Operating the Gauge
To turn on the gauge, simply place the probe on the surface you wish to test; or turn on the
gauge manually by pressing one of the four buttons on the device. If the probe is not used for
more than 30 seconds, the gauge automatically shuts down. When using a radio-controlled
probe, the gauge has to be turned on again if several minutes passed without taking a read-
ing.
When placing the probe take care to seat the bearing ring plainly on the measuring surface.
On curved surfaces align the V-grooves as parallel to the axis of the curvature as possible,
thus ensuring a vertical position of the measuring head on the measuring surface.
We suggest holding the gauge on the recessed grips during the measuring process to en-
sure the highest accuracy.
Incorrect placing will be indicated as an “Error” message on the gauges display and meas-
urements outside the measuring range as an “Infi” (=infinite) message.
Please do not carry out any measurements on magnetized parts. Magnetic fields can influ-
ence the readings, just as electro-magnetic radiation can influence the NFe-readings.

Stationary Application
For stationary use
– e.g. in a measuring stand – you can take the reading by pressing a but-
ton. To do this, set the function of the
▲ Button in the “Setup” menu to “Measure” (see
§ 8.5.7).
To take a reading by pressing a button, you do not have to place
the probe on a surface nor
is it necessary to press the measuring head. Within the measuring range of the probe,
measurements like e.g. distance measurements are possible that way.

Setting the Zero Reference
When using the gauge for the first time, after changing the batteries, with varying applica-
tions or from time to time a zero point adjustment is necessary. First select the measuring
mode (the substrate on which you want to take a measurement) either via menu (see § 7) or
using the automated substrate selection while in the Fe/NFe-mode. A zero point adjustment
on wrong substance however leads to irreproducible results. Press the
▲
button
and then ei-
ther place the probe on one of the reference plates included in the gauges case or use an
adequate uncoated Fe- or NFe substrate. The display will show a control number; lift the
gauge or the probe at least 5 cm (2”) from the surface. The display will show a second con-
trol number for a short time, then the value 0.0µm appears and the zero point adjustment is
completed.
The control numbers shown are of no relevance to the user. You can ignore them.
The radio controlled probe acknowledges the recording of the zero and infi values while in
wireless mode with a flashing of the blue light inside the probe for about half a second.
NOTE: While the zero reference can usually also be set by placing the probe first and then
pressing the
▲
button, this does not apply when using the radio controlled probe in wireless
mode.
Alternativ
ely use the menu items “Zero” and “Infi” within the “Calibration” menu to set the ze-
ro reference. Select the corresponding menu items to activate the recording of the zero and
infinity values. This is especially useful if you defined the
▲
button
within the gauges setup
for taking a measurement (see § 8.5.7).
Regarding zero point adjustment on rough surfaces refer to § 8.1.2.
