of the display, the wireless symbol is indicated together with a small “P” for probe. You can
take measurements with the radio controlled probe the same way you do with the usual
probes. Each reading that is correctly transmitted to the gauge is indicated with a short flash-
ing of the blue probe light. That way you can observe if the probe is still inside radio range.
As the radio-controlled probe uses a special radio mode to ensure maximum operating safe-
ty, observe the following during radio communication between gauge and probe:
With disconnected probe, the wireless mode is switched to the probe and any communica-
tion between gauge and PC is no longer possible. However, readings are still transmitted to
the PC as online-measurements. To readout the memory and to change the gauges setting
via PC the probe has to be reconnected to the gauge.
Deactivating the wireless mode via the gauges menu has no effect on the radio-controlled
probe. An activation of the wireless mode using the gauge however leads to a disconnection
of the communication with the radio-controlled probe.
10 Troubleshooting
10.1 Incorrect or dubious readings
If the gauge shows incorrect or dubious readings, please check:

Does the display indicate the correct substrate? If you are not sure whether your sub-
strate is Fe or NFe, test it with a magnet; if the substrate is attracted by the magnet,
choose the an Fe probe or the Fe measuring mode of a dual probe, otherwise choose
the NFe mode or a NFe probe.

Is the Zero Reference correctly set? You achieve the best results when you zero the
probe on an uncoated piece of the substrate whose coating you want to measure. If
an uncoated piece is unobtainable you can use the standard plates that are supplied
with your gauge. Refer to §6 for further details. Please note that it is the probe that
you zero, not the gauge. The results of the zeroing are stored in the probe. Thus if
you switch the probe, you might have to repeat the setting of the zero reference.

Is the substrate you want to measure suitable for a standard calibration? Certain al-
loys that contain iron, in particular some kinds of stainless steel, require special con-
sideration. You should use a custom calibration ( see §8.1.1) in these cases.
10.2 Automatic selection of the substrate does not work
This is caused by an incorrect setting of the zero references of the probe. To recover from
this, follow these steps:
1) Set the gauge to Fe mode (select Fe from the substrate menu, see §7).
2) Set the zero reference on an uncoated sample of Fe material or on the standard Fe
plate that was supplied with your gauge.
3) Set the gauge to NFe mode (select NFe from the substrate menu).
4) Set the zero reference on an uncoated sample of NFe material or on the standard
NFe plate that was supplied with your gauge.
10.3 My gauge does not provide all the described features
There are 2 possible reasons for that:
You have the Basic version and the feature you are looking for is only available in the Premi-
um version. Check the menu overview on page 2 and 3.
The feature you are looking for was introduced after you purchased your gauge. In that case
an update of the gauge firmware might help. Please contact your dealer for details.
If you want to know the version of the firmware in your gauge, select “Info” from the setup
menu (see §8.5.3). The gauge will display a popup window containing the serial number of
the gauge and a 7 digit string indication hardware and software version of the gauge. The
