Be sure the measuring head is lying flat. If the reading showing on the zero plate or its substrate is outside the measuring
accuracy, you should carry out the zero setting again as follows.
Place the probe on the zero plate, i.e. the substrate, and briefly press the button on the instrument. A control figure will
appear in the display and an audible signal will be given. Then lift the instrument at least 10 cm. A control figure will again
appear in the display and an audible signal will be given. The zero reset is now complete.
When performing multiple measurements on the same spot, you will not necessarily receive the same 0 µm/mil, as surface
roughness or dirt can cause fluctuations in the measurements etc.
Handling
Place the measuring head flat on the place to be measured. Be sure the ring­like contact surface around the measuring
probe is lying flush on the measuring spot. Hold the device by the recessed grips near the measuring head to avoid
tipping. The measured value will now appear in the display along with a signal tone. Along with the measured value, you
will also be provided with information on which probe, i.e. Fe or non­Fe, the instrument used to make the measurement. This
is particularly important when using the dual­probe.
When carrying out the zero setting on non­metallic substrate or when the device is used incorrectly, „Zero Reference Error"
will be displayed. Measurements outside the range of the probe will be accompanied by the message „INFI" (= infinite).
The instrument automatically switches on when the probe is put in place, and if it is not used, switches off again after app.
30 seconds. When measuring bars, rods, pipes etc., the V­shaped groove in the measuring head can be useful.
Setting Measuring Mode and Unit (µm or mil)
Pressing the operating button with the device switched on but not laid on will display the possible measuring modes and
‚UNIT'. The respectively current measuring mode is shown marked in the display. Pressing the operating button switches
over to the respective next measuring mode. This is activated when the button is then not pressed for approx.
2 seconds. If ‚UNIT' is marked and then no further action is taken, a menu with ‚µm' and ‚mil' is opened in which the set
measuring unit is marked. You can select the respective other unit by pressing the button.
Measurements with Dual Probe
The device offers various options for selecting the measuring mode. The measuring mode can be set by pressing the
operating button with the device switched on, as described above.
Fe or Non­Fe mode:
For applications in which the substrate is clearly specified, the Fe or non­Fe mode can be permanently set. The measuring
mode currently in use is shown on the left­hand edge of the display.
Fe/Non­Fe mode:
When continually changing between steel and non­iron substrates, the Fe/Non­Fe mode can be activated. In this mode,
which is indicated in the display with a symbol with two round arrows, the device is in the semi­automatic mode. In this
case, a message appears when the substrate is changed which points out the change and requests that the user lift off the
probe and then lay it on the substrate again for repeat measurement.
Please note that it is possible with the non­Fe measuring method to conduct a measurement on a ferromagnetic substrate
(e.g. iron or steel). However, the indicated value is not correct due to the magnetic properties of the substrate. Therefore,
when using the non­Fe measuring method, make sure the substrate is not ferromagnetic, e.g. with an additional checking
measurement with the Fe measuring method.
When using the non­Fe measuring method, it is possible when conducting a measurement on the Fe zero plate provided
that either INFI or a numeric value will be displayed. This cannot be influenced and does not represent poor quality.
Should you feel that the measuring results are implausible, despite a zero calibration (e.g. no zero results occur on the
plates provided), deactivate the automatic mode changeover and conduct a zero calibration on the plates provided in
both modes.
