Krautkrämer MIC 10 Issue 08, 08/01 1-1
1.1 Krautkrämer MIC 10
The hardness tester MIC 10 from Krautkrämer is
handy, easy to operate and can carry out tests quickly
without any difficulty.
It mainly is suitable
• for hardness measurement of low and non-alloyed
steels,
• for hardness measurement of high-alloyed steels,
• for hardness measurement of nonferrous metals.
The MIC 10 can be delivered in two versions:
• the basic version "B"
• the Data Logger version "DL"
As opposed to the B version, the DL version has additional functions for data storage:
You can store readings in the instrument in order to
have them printed or, using special software, transfer
them to a PC. With the auxiliary Memory Card you
have access to almost unlimited storage possibilities
and flexible data processing.
Introduction Krautkrämer MIC 10
1-2 Issue 08, 08/01 Krautkrämer MIC 10
Compared to customary Vickers low-load hardness
testers, the MICRODUR series from Krautkrämer
does not evaluate with a microscope but uses the UCI
method electronically. The measured hardness is instantly displayed digitally and high reproducibility of
the test results is achieved. The indent in the surface
of the material is microscopic.
We are constantly working on further instrument development. Therefore we hope that you appreciate our
right to carry out technical changes.
Your nearest Krautkrämer Sales Center is ready to
help you concerning service questions. In addition to
this, you can contact our Customer Service or Service

1.4 Conditions for hardness testing
You will find all the essential instructions for operation
of the MIC 10. In addition to this there are a series of
factors which affect the test results. Due to the fact
that a description of these factors would extend beyond the scope of this manual, the three most important conditions are as follows:
• training of the operator
• knowledge of the special technical requirements
and limits
• selection of the suitable test setup
Training of the operator
For reliable application of a hardness tester suitable
training in the field of material testing is required.
Suitable training means, for example, suitable knowledge about:
• hardness testing on metallic materials.
• effects of material properties, especially the struc-
ture, on the hardness test and the selection of a suitable hardness testing setup connected with it.
• the problems of comparability of different hard-
nesses such Vickers, Rockwell and Brinell. Also
refer to the information given in the Appendix.
• the effects of surface treatment on the hardness
value.
• the effect of the test load, and the size of the indent
connected with it, on the determined hardness
value.
Please read also the instructions in chapter 1.5.
) Attention:
Insufficient knowledge of the above mentioned
fields can cause wrong test results and could
have unforseeable consequences.
Introduction Conditions for hardness testing
1-6 Issue 08, 08/01 Krautkrämer MIC 10
Test requirements
Every hardness test has certain requirements. The
most important are:
• determination of the test scope
• selection of a suitable testing technique
• consideration of the material properties
• Determination of the evaluation limits
Selection of a suitable test setup
It is the task of the person responsible for the test to inform the operator about the test requirements. In addition to this, a clear and complete interpretation of the
corresponding test specifications is urgently required.
Information about the test method and test specifications are, amongst others, obtainable from different institutes, industrial companies and authorities.
1.5 Important notes on MIC 10
New display
The MIC 10 display has changed as from instrument
serial number 1001. Please take into account when
retrofitting new software to an instrument having a
smaller serial number. This change does not affect the
operation in any way.
The average is now indicated with before the reading; the indication S for the single value is dropped (no
indication=single value). The indication s (seconds) for
the dwell time is likewise dropped. The indication for
the probe contact and the hardness scale N/mm

Important notes on MIC 10 Introduction
Krautkrämer MIC 10 Issue 08, 08/01 1-7
In the following you will find a summary of the most important technical test requirements that you always
have to comply with to ensure correct measurements.
Test material
The test loads (probes) must match the surface quality
of the material:
• smooth, homogeneous surfaces require low test
loads
• rougher, coarse-grained surfaces require as high
test loads as possible.
The surfaces must always be free of any impurities
(oil, dust, etc.) and rust.
The surfaces roughness should not exceed approx.
30 % of the penetration depth.
Thin metal sheets must have a thickness corresponding to the tenfold indentation depth of the Vickers diamond.
For more details, please also read Chapter 12.3 and
especially the tables on page 12-5.
UCI method
The UCi method is a comparative method (contribution of the Young’s modulus to the measurement) with
a very high reproducibility of the measurements. The
UCI method does not replace the classical testing according to Vickers, but it forms a quick and reliable
complement to it.
The direct comparison with the results from the standardized Vickers measurement according to the material samples is therefore imperative for the
evaluation of the measurement accuracy of the UCI
method. This means:
) Attention:
It is absolutely necessary that you calibrate your
MIC 10 to the material under test.
For this purpose, the calibration only has to be carried
out once since you can easily store and recall or set a
calibration.
The calibration for low-alloy or unalloyed steel is already preset in the instrument. Check it from time to
time (refer to Chapter 9.1 Check function)
For more details on the UCI method, please also read
Chapter 12.1.
Introduction Important notes on MIC 10
1-8 Issue 08, 08/01 Krautkrämer MIC 10
Conversion of hardness values
The conversion of hardness values into other hardness scales is only possible with certain restrictions.
You should only carry out conversions if
• the specified test method cannot be applied (e.g. be-
cause there is no suitable test instrument)
• it is not possible to take the required samples for
the specified test method.
Please read also Chapter 12.2 for this.
) Attention:
Wrong calibration and unacceptable or illegal conversions can cause grave errors in the interpretation of measurement result.
Protection against moisture
) Attention:
Only use the MIC 10 DL (Data Logger version with
board slot) in a dry environment and only clean it with
a dry cloth.

