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.
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:
