Set measurement methods: Auto FN identification, Ferrous and Non-Ferrous mode
When using FN combination probes, the display shows “Auto FN”. This indicates automatic base
material recognition after positioning the probe and activation of the appropriate measuring
method.
In some cases, e. g. when measuring paint on zinc on steel, it may be useful to select the
measuring method manually, e. g. selecting Ferrous when measuring the total coating thickness,
and Non-Ferrous when measuring the paint thickness on zinc.
Procedure:
1. Press Arrow Down key three times until “Measuring mode” appears on the display
2. Press OK key; “Autom. Detection FN, F, N” appears on the display
3. Press OK key; “Automatic identification (FN)” appears on the display
4. Use the arrow keys to select the desired method: “Automatic identification (FN)”, “Ferrous (F)”
or “Non-Ferrous (N)”
5. Press OK key to confirm your choice. The chosen mode is displayed, e. g. “Measuring mode FN
selected”, followed by the start screen with the four dashes – – – –

Limit values
This section describes how to set the limit values. To monitor your readings, you can set an upper
and a lower limit value. This setting is useful:
- during the measurement
- for the evaluation of readings later on when displaying the single values
- when analysing the readings with the PC.
If the reading is outside of the limit values, you will hear a beep sound, the reading is displayed in
red
and an indicator LIMIT ↑ or LIMIT ↓ at the top of the display shows whether the reading fell
below or exceeded the limit values. Readings within the limit values are displayed in
green
.
Setting the limit values
Procedure:
1. Press Arrow Down key three times until “Measuring mode” appears on the display
2. Press OK key; “Autom. Detection FN, F, N” appears on the display
3. Press Arrow Down key; “Limits” appears on the display
4. Press OK key; “Limits setting” appears on the display
5. Press OK key; “Set lower limit” appears on the display, along with a number as a suggestion
for the lower limit value
6. Use the arrow keys to adjust the lower limit value; by pressing and holding these keys, the set
value increases or decreases more quickly
7. Press OK key; “Set upper limit” appears on the display, along with a number as a suggestion
for the upper limit value; the upper limit value must be at least 10 µm higher than the lower
limit value
8. Use the arrow keys to adjust the upper limit value; by pressing and holding these keys, the
set value increases or decreases more quickly
9. Press OK key; “Limits have been set” appears on the display for a short time, followed by the
start screen with the four dashes – – – –
The limit values are set for the measuring method (Ferr, Non-Ferr) which was activated last. When
the base material changes, the limit values have to be set again, if desired.
When transferring the readings to a PC, a “<” sign in front of the thickness value indicates a
reading below the lower limit value; a “>” sign indicates a reading above the upper limit value.
