Annotation: It is strongly recommended to calibrate
the new instrument before the first use, as
described in paragraph 9. By doing this it
will be achieved a much better measure ment result right from the start.
1. Features
* This instrument meets the standards of both, ISO 2178
and ISO 2361, and DIN as well as ASTM und 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. Those layers are to be found on magnetic
base materials like iron, steel, nickel et c.
* The N mode measures the thickness of nonmagnetic
coatings, e.g. anodizing, varnish, paint, enamel, plastic
coatings, powder etc. These layers are located on non magnetic metals e.g. aluminium, brass, non magnetic
stainless steel etc.
* Automatically substrate recognition
* Manually or automatically “auto power off” to conserve
batteries.
* Two measurement modes: - single and continuous
* Wide measuring range and high resolution
* Metric/ imperial conversion
* Digital backlight display enables exact reading with no
guessing or errors
* Can communicate with PC for statistics and printing by
the optional cable.
* Can store up to 99 measurements
* Statistics available

4. Measuring procedure
At model TG, the F-/NF- sensor (aut omat ically recogniti on)
has to be plugged in, to get into the F- or NF- mode.
4.1 The power key 3-3 has to be pressed to switch on the
instrument. `0` appears on the display 3-2.
With the Auto- Mode, the instrument recognizes the
mode itself by the symbol `Fe` (= F) or `NFe`(= N)
which is indicated on the display.
4.2 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
For doing this the sensor should be away from the
measured object or the base plate.
4.3 For the next measurement the sensor 3-1 has to be
lifted for more than 1cm and step 4.2 is 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 change the measurement unit from „µm“ to “mil” or
vice verse, the Power-key just 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.
4.5 To change the measuring mode from `single` to
`continuous` or vice verse, the Power-key 3-3 has to
be pressed and not released until `SC` appears on
the display. Then the Zero- key 3-3 has to be pressed.
The symbol “STATS” represents the continuous
mode and `S` represents the single mode.
5. Statistics
This instrument calculates and displays a statistical
analysis of readings while the measurements are taken.
The statistics available are:
• Last value
• Mean value
• Highest reading marked by Max
• Lowest reading marked by Min
• Number of readings taken
To clear the statistical data before starting a new set of
data, the Zero-key just has to be pressed and releas ed. In
measurement mode, which is marked by SV , the last value
can be deleted by pressing the DEL-key. Restatistics is
calculated and displayed itself.
