Measuring Mode
The gauge offers different methods for selecting a measuring mode.
Set the measuring method either by following the standard menu sequence as described in
§ 8.2.1 or by using the ◄ button for direct access while the gauge is in standard display
mode.
Fe or NFe mode:
Fe/NFe mode:
Combined mode:

Menu
For your convenience, find a diagram of the menu structure showing all possible menu op-
tions on the first two pages of this instruction manual. Depending on the version of your
gauge only a part of the menu items shown might be available for you. This however does
not change the proceedings when selecting available menu items.
Functions of the gauges buttons while in menu mode:
►
activate the menu, proceed to the next menu level, call the menu item selected.
◄
back to the last menu, cancel a function
▲, ▼ scroll through a list within a menu level using these buttons
A dark background indicates (highlights) the selected menu item.
●
This symbol marks active menu items
In memory mode (see § 8.3) and with several memory batches defined, use the▼ button to
activate the menu.
You can always leave the menu mode by pressing in the measuring head. The gauge then
immediately returns to display mode.
8.1
Calibration
The probe is delivered with a factory calibration showing correct readings for most applica-
tions. This calibration is stored in the probe and cannot be changed by the user.
With this gauge, it is also possible to set custom-designed calibrations. These are necessary
under certain measurement circumstances: when the readings are not within the given toler-
ance or when you want a more accurate reading within the expected range of the coating
thickness.
Depending on your gauges version up to 100 different user-specific calibrations can be set,
saved and each named individually.
Instruction Manual QNix
For applications with a clearly defined substrate, the Fe or NFe mode
can be set fix.
For applications with constantly varying steel or non-iron substrates,
best use the Fe/NFe mode.
If for example the substrate changes from steel to non-iron, simply
place the probe on the new (NFe) substrate once. The message „No
Fe Substrate – Repeat" will appear. When placing the probe for a sec-
ond time, it automatically repeats the measurement in the NFe mode.
Follow the same procedure if the substrate changes from non-iron to
steel.
The next time the gauge is turned on, it starts operating in the measur-
ing mode last used.
Use this mode when for example an object made from steel has been
hot zinc dipped and then painted. The gauge then displays the thick-
ness of the zinc coating and the paint as two separate values.
For the use of the combined mode, the metallic coating of the magnet-
ic substrate must have a minimum thickness of 50 µm.