3Preparations for operation
Krautkrämer MIC 10 Issue 08, 08/01 3-1
In order to prepare the MIC 10 for operation you must
carry out the following:
• check the battery supply
• connect the probe
3.1 Battery supply
The MIC 10 is driven by batteries or accumulators. For
this you need two 1.5 V Mignon cells (DIN 40 766):
• dry cells (AlMn) or
• rechargeable (Nickel-Cadmium or Nickel-Metalhy-
drid).
We recommend the use of Nickel-Metalhydrid batteries because the operation time is increased by 60%
The use of batteries or accumulators
You can insert batteries (AlMn) or accumulators
(NiCd, NiMH).
– Loosen the screws on the battery compartment (e.g.
with a coin).
– Open the battery compartment.
– Insert the batteries, observing the correct polarity
(this is marked in the battery compartment).
– Screw the cover back onto the battery compartment.

When the battery voltage is too low a symbol will appear on the MIC 10 display:
If this symbol appears, the batteries must be immediately changed. The MIC 10 automatically switches off
if the batteries are too low in order to guarantee reliable measurement.
When measurements are made at remote locations a
spare set of batteries should be present.
Further information with regard to batteries and accumulators can be found in Chapter 8.1.
0 Note:
Used or defective batteries are special refuse and
must be disposed of according to the governing laws!
3.2 Connection of hand-held probes

5.1 Hardness measurement
The following chapter informs you about how hardness measurements are made with the MIC 10 and
how to carry out adjustments.
If you wish to carry out measurements on low-alloy or
unalloyed steels then instrument calibration is not
necessary because the parameters are already preset
into the instrument.
However, you must carry out instrument calibration if
you wish to measure high-alloy steels or materials
such as non-ferrous metals.
The execution of measurements and adjustments
(hardness scale, alarm thresholds) is basically the
same in both cases.
Turning on the instrument and viewing
the software version number
– You turn on the MIC 10 with
M
.
The MIC 10 automatically carries out a system selfcheck. On the display then appears the following indication for about 2 seconds:
In the middle of the display you can see the software
version code of your instrument. The last three digits
of the version number are displayed, e.g.: 01.01.05
(the first digits are hardware identifiers that you do not
need to identify your instrument).
L indicates the Data Logger version as active instrument version. Additionally, you see the hardness
scales on the right and the display symbols at the top
of the display.
0 Note:
If there is a system error then a code number will be
displayed. You will find a breakdown of code numbers
in Chapter 9.2.
Finally, the instrument will give a short signal tone indicating that it is ready for measurement:

Carrying out the measurement
Measurement on low-alloy and unalloyed steels can
be directly made without calibration because the calibration values for these materials are preprogrammed
in the instrument.
The measurement is normally made as a short time
measurement with a fixed programmed measurement
time of 4 ms. Due to this, measurement inaccuracies
caused by unsteady holding of the probe are largely
excluded.
– Make certain that the probe is connected to the in-
strument and that the conical probe attachment is
screwed on.
– Turn the instrument on.
– When the instrument is already turned on, you are
able to carry out the measurement from each function without having to return to the MEASURE-
MENT level.
– Select the required measurement reading display
(single or average value) and the hardness scale
and set, if necessary, the alarm threshold.
– Position the probe tip vertically onto the surface of
the test material. Pay attention to correct probe
handling.
The probe symbol on the display indicates that contact
has been made.
0 Note:
The measurement must be carried out within 3 seconds after the probe has made contact with the test
material. If the 3 seconds is exceeded a error mess-
age will appear on the display. In this case, press
+
in order to delete the message or carry out another
measurement.
– Press the probe down to the limit for about 1 second.
An acoustic signal indicates the end of the measurement.
The measured hardness value is displayed.
In most cases you will carry out a series of measurements (a set) and not single measurements.
– Position the probe to another point on the test ma-
terial and carry out a further measurement.

