Introduction
Important notes
1.1 Important notes
GE Inspection Technologies Operating manuals provide functional information about a particular instrument or group of instruments. However, proper setup and use of this equipment and the performance of
electromagnetic tests requires familiarity with factors
which are beyond the scope of Operating manuals.
These factors include the following:
• Selection of appropriate cables, probes, fi xtures,
mechanical handling equipment and other accessories.
• Selection of proper test frequency, test mode and
other test parameters.
• Preparation of the test surface.
• Characteristics of the test material for example: conductivity, hardness, permeability, geometry, magnetic properties, heat treatment etc.
• Environmental factors such as temperature humidity, dust and electrical interference.
• Any individual factors that will depend on the particular test object or test being performed.
It is therefore imperative that operators are properly
trained in both general procedure for electromagnetic
training testing and in the set up and execution of the
particular test to be performed. It is the responsibility
of the instrument user to ensure that test operators are
trained to a suffi ciently high standard, suitable equipment is used in the correct manner and that any test
variables which may affect specifi c tests are taken into
account. Similarly, compliance with standards such as
ASTM, ASNT, API, ASME, BS etc., as well as the observance of any test procedure specifi ed by any government, manufacturer or other regulating authority is
the responsibility of the user.
Periodic calibration, cleaning and maintenance may
be necessary to ensure proper operation of the equipment.
Environmental conditions and regularity of use should
be considered when determining the frequency of
such checks, then this should be observed.
Incidents such as physical shock, immersion in liquid
and exposure to damaging environments such as excessive heat, moisture, dirt or dust can adversely affect equipment performance. The equipment must be

Introduction
examined for damage and recalibrated after any such
incident. Do not use any product which you know or
suspect to be faulty.
Reference samples used for calibration should, ideally,
have the same material properties as the object to be
tested, or a known relationship to it, established by a
laboratory test.
Equipment calibration should be checked frequently
during testing to assure valid test measurements.
As a matter of good practice and wherever possible,
suspected defects in critical areas should be cross
checked using appropriate alternative indication techniques.
Any question about the use, operation, specifi cations
or special considerations relative to the particular
GE Inspection Technologies product you are using
should be addressed to your local sales representative,
the distributor or GE Inspection Technologies direct.
Eddy current based instrumentation works by measuring minute electromagnetic fi elds. Interfering signals,
even at a level satisfying CE mark requirements, may
be able to mask or distort this information. The user is
responsible for ensuring that no such effect is occurring.
GE Inspection Technologies pursues a policy of continued development of its products. The company reserves the right to change specifi cations without prior
notice.

Battery installation
3.1 Battery installation
Power requirements
The AutoSigma 3000 can only be operated by battery,
using three AA size cells, Alkaline (preferred), Dry
Cell, or Ni-Cad .
H
Note:
If Ni-Cad batteries are used the battery level indication will not be correct, and they should be removed
for charging when the level indicator shows about
25 %. The AutoSigma 3000 has no provision for in situ
charging.
– Undo Battery Cover Screws and lift off the cover
(the screws are captive in the lid).
– Insert three AA alkaline cells as shown.
Alternative cells may be used if alkaline batteries are
not available, but unit operating time may be reduced
and battery level indication inaccurate.
If the batteries are installed incorrectly with the polarity
reversed, no damage to the AutoSigma 3000 will occur, but the instrument will not function.
– After the batteries have been installed, replace the
battery cover and refi t the screws. The Icon on the
display shows the battery charge.

Note:
When the battery empty state is displayed, the batteries should be replaced at once.
The AutoSigma 3000 automatically turns off when
the batteries become too weak for reliable operation.
When using the equipment in remote locations it is advisable to carry spare batteries. Discharged or faulty
batteries are classifi ed as Special Waste and must be
disposed of accordingly.
Preparation for operation
3.2 Probe connection
The connecting cable for the probe is a 5 way LEMO
to 5 way LEMO and may be used either way round.
– Align the red dots of the LEMO plug and the socket
of the cable and plug together, they are polarised
and will therefore not engage unless correctly mated.
– Similarly attach the cable to the instrument.
The connectors are self locking and will not become
detached without being released by pulling the serrated section of the plug.
H
Note:
Before a probe can be used to take accurate measurements, its Code Number (if not already contained in
the probe fi le) must be entered into the instruments
operational memory – see section 3.3. Instruments
supplied from the factory with a probe will already
have the code number entered. 12.7 mm diameter
probes have a 4 digit code and 8 mm diameter probes
a 2 digit code.

Basic measurement knowledge

3.7 Basic measurement knowledge
Conductivity of metals is commonly measured in two
sets of units. In the SI system the unit of conductivity
is the MegaSiemens/meter (reciprocal ohm-meter).
Conductivities of metals at ambient temperature are
typically in the range of 1 to 60 MegaSiemens/meter.
For convenience metal conductivities are often expressed as a percentage of the conductivity of a standard sample of copper – the International Annealed
Copper Standard (IACS). 100 % IACS corresponds
to 58 MegaSiemens/meter. Note that since this “pure”
copper standard was established in 1913 pure copper
now often has a conductivity greater than 100 % IACS.
The AutoSigma 3000 measures the conductivity of
non-magnetic metals and alloys in the range 0.8 to
110.0 % IACS. It uses the Eddy Current technique for
measuring the conductivity of materials in % IACS, or
MegaSiemens/meter (set from the instruments menu
selections).
It is important to understand that eddy current measurement is essentially a “skin” effect. The eddy current fi eld intensity is greatest at the surface and decreases exponentially with depth. The depth at which
the fi eld strength reduces to 1/e (37 %) of its surface
value is referred to as the “standard depth of penetration”. This depends primarily on the operating frequency and the conductivity of the metal.
It is generally considered that materials of thickness
greater than three standard depths of penetration can
be measured without any correction factors being required.
For example at 60 kHz this fi gure (the “effective depth
of penetration”) is around 0.05" (1.25 mm) in Aluminium Alloys (conductivity approximately 35 % IACS) and
0.32" (8 mm) in Titanium alloy (conductivity approxi-
mately 1 % IACS). At 500 kHz the corresponding values are 0.02" (0.5 mm) and 0.11" (2.8 mm).
Care must also be taken when measuring non-homogeneous materials, for example materials which have
been surface heat-treated, clad or plated, or where the
surface is rough or corroded. Measurements at different frequencies will give different results due to the
AutoSigma 3000 Issue 04, 06/2007 3 - 9
Page 26
Preparation for operation
Basic measurement knowledge
different distribution of energy within layers of different conductivity. Care must be taken to always measure such materials at the same frequency (usually
60 kHz).
The conductivity of a material changes considerably
with temperature, but is normally specifi ed at 20 °C.
The AutoSigma 3000 indicates the materials 20 °C
conductivity value by applying a standard correction
algorithm, valid for the most common aluminium alloys. For the best accuracy, the instrument, material to
be tested, probe, and calibration standards should be
at the same temperature, close to 20 °C.
Other key factors are coating thickness/lift-off and material curvature.
Measurements can be made through layers of paint
or other non-conductive coatings up to a thickness of
0.020" (0.5 mm) with the 12.7 mm probe and 0.010"
(0.25 mm) with the 8 mm probe.
Use on curved surfaces requires some caution, with
concave surfaces the effect is primarily lift-off and the
instrument will compensate up to the point where the
spacing of the centre of the probe from the material
becomes excessive. With convex surfaces the indicated conductivity will decrease as the radius decreases.
Correction tables are required for radii below approximately 3" (75 mm).
To ensure proper operation the calibration standards,
instruments and probes should be checked and recalibrated on a regular basis (e.g. check on standards before each use and factory re-calibration every year).

Measurement method
4.1 Measurement method
The instrument uses a probe which is excited by an
AC signal (60 kHz “L” or 500 kHz “H”) from the main
unit. This AC signal uses the material to be measured
as a coupling medium to a detector coil also in the
probe. From the phase and amplitude of the detected
signal the instrument calculates the conductivity of the
coupling medium.
Only conductivity of non-magnetic metallic materials can be measured using this system. Conductivity
changes considerably with temperature so the probe is
fi tted with a thermistor. It’s temperature is monitored in
order to display a mathematically adjusted conductivity
reading relative to 20 °C. The instrument will indicate
the necessity for a Probe Reset after a temperature
change of +/–3 °C. The set routine should be carried
out just before a measurement if absolute accuracy is
required.
A certain amount of surface unevenness and nonmetallic
coatings up to 0.020" (0.5 mm) are allowed for in the
measurement system (0.010" (0.25 mm) only with the
8 mm probe). When the probe has exceeded this “liftoff” distance, PROBE OFF METAL will be displayed.
4.2 Display
The display is a back lit LCD, the back light can be set
ON or OFF. When in Measurement Mode the display
will indicate the numerical value of the material being
measured in % IACS (I) or MegaSiemens/meter (S)
depending on the units selected. PROBE OFF METAL
is displayed if the probe is in air and not in close proximity to a measurable material.
Other display modes can be selected which are used
for setting up operational parameters, or logging fi les
(see chapter 5). In these Modes the display will highlight the parameter being set and its current status. In
the measurement mode Alarm States are indicated
by icons at the bottom of the display. The frequency,
probe code selected, measurement units and state of
charge of the battery are also shown at the bottom of
the display.

Operation
Switching on
5.1 Switching on
– Press ON/OFF.
The instrument switches on in the normal Measurement mode and will operate according to previously
set parameters. A SET PROBE routine should be carried out before use (see section 5.5) The display will
show the conductivity of the material on which the
probe is placed or PROBE OFF METAL if the probe
is in air. The display also shows information such as
the operating frequency, measurement units, probe
code number, battery state and alarms (see below).
Also the word SET will appear on the bottom line if the
probe temperature has drifted +/–3 °C since the last
set routine was carried out. If the SET icon appears
then the set probe routine should be carried out to restore high accuracy measurement.
Example
Taking a reading of 60.5 % IACS (I) at a frequency of
500 kHz (H) with a probe whose code number is 5467.
At the bottom right a battery level of 50 % is indicated
and to its left the presence of the
upper alarm level has been exceeded.

5.2 Switching off
– Long press ON/OFF.
The instrument will beep twice if settings have been
changed and power down.
5.3 Changing working parameters
Follow the sequence in section 3.5.
H
Note:
The settings of some parameters are dependent on
others and if a confl ict is encountered error messages
will appear on the screen and/ or the instrument will
beep. Some are as follows:
With an 8 mm (two digit) probe code in place, you cannot select a frequency of 60 kHz (only useable with
12.7 mm probe). If it is attempted the instrument will
beep and not carry out the change. It is then necessary to move to the PROBE parameter and recall
the correct four digit code number appropriate to the
12.7 mm probe to be used.
When the set probe routine is being carried out, if the
wrong probe code is in place i.e. two digit number is
present (8 mm probe) when trying to set a 12.7 mm
probe which should have a four digit code number or
vice-versa. The display will show an error (see Figure below), and will prompt a press of the SET button

When the code number has been incremented to the
correct one, a press on the MENU button will take the
instrument back to the normal measurement display
which has the code indicated on the bottom line and

– To re-commence the set probe routine, once the
correct probe code has been entered, press SET.
5.4 Entering reference block
values
Before the AutoSigma 3000 DL can be set, the reference block values need to be entered. It is recommended that the STD blocks supplied with the unit are
used as these will provide the most effective and accurate setting. As an alternative user reference blocks
may be used, these will limit the instruments range
and can reduce accuracy.
Ensure that the instrument is set to the correct units
for the block values to be entered. If not change the
UNITS parameter value fi eld before moving to the STD
parameters and entering the block values. From the
normal measurement mode proceed as follows, e.g.
setting STD 1 (60.1) and STD 2 (8.91).

User reference blocks
Can be used to set the AutoSigma 3000 DL, provided
that
• STD 1 is within the range 30 to 63 % IACS,
• STD 2 is within the range 6 to 50 % IACS and
• STD 1 is at least 10 % IACS above STD 2.
The values are entered in the unit in the same way as
the STD blocks.
Considerations
If user reference blocks are used, accuracy can be
compromised and range limited.
AutoSigma 3000 Issue 04, 06/2007 5 - 5
Page 36
Operation
Entering reference block values
The absolute accuracy of the instrument will be dependent on the accuracy of the user reference blocks and
will no longer be to the accuracy stated in the “Specifi cations” chapter of these instructions. It is not recommended that measurements are made outside the
range of the two sample values; as the accuracy will
be totally dependent on the absolute accuracy of the
user reference blocks.
For the relative reading accuracy to be the same as
for GE Inspection Technologies STD blocks, the two
user reference block values must be accurate and lie
either side of the measurement range. e.g. If the measurement range is to be between 40 and 45 % IACS
then STD 1 should ideally be 50 % IACS or more and
STD 2 should be 35 % IACS or less.
It is possible to set the AutoSigma 3000 DL by using
one user reference block and one STD block, provided
that the above rules are complied with, the absolute
accuracy will again be dependent on the accuracy of
the user reference block.
5.5 Probe setting (SET PROBE)
Before the probe setting on the reference blocks can
take place, the value of the blocks must be entered in
the STD 1 and STD 2 menu slots in the units selected
(i.e. IACS or MS/m) The probe code must also be appropriate to the probe in use. Proceed following section 5.4 to set the reference block values. Then with
the instrument on and in the Measurement mode:

Notes:

If the calibration process has been interrupted during
the procedure the system will time out (indicated by
fi ve short beeps) after approximately 6 seconds and
return to the measurement mode with the setting factors unaltered.
If the blocks are used in the wrong sequence or the
probe has not contacted the STD’s correctly, the
display will indicate VALUE OUT OF RANGE SEQUENCE WILL RESTART the procedure will then
restart at step 1 as in the table above. This setting
procedure can be aborted at any time by pressing the
MENU button.
Because the air temperature can be different from the
STD sample temperature, it is recommended that the
probe is placed on the STD, for approximately 10 seconds prior to the set procedure and held on each block
for 5 seconds before SET is pressed (steps 3 and 4
above). By allowing the probe temperature to settle to
that of the STD blocks optimum setting is ensured.

Taking a conductivity measurement
5.6 Taking a conductivity
measurement
Ensure the instrument is on and in Measurement
mode see section 5.1. Carry out set probe routine as in
sections 5.4 and 5.5.
With the probe in air the display should be as below.
With (H) if 500 kHz is selected or (L) if 60 Hz is selected. The battery indication should show some content,
and if the icon shows empty new batteries should be
fi t t e d .
The instrument is now ready to take a measurement.
The probe should be at the same temperature as the
material to be measured, if there is a difference the
probe and STD blocks should be allowed to stabilise
on the surface of the material to be measured. The set
probe routine should then be carried out at the temperature the measurements are to be taken at.
Place the probe on the surface of the material to be
measured, making sure it is as fl at as possible on the
surface and not overhanging the edge, the display will
then indicate the conductivity in the units selected.
If the material’s ambient temperature drifts beyond
+/–3 °C the display will indicate that a probe set routine is advisable. (SET will appear on the bottom line
of the display).
If measurements are to be carried out on round bars
or curved surfaces the correct probe and guide should
be used for ease of use and accuracy of results.
