play. The instrument enters the auto mode which can automatically recognize the
base plate or base itself.
b) The sensor 3-1 has to be placed onto a coating layer to be measured. The reading
on the display is the thickness of the coating layer.
c) For the next measurement the sensor 3-1 has to be lifted for more than 1cm, “0”
appears again and step b) has to be repeated.
d) In case of inaccuracies to the measurement result, it is recommended to adjust
(calibrate) the instrument before measuring, as described in chapter 5.
e) The instrument can be switched off by pressing the Power- on/ Power- off key 3-3.
The power will switch off 80 seconds after the last key operation.
f) 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).
g) To change the measuring mode from `single` to `continuous or vice visa, the Zero/
Power- key 3-3 has 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. To
change back to single mode, just press the Power-key again for 8 seconds. If
((•))
has disappeared on the display, you are back in single measurement mode.
5 Adjustment
a) Zero adjustment:
Zero adjustment for `Fe` (=F) and `NFe` (=NF) should be carried out separately.
The iron base plate has to be used if `Fe` is shown on the display. The base plate of
aluminium has to be used if `NFe` is shown on the display.
The sensor 3-1 has to be placed carefully onto the base plate and the Zero-/ Power
key 3-3 has to be pressed without lifting the sensor. `0` appears on the display.
Attention: The adjustment will be invalid, if the sensor is not directly placed on
the base plate or another uncoated material.
b) An appropriate adjustment foil, according to the measurement range, has to be
selected.
c) The standard adjustment foil has to be put onto the base plate or the uncoated
base material for the outstanding tests.
d) The sensor 3-1 has to be placed in the middle of the standard foil and then be
lifted. The reading on the display is the measured value. The displayed reading can
be corrected by pressing the UP- button A or the DOWN-button B, which are located
in the battery compartment. This has to be done while the sensor is away from the
base plate or the material to be measured.
e) Step d) has to be repeated until the result is correct.