Measuring other material
If you do not wish to carry out measurements on low
or non-alloyed steels but on high alloyed steels or materials as nonferrous metals, then you must adjust the
MIC 10 to the required material.
For calibration you will need a test piece made of the
same material having a known hardness. You determine the calibration value which you will need with further measurements on this material.
The calibration value is an additional value that makes
a subsequent change of the calibration setting easier.
As the calibration value has no physical relation, it has
no designation either.
Due to the fact that you can directly enter this calibration value you only need to carry out the calibration
once for a certain material.
– Carry out a measurement set of about 5 single
measurements on your test meterial (corresponding
to the above described measurement on low-alloy
steel).
– Press
M
in order to go to the Set level and then se-
lect the function Calibration (Cal):

the above display appears.
The active average value reading of your measurement will be displayed.
This value does not correspond to the known, real
hardness value because you have not calibrated the
instrument.

You must now match the displayed value to the hardness value of your test material.
– With
^8 you can increase or decrease the dis-
played value (refer to Chapter 4, page 4-7, Accelerated Setting).
When the correct value is set, the instrument is calibrated for the material to be measured.
The calibration value is automatically evaluated according to the set hardness value:
– Press

the DL version of the MIC 10 is made easy. All calibration and adjustment parameters can be stored on a
Memory Card and loaded at any later time by inserting
this card (refer to page 5-29).
The calibration which has been changed is indicated

9Function check and troubleshooting
Krautkrämer MIC 10 Issue 08, 08/01 9-1
9.1 Check function
Visual check of the Vickers diamond
Periodically check the Vickers diamond under a microscope.
Make sure that the pyramid-shaped diamond is not
damaged.
Checking the measurement accuracy
All UCI probes are calibrated using hardness reference plates which are certified by the material testing
institute "Materialprüfungsanstalt MPA NRW" for the
corresponding test load (1 kgf, 5 kgf, 10 kgf). Each
hardness reference plate shows natural variations that
have an influence on the measured value deviations
of the corresponding probe from the plate value.
Under well-defined conditions, as is the case with
measurements using the test support MIC 222 on
Krautkrämer hardness plates with acoustic coupling
(thin oil film or ultrasonic couplant ZG between the reference plate and base), a deviation by ± 3,6 % of the
average from 5 measurements from the plate value is
still permissible (for a max. range of 5 % with reference to the average).
Individual deviations from the plate value may occur in
freehand measurements depending on the probe
handling. However, they should not go beyond 5 %
from the plate value for 10 measurements.
You should carefully study the handling of the probe
and train yourself in working with the probe by carrying
out measurements on the hardness reference plates
until you obtain stable readings.
Repeat these reference measurements from time to
time and note down the measured average in order to
check the measurement accuracy of your probe.
Any sudden variations indicate a defective diamond or
maladjustment of the probe.

function which is active during operation.
When system or operating errors occur they will be indicated by a corresponding error code in the display
(e.g. E 2.0).

Error code Cause Remedy
E 1.1 Error in handling the probe during
measurement (contact time greater than 3
seconds)
Repeat the measurement.
Ensure correct probe handling.
Place the probe with the nececcary pressure
carefully onto the material surface.
E 1.2 Measurement cannot be evaluated (e.g. if
used probe is not suitable for test material).
Repeat measurement.
If necessary, use another probe.
E 1.3 The probe was coupled before termination
of a defined measurement time.
Repeat measurement.
Note the symbol in the MIC 10 display.
E 2.0 Error when reading the Memory Card. Remove the Memory Card and reinsert it again.
If the error reoccurs, use another Memory Card.
E 2.1 Memory Card written by the DynaMIC Delete data or use another Memory Card.
E 3.0 Interface is not ready. Check to see if your printer or PC is correctly
connected.
The MIC 10 gives additional text error messages:
OFL / UFL Overflow / Underflow
Out of range when hardness scale is
changed.
Select another hardness scale.
Full Not enough storage capacity for the data
to be stored.
Delete the contents of the Data Logger or
Memory Card (if necessary, after previous
transfer to a PC) or use another Memory Card.

Measurement method UCI method (Ultrasonic Contact Impedance) with Vickers diamond
Test load Handheld probes MIC 201-A (10 N), MIC 205-A (50 N), MIC 2010-A (98 N)
Indentor Diamond pyramid according to Vickers, roof angle 136°
Test materials Metallic materials
Basically, measurements are also possible on glass and ceramics.
Please contact your Krautkrämer service agent.
Measurement tolerances Max 5% tolerance in the Vickers hardness range from 200 HV to 900 HV.
Max ± 3.6% deviation from the average measurement value to the value of
the hardness reference plates.
These deviations are determined from 5 single measurements using the test
support MIC 222.
With handheld measurements greater deviations are possible. Deviations in
the measurement result caused by plate vibration can be reduced by coupling.
The error data are related to the total error (instrument plus hardness reference plate)
