CongurationandOperation
Regula 7517A is a set of hardware components and software products. The device allows
examining objects using different methods.
Examination starts with magnetic copying (making a magnetogram = magnetic copy) of
the ferromagnetic object surface. The magnetic copying accessories set (MCAS) contains
various kinds of magnetic scanners which locally magnetize the object, excite its magnetic
stray elds and copy them to the intermediate exible magnetic carrier (magnetic tape) without
removing the lacquer–and-paint coating. The eddy-current scanner (supplied optionally) is
used for investigating internal stresses in ferromagnetic objects and for examining the surface
of aluminum objects.
The magnetogram is loaded into the USB device for magneto-optical visualization
(MOV USB device) where information about object’s surface layer is scanned. The MOV USB
device combines two functional components: optic-mechanical block and block of electronics.
The optic-mechanical block (OMB) contains a magneto-optical visualizer which converts
magnetic stray elds of a magnetic copy into an image and a special tape drive mechanism
which moves the magnetic copy relative to the visualizer.
A magnetic copy is loaded into the tape drive where it is automatically detected and
introduced into the tape drive tract. Then it is scanned step-by-step by a sensor designed
on the basis of a magneto-optical crystal. Magneto-optical visualization of magnetograms of
the examined object is based on Faraday magneto-optical effect which occurs in crystalline
lms of Bi-containing ferrite garnets.
Light distribution obtained as a result of visualization is received by the sensitive element
of the video camera and is converted into a digital TV signal which is further processed and
examined with the help of PC software.
Step-by-step input of images into a PC allows making automatic panoramic stitching of a
digital image from several sub-shots.
The block of electronics manages OMB resources (electric drive, inductor, illuminator,
video camera and indicators).
The PC operates the MOV USB device via special software. The PC displays newly obtained
and stored examination data which are processed, examined and documented.
Peripherals (supplied optionally) extend examination possibilities of the device by applying
additional methods and means of investigation.
The device operates together with the following peripherals:
zUSB device for optical input,
zmagnetic powder visualization device,
zeddy-current probe,
zelectrochemical etching device.
Basic functions of NUCA (EYER) software:
zoperating USB devices,
zinput and processing of images,
zautomatic program correction and panoramic stitching of MOV frames,
zimage scaling and rotation,
zcomparison of images,
zmeasurements of linear and angular sizes,
zsaving and printing of image les as illustrations to the photo charts.

A set of operational documents contains data on design, principles of operation,
properties of the device and its components. It also contains instructions on correct and safe
device operation and evaluation of its technical condition when deciding whether it is necessary
to send it for repairs.
The device is designed as a compact unit for desktop use. The general view of the device
is given in Figure 1.
Figure1

Means of Measurement, Tools and Accessories
The device belongs to indicating (not measuring) equipment. Therefore control of device
operation is carried out using test-objects, simulating several known methods of number
alteration (cold calking, sealing with fusible metals, dot welding and pressing-in fragments).
See paragraph 2.2.1.2 for the details of the device operational check-up using the test-object.
Test-objectspecications
The test-object (see Figure 2) imitates an examined object. It is a plate (unkilled sheet
steel) with the thickness of 0,8–0,9 mm bearing “291634” original number applied by mechanic
pressing (cold stamping). The original number details: manual stamping with the use of “font
No.6” stamping set and a hammer on a massive anvil. The depth of digit relief is about 0,3–
0,4 mm.
Three digits of the original number were modied: “9” to “0”, “6” to “9” and “4” to “5”.
Thus, the altered number appears as “201935” (altered digits are underlined).
Digit “9” of the original number was altered manually using cold calking of one element
(crosspiece) of digit “9” with the help of bench tools. Then digit “0” was stamped over
the remaining contour of digit “9”.

Alterations of digit “6”. The original number fragment bearing digit “6” was dismantled (cut
out), rotated by 180°, pressed in (so that digit “6” transformed into digit “9”) and then was
xed in the plate frame by spot welding.
Digit “4” of the original number was modied by means of sealing the digit relief with
soft metal (tin) and then stamping a new digit “5” over the built-up area.
After the original digits were altered, the following operations were performed on the test-
object: grinding, spackling, dressing, priming, two-layer spray-on painting with aerosol motor
enamel using the technique of cold drying in accordance with the repaired coating type.
Marking
Device marking is performed in the form of a label on the rear side of the PC panel.
The marking label provides the following information:
zmanufacturer’s name and/or trade mark,
zmanufacturer’s model identication,
zdevice serial number in compliance with the numbering system of the manufacturer,
zdate of manufacturing (year and month),
zrated voltage, V,
zrated current, A,
znominal frequency, Hz,
znational certication mark.
Device sealing is made with the help of destructible security labels applied on the OMB body
and on the device chassis. Damage to the security label causes a loss of warranty.
The SPRK is labeled on the repair kit’s bag.
Packaging
The device is transported and stored in a special cardboard box of the delivery set. Device
components are arranged in conformity with Table 1.

zMT is manually inserted into the OMB buffer. Then MT is captured by the magnetic tape
drive and moved to MOV working zone.
zStep-by-step movement of MT is followed by panoramic stitching of MOV images.
zThe quality of stitching and its informative value is controlled.
zMT extraction: direct or reverse rotation depending on the length of the inserted MT
strip. Manual extraction of MT from the OMB buffer. The device switches to a stand-by
mode.
zThe equipment automatically switches to a stand-by mode when the “Stop” mode lasts
longer than ≈ 5 minutes. The stand-by mode is switched off as soon as a new command
is received.
Magnetic Copying Accessories Set (MCAS)
Functions
zCreating a physical copy (recording information to intermediate exible magnetic carrier —
magnetic tape) of magnetic stray elds distribution over the object surface. The copy reects
relief and structural inhomogeneity of the material. Permanent magnets of the combination
magnetic scanner (CMS) concentrators serve as sources of magnetic stray elds excitation.
zDemagnetizing magnetic tapes for further use.
zArranging, marking, storing and carrying the operating reserve of MT and recorded
magnetic copies.
zService functions while performing magnetic copying.

MCAS case dimensions 120×80×40 mm
Weight of the loaded MCAS case 0,4 kg
CMS dimensions 105×30×30 mm
CMS weight not more than 0,2 kg
Design
The MCAS case is designed as a leather waist carrier pouch intended for carrying accessories
for magnetic copying.
The combination magnetic scanner-demagnetizer (CMS) is intended for magnetization
of an examined object and magnetic biasing of magnetic tape while performing a magnetogram.
It is also used for demagnetizing magnetic copies for their further reuse. The CMS is equipped
with three replaceable concentrators on permanent magnets for use on different surfaces of
objects with various properties:
zat concentrator (effective width of 11 mm),
zrotary concentrator № 1 (effective width of 15 mm),
zrotary concentrator № 2 (effective width of 21 mm).

14
TheCMSatconcentratoris designed for copying relief surfaces with unevenness not
exceeding 0,5 mm at the base width of 11 mm The CMS at concentrator has the strongest
magnetic ow compared to the other scanners. Thus, it is mainly used for examining structural
inhomogeneity of metal surfaces.
Rotary concentrators of the CMS are designed as the system of oating disks for
magnetic copying of more complex relief surfaces with unevenness not exceeding 1 mm at
the base width of 20 mm. The CMS rotary concentrators form surface magnetic ow. Therefore
they are mainly used for examination of relief inhomogeneity of metal surfaces (front side
of the number platform, defective welded seams). They have the highest penetrating ability
through lacquer-and-paint coating. Stronger magnetization is provided by the concentrator
with a smaller effective width. That is why the use of 15 mm concentrator is more preferable
for detailed examination. The use of 21 mm concentrator is more preferable for increasing
the examined area.
The compact magnetic scanner is equipped with a at concentrator on permanent
magnets with effective width of 11 mm. Due to the minimal size the scanner can be used
on difcult surfaces: grooves, joints or abutment of examined object elements. Magnetizing
properties of this scanner occupy an intermediate position among the CMS concentrators.
The compact magnetic scanner is equipped with a spring clip which can be xed in one of two
positions. The operator can choose a suitable position relative to the direction of scanning.
The most effective device for advanced examination of metal structure of objects is
the eddy-current scanner (supplied optionally). Its specications are given in the user’s
guide to eddy-current magnetographing device Regula 7517B.
Magnetic tape cartridges are used for storing operating reserve of MT. The cartridges are
marked: 1) the cartridge for MT that has recorded information is marked with a red marker,
2) the cartridge for demagnetized MT is marked with a green marker. Cartridges can be either
attached to magnetic clamps (Figure 6) or kept separately.
Magnetic clamps are used to x a MT strip on the examined area during magnetic copying.
Use a container with operating reserve of alcohol and a brush when preparing the object
surface for magnetic copying. Use a marker for marking magnetic copies.
Some accessories for magnetic copying and SPRK are kept in the accessories bag:
zCMS rotary concentrator (21 mm),
zcompact magnetic scanner (11 mm) (Figure 10, pos. 1),
zcontainer for alcohol (10 g),
zmarker,

zConnect the PC to an external power supply source. The device can be powered by
the internal (autonomous) PC battery. In this case power supply cables are not connected.
zSwitch on the PC. Start the OS and launch NUCA (EYER) software. As soon as the MOV
USB device is successfully connected, the yellow LED (Figure 3, pos. 3) comes on.
The device is ready to operate.
Operation control
zTake out test-object #1 intended for testing the MOV USB-device (see paragraph 1.1.5)
from the SPRK. Carry out magnetic copying of the test-object in conformity with
paragraph 2.2.2.3.
zPerform magnetic copy stitching in the PC in conformity with paragraph 2.2.1.3.
zCompare the results of obtained magnetic copy stitching with the template shown in
Figure 4. In case of positive results, operation of the unit is considered normal. Criteria of
comparing the obtained magnetic copy stitching results with the templates are as follows:
{Compare the quality of displaying the original metal surface (surface texture
shall be visible).
{Compare the quality of displaying original number digits alterations (traces
of mechanical processing on the 2nd, 4th and 6th digit positions, as well as
traces of spot welding and contours of pressing-in fragments on the 4th digit
position shall be visible).
{Compare the quality of displaying residual digits of the original number that
were altered (fragments of the original number digits shall be visible on
the 2nd and 6th digit positions).
zIn case of malfunction at any stage of operation control, see paragraphs 3 and 4.
Switching off the MOV USB device
To switch the device off, do the following:
zExit NUCA (EYER). The yellow LED (Figure 3, pos. 3) goes off and the device enters
sleep mode. Exit the OS and switch off the PC.
zUnplug the PC (if it was connected to the mains).

2.2.1.3MOVUSBdeviceintendeduse
The MOV USB device performs the following operations:
zmagnetic copy stitching,
zextracting a used magnetic copy,
zprocessing and analyzing magnetic copy stitching,
zdocumenting examination results.
Magnetic copy stitching:
zEnsure that no magnetic tape is present in the OMB tape drive tract — neither the red
LED “MT in the buffer” (Figure 3, pos. 3), nor the green LED “MT in the tract” (Figure 3,
pos. 3) is on. Otherwise, rst remove the previous magnetic copy.
zFor plastic MT. Put the MT with its working surface (of brown colour) facing
down (facing the MOV USB device). It should be noted that when using ½’’ MT, it is
inserted into a paper cartridge beforehand. Then put the ½’’ MT with its working surface
(of brown colour) facing down while the paper cartridge is located on top of MT.
zStraighten MT holding it by its edges and insert it into the tape drive (Figure 3, pos. 1).
Move MT into the tape drive to a depth of 30 mm (until blocked). The red LED (Figure 3,
pos. 3) lights up conrming the state “MT in the buffer” and the electric motor starts to
capture the tape. Move the tape further inside the tape drive tract until it is captured by
the drive shaft of the OMB. The green LED (Figure 3, pos. 3) lights up conrming the state
“MT in the tract”). Release the MT strip and it will move forward automatically.
zWait for approximately 5 seconds to load the potentially informative sector of the magnetic
copy into MOV zone. Start the stitching process by corresponding software command.
The stitching process is conrmed by the green LED blinking (Figure 3, pos. 3) with
the meaning “MT in the tract”. The rst visualization sub-frame appears on the PC screen.
zControl the quality of stitching visually. When signs of low quality of magnetic copying
are observed (due to MT non-contact with the examined surface, MT or scanner warp
during copying, etc.), it is possible to stop the stitching process by clicking “Eject MT”.
As soon as MT is returned to the buffer, extract it, demagnetize, and make another
magnetic copy in conformity with paragraph 2.2.2.3.
zIf magnetic copy quality is satisfactory, stitching can be continued until the end of
the informative MT area and then stopped by clicking “Eject MT”, or you can wait until
OMB stops in automatic mode (“MT end” LED comes on).
Extraction of the used magnetic copy
zAs soon as the command “Eject MT” is executed by the OMB, used MT automatically
returns to the buffer — to the tape drive or to the bunker (to the closest location).
The green LED “MT in the tract” fades and the red LED “MT in the buffer” comes on
indicating that MT stopped moving. Do not remove an MT strip from the tape drive
until it stops completely and the LED “MT in the tract” is off!
zTake MT by its edges and remove it from the buffer. The red LED “MT in the buffer” is to
go out. Then the used magnetic copy is to be demagnetized for reuse and placed into
the CMS case or it should be stored for further use.

19
Processing and analyzing magnetic copy stitching
zRotate the stitched copy to match the original, using manipulation functions: image
rotation and mirror imaging.
zEvaluate the quality of stitching visually. If the quality is satisfactory, save the initial
le and start processing and analyzing. If the quality is unsatisfactory, repeat magnetic
copy stitching or make a new magnetic copy.
zProcess the stitched image using software functions. In general the following functions
give the most effective results: threshold processing with the possibility of brightness
levels band spreading, image differentiation and spatial ltering.
zAnalyze magnetic copy stitching:
{Visually determine if there are any signs of number alterations. The main
signs of alterations examined are the following: traces of mechanical
processing taking the form of traces or nicks (Figure 4: 2nd, 4th and 6th digit
positions); original number fragments (Figure 4: 2nd and 6th digit positions);
non-ferromagnetic materials fragments (Figure 4: 4th digit position); welded
seams and borders of pressing in (Figure 4: 4th digit position).
{Additional signs of number alterations examined are the following: deviation of
form and arrangement of digits in the number; different intensity (clearness)
of the number digits contour; non-uniformity or absence of the object surface
texture processing. It should be taken into account that the last two features
can result from a poor quality copying (magnetic tape does not t closely to
the surface).
{Compare the images of the digits with the specimen numbers of this model of
rearms or with digits repeated in the examined number.
{Measure geometric dimensions of the images of the digits and analyze their
position. The software allows measuring linear and angular image dimensions.
zAnalyze examination results.
Documenting examination results
zSave the initial le of magneto-optical visualization of the number platform. It is also
possible to save processed images.
zThe magnetic copy can be saved as material evidence.
zPrint the obtained images.

Theorderofrelling
Consumables: MT, ethyl alcohol.
To ll up the operating reserve of MT, do the following: take MT from the SPRK, cut it into strips
of necessary length and enclose them into the cartridge intended for storing MT (Fig. 6, pos. 1).
To cut metal MT, use the cutter from the SPRK and do the following:
zSet the cutter lever (Figure 5, pos. 1) in the upper position, letting the tape freely pass
through the slot as shown in Figure 5a.
zPush the MT strip in the area marked as 6 (see Figure 5a) to move the MT strip
(Figure 5, pos. 3) through the slot beyond the edge of the blade (Figure 5, pos. 2).
zTake the MT by its edge (Figure 5, pos. 3) and pull it out for a required length, relative
to the blade edge (Figure 5, pos. 2). The cutter body (Figure 5, pos. 4) can be used
for measuring the approximate length of the MT strip. A full loop of the tape around
the body is equal to the operating MT strip length — 250 mm.
zLower the cutter lever (Figure 5, pos. 1) and slightly press it down to x the tape as
shown in Figure 5b.
