1. INTRODUCTION
With FERRITE-CHECK 110 you can easily and quickly measure the errite content in
steels according to ISO 8249.
ISO 8249 particularly ocuses on austenitic steel and duplex steel ( erritic / austenit-
ic) to be evaluated or welding operations: i the errite content is too low, the weld
metal becomes susceptible to cracking; i the errite content is too high, toughness
and corrosion resistance are reduced. For duplex steels, a lack o errite at the weld
causes a reduction in strength.
The determined errite number is a description o the errite content in a weld metal,
which is determined in a standardized procedure. Instead o the errite number (FN),
the errite content (Fe%) can also be determined. The conversion is about 70% o
the FN value. The errite content determined as Fe% does not necessarily corre-
spond to the actual or absolute errite content. There ore, the errite number is more
commonly used.
Uneven or round sur aces (as on rods), as well as contamination o the sur ace, can
lead to incorrect or inaccurate measured values
FERRITE-CHECK 110 is pre-calibrated, but is supplied with three calibration
standards or easy recalibration. The instrument is calibrated be ore delivery using
calibration standards provided by the National Institute o Standards and Technology
(NIST).
The "FN140" standard placed on the le t in the case has a bright steel sur ace and is
to be used or zero calibration (base calibration) during two-point calibration.
In the center and right o the case are two standards covered with copper oil. They
represent di erent errite numbers (approx. 6, approx. 17). The exact value is
written on the respective standard.
The standard with the lower FN number is also used or the two-point calibration, the
second step, called FN calibration.
Alternatively, you can also calibrate with the third standard, especially i you
regularly have higher errite values on your workpieces. This increases the accuracy
o these measurements.

2. QUICK START GUIDE
The instrument is factory calibrated and ready for immediate
use.
Switch on: Press the red button or a long time, the display shows
Ready
Measure: Place the device with measuring probe on the object to
be measured and wait until a signal tone con irms the
measurement.
Switch off: Press red key until display goes dark
3. OPERATING THE DEVICE
WITH THE RED BUTTON
Press the key brie ly to scroll through the menu unctions, press and hold the key
(with signal tone) to activate the desired menu unction.
The menu unctions can only be called up i the measuring probe is not placed on an
object.
At the end o each submenu there is a display Back that allows you to exit the
submenu.
In the delivery state, English is preselected as the language.

4. MEASUREMENT DISPLAY
The standard display shows the FN value o a single measurement
By changing the measuring unit (Setup / Unit), the measurement can be displayed
in Fe%.
When the measurement type is changed to the average value measurement (Mode /
Average measurement), the current single value and the average value o the
measurement series are displayed, since the last time the probe was placed on the
object.
You can also use the average measurement with unit Fe%.

5. MENU FUNCTIONS
a. O
FF
By pressing the key or a long time (long signal tone), the device is switched o
manually.
I you keep the key pressed or more than 3 seconds a ter switching o , the
irmware version is also displayed.
The automatic turno time is 2 minutes in the delivery state and can be changed un-
der the menu item Setup.
b. C
ALIBRATE
You can recalibrate the instrument at any time on the supplied calibration standards
with a two-point calibration.

ALIBRATION
The base calibration is called zero calibration, although its result is not FN 0, but FN
140. FN 140 corresponds to 100% Fe and is the value o ull iron or saturated errite
material.
In the o -hook state, select in the menu 0 - Base Calibration, then place the
instrument with the measuring probe on the FN140 calibration standard. Now wait
until the FN140 value is displayed and con irmed by a signal tone, and then li t the
instrument again.

FN
C
ALIBRATION
The FN calibration is the second calibration point or the accurate calibration o the
device (two-point calibration).
The FN calibration is normally per ormed on the calibration standard with the lower
speci ied FN value.
Select FN Calibration in the o -hook state, then place the instrument with the
measuring probe on the calibration standard and wait until the FN value is displayed
and con irmed by a signal tone.
I high errite contents are measured regularly, it makes sense to use the calibration
standard with the higher FN value.
