 Operation

a) Inserting the batteries

• Unscrew the screw from the battery compartment cover (11) with the help of the small folding handle; you can do this by hand or with the aid of a suitable screwdriver (cross head), turning anti-clockwise. Remove the battery compartment cover (11).
•  Insert two AA batteries (two batteries are included for setup) with correct polarity into the battery compartment (observe plus/+ and minus/-). The polarity is indicated in the battery compartment.
• Then, close the battery compartment again with the battery compartment cover and screw the screw in a clockwise direction.

b) Low battery indicator

• The battery level of the measuring device is indicated by the battery level indicator. If the battery status symbol is displayed, it is time to replace the batteries.
  c) Replacing the batteries

• Replace the batteries if the battery level is low or if the LC display (2) no longer displays anything or the display is unclear.

• Remove the used batteries before inserting the new batteries.

• Proceed as outlined in section ‘a) Inserting the batteries.
  d) Attaching the carrying strap
  Attach the enclosed carrying strap to the lifting eyelet (9) to carry the layer thickness measuring device safely.

a) Switching the measuring device on/off
Prior to each use, the measuring device must be checked for correct the zero point and accuracy. Test and calibration discs are enclosed for this purpose. The test and calibration discs may be stored in the inside pockets of the holster. To switch on/off, proceed as follows:

•  Keep the measuring device away from metallic objects and magnetic fields.
• Press and hold the power button (3) until the LC display (2) lights up. Initialisation progress is displayed as a percentage. A signal tone sounds when the acoustic messages are active. After initialisation, normal measuring mode is automatically switched on.
• To switch the measuring device off, press and hold the power button (3) until the LC display goes off. A signal tone sounds when the acoustic messages are active.

b) Performing a function test
After switching on, perform a function test before each measurement series.
1 Testing the zero point

• Remove the protective cap from the sensor (8).
• With the measuring device switched on, place the sensor (8) on one of the two metal plates, ensuring that it is flat. ‘0’ must appear on the display. Repeat this measurement with the second metal plate. ‘0’ must appear on the display here too. If this is not the case, the measuring device must be calibrated (see section ‘Calibrating the measuring device’).
• Depending on the carrier material, ‘NFe’ will appear for non-magnetic metals and ‘Fe’ for magnetic metals for the measured value.

2 Checking measurement accuracy

• Check the measurement accuracy by using the plastic films supplied in the layer thickness set.
• Carry out the functional test as outlined above but place a layer thickness standard (plastic film) in between. The material thickness is printed on the storage bags for the plastic foils in µm. This value must be displayed in the tolerance limits range also specified on the LC display (2). If this is not the case, the measuring device must be calibrated (see section ‘Calibrating the measuring device’).
• Place the layer thickness standards back into the correct pockets. If you confuse them, you must re-measure with a micrometre screw before each calibration.

Taking measurements

a) Single measurement

• Switch the measuring device on and remove the protective cap from the sensor (8).

• Carry out a functional test.

• To do this, place the sensor (8) on the metal surface to be measured, ensuring that it is flat. Ensure that the sensor is not tilted or moved.

• Do not apply too much force to the surface. This may lead to faulty measurements and to damage to the surface.

• Wait until the measured value is displayed. Place the measuring device in another location to carry out additional single measurements periodically.

• Determine approx. three to five measuring points are distributed roughly evenly over the surface of the measured object.

• Take five measurements per measuring point and calculate the average value of these measurements.
  This value now counts as the reference value for the layer thickness at the given measuring point.

•  Repeat this procedure for all other measuring points. You may also choose a higher measuring point density to achieve even better statistical accuracy.

• The average value of the measurements of all measuring points then corresponds to the normal layer thickness on the measured object.
  → If a measured value is above 1250 µm but still below 1500 µm, ‘OL’ appears on the LC display (2). This means that the measured value is outside the measurement range. With measured values of over 1500 µm, the measuring device will cease to respond..

• Replace the protective cap on the sensor (8) after finishing the measurement.
  b) Continuous measurement (continuous measurement series)

• Set the continuous measurement as outlined in section ‘j) Setting continuous measurement’.

• When the continuous measurement is set, the measuring device automatically measures the values of the layer thickness at intervals when the sensor (8) is placed on a measured surface. A measurement tone sounds each time a new measurement is taken. Measurement is repeated until the measuring device is lifted away from the measured object or the power supply is interrupted/switched off.

c) Data storage
The measuring device enables the storage of measured values in up to 500 groups, which can be read out later with the help of the PC software. The data logger function is always active and records each measurement chronologically. The storage space is sufficient for a maximum of 500 measured value groups.

Measurement method

a) Teach-in mode
This measuring mode is used for the quick measurement of surface coatings in industrial environments, e.g. coatings on automobiles or other mass-produced products.
The measured results are evaluated as good or reject.

  – Multi-point average measurement

• Confirm your selection with the confirmation button (4) to switch to the selected measuring mode or press the Clear button (5) to leave the menu without switching.
  2 Setting and taking single-point measurements in teach-in mode
  With single-point measurement, a measured value is taken and immediately evaluated as a single value as good or reject. To do this, set the required value (100 µm in the example) for the layer thickness and the permissible upwards and downwards tolerance (10 µm in the example).

2 Setting and taking single point measurements in teach-in mode
With single-point measurement, a measured value is taken and immediately evaluated as a single value as good or reject. To do this, set the required value (100 µm in the example) for the layer thickness and the permissible upwards and downwards tolerance (10 µm in the example).

• Press the up button (7) and down button (6) to select the desired layer thickness value. Confirm your selection with the confirmation button (4).
• Press the up button (7) and the down button (6) to select the desired tolerance value. Confirm your selection with the confirmation button (4) to start measuring with single-point measurement.
• Measure a point on the measured object. The LC display (2) shows ‘PASS’ or ‘FAIL’ according to the setting. If ‘PASS’ is displayed, the tested workpiece is good. If
  ‘FAIL’ is displayed, the workpiece is a reject or needs to be reworked.

•  Press the button (5) to return to single-point measurement and continue measuring.
•  Press and hold the button (5) to exit the single-point measurement and stop measuring.

1 Setting and taking the average measurement
Average measurement takes three measured values at three nearby points and averages them. This average value is then evaluated as good or reject. Set the required value (100 µm in the example) for the layer thickness and the permissible upwards and downwards tolerance (10 µm in the example).

• Press the up button (7) and down button (6) to select the desired layer thickness value. Confirm your selection with the confirmation button (4).
•  Press the up button (7) and the down button (6) to select the desired tolerance value. Confirm your selection with the confirmation button (4) to start measuring with average measurement.
• Measure three times in a limited area on the measured object. The measuring device determines the average of the three consecutive measurements as a measured value for area A.
• Measure three times in a limited area on the measured object again. The measuring device determines the average of the next three consecutive measurements as a measured value for area B.
• Repeat this method three more times for points C, D and E. The measured average value is taken as a measured value for the measured surface.
• After the measurement series has been completed, the average value of the series, as well as ‘PASS’ or ‘FAIL’, are displayed on the LC display (2). If ‘PASS’ is displayed, the tested workpiece is good. If ‘FAIL’ is displayed, the workpiece is a reject or needs to be reworked.Press the Clear button (5) to return to the average measurement and continue measuring. Then, repeat the measurement procedure outlined above for all five measured surfaces.
• Press and hold the Clear button (5) to exit the average measurement and stop measuring.
