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 2360 and DIN as well as ASTM and BS. It is suitable for the laboratory and for use in `harsh field` conditions. * 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, nonmagnetic stainless steel etc. * Automatic substrate recognition * Manual or automatically “auto power off” to conserve batteries. * Two measurement modes: - single and continuous * Wide measuring range and high resolution * Date transfer to PC possible

Instruction Manual

3-5 Minus- key 3-6 Power on/ Power off- key (multi functional) 3-7 µm/ mil conversion key (shortcut key) 3-8 Battery compartment/ cover 3-9 S/C- key (single/ continuous) 3-10 Jack for RS-232C interface 3-11 F/ N- key

4. Measuring procedure

4.1 Press the Power- key 3-6 to switch on the instrument. The instrument recognizes the sensor itself by the symbol `Fe` (=F) or ` NFe`(=N) whitch 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 (Offset- Accur function). For doing this the sensor should be away from the measured object or the base plate.

4.3 For the next measurement just lift the sensor 3-1 for more than 1cm and step 4.2 is to be repeated.

4.4 If suspected the accuracy of measurement it is re commended to calibrate the instrument before measuring, as described in part 5.

4.5 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.

4.6 The measurement unit can be indicated with `µm` or `mil`. To convert: by pressing the conversion key 3-7 or by pressing the Power- key 3-6 and without releasing it till `UNIT` appears on the display. Then the Zero- key 3-3 is to be pressed. All in all this operation lasts about 7 seconds.

4.7 To change the measuring mode from `single` to `continuous` or the other way round, the Power- key 3-6 is to be pressed and not re leased 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: The sensor 3-1 is to be placed carefully onto the appropriate base plate or another uncoated base material. The Zero- key 3-3 is to be pressed without lifting the sensor. `0` appears on the display.

Fax: +49-[0]7433-9976-285 Internet: www. sauter.eu

Attention: The calibration is invalid, if the sensor is

not directly placed on the base plate or another uncoated 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 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. Trouble shooting

7.1 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.

7.2 Sensors will eventually wear off. Life of the sensor will depend on the number of measurements taken and how abrasive the coating is.

8. Restore factory settings

8.1 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.

8.2 How to restore: Factory settings are easily to be restored. The procedure is as follows:
