel: +49-[0]7433- 9976-174
Fax: +49-[0]7433-9976-285
Internet: www. sauter.eu
Zero adjustment for `F` and `N` should be carried out
separately. The iron base plate is to be used if `F` is
shown on the display. The base plate of aluminium is
to be used if `NF` is shown on the display. .
The sensor 3-1 is to be placed carefully onto the base
plate and the Zero- key is to be pressed without lifting
the sensor. `0` appears on the display.
Attention: The calibration is invalid if the sensor is
not directly placed on the base plate or another un coated material.
5.2 An appropriate calibration foil is to be selected
according to the measurement range.
5.3 The selected standard foil is to be placed onto the
base plate or the uncoated material.
5.4 The sensor 3-1 is 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.
5.5 Repeat step 5.4 until the accuracy is achieved.
6. Battery replacement
6.1 If the battery symbol ``+/-`` appears on the display, the
batteries should be replaced.
6.2 The battery cover 3-8 is to be removed and the
batteries are to be taken off.
6.3 The batteries (4x1.5V AAA/UM-4) are to be installed
correctly into the case.
6.4 If the instrument is not to be used for an extended
period, batteries are to be extracted.
7. Correct handling of 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 recommendable to effect several test measurements
before the first use of the instrument. This way, further
measurement errors can be avoided.
