Annotation: It is strongly recommended to calibrate the new instrument before the first use, as described in paragraph 5. 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, 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.
»Automatic substrate recognition.
»Manual or automatically auto power off to conserve batteries
»Two measurement modes:- single and continuous
»Date transfer to PC possible

4. Measuring procedure
4.1 The Power- on/Power-off key 3-3 is to be pressed 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. The instrument enters the auto mode which can automatically recognize the base plate.
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.
4.3 For the next measurement the sensor 3-1 is to be lifted for more than 1cm and step 4.2 is to be repeated.
4.4 In case of inaccuracies to the measurement result it is recommended to calibrate the instrument before
measuring as described in part 5.
4.5 The instrument can be switched off by pressing the Power- on/ Power- off key 3-3. The power will switch itself off 50 seconds after the last operation.
4.6 The measurement unit can be indicated with `µm` or `mil`. To convert: The Zero/ Power- on/ off key 3-3 has to be pressed and not to be released until `UNIT` appears on the display. The measurement unit changes by releasing. All in all this operation lasts about 6 seconds (from starting pressing the Zero-/ Power-on/ off key).
4.7 To change the measuring mode from `single` to `con­ tinuous or vice visa, the Zero/ Power- key 3-3 is to be pressed and not released until `SC` appears on the display. The measuring mode changes into the other one when the key is released. This lasts about 8 seconds. The symbol ((•)) on the display
indicates the continuous mode.
5. Calibration
5.1 Zero adjustment: Zero adjustment for `Fe` (=F) and `NFe` (=NF) should be carried out separately. The iron base plate is to be used if `Fe` is shown on the display. The base plate of aluminium is to be used if `NFe` is shown on the display. The sensor 3-1 is to be placed carefully onto the base plate and the Zero-/ Power 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.
6. Battery replacement
6.1 If the battery symbol ``+/-`` appears on the display, the batteries should be replaced.
6.2 The battery cover 3-4 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. Calibration foils
As accessory there is included a foil set of different foils and ranges, which is to be seen below.
Range (µm)

0-500 X X X X
0­1000 0­2000
8. Trouble shooting
8.1 The instrument should always be calibrated on the uncoated base material to be measured instead of the base plate included in the delivery. Then the accuracy is more precise.
8.2 Sensors will eventually wear off. Life of the sensor will depend on the number of measurements taken and how abrasive the coating is.
