Intended Use of Device Components
MOV USB device
2.2.1.1 Restrictions on the use
z
It is possible to examine ferromagnetic materials only (iron, steel, cast iron).
Nonferromagnetic materials (aluminum) are examined with the corresponding scanner
of the eddy-current magnetographing device Regula 7517B.
z
Do not use damaged MT (having breaks with sharp edges, strongly crumpled), MT
with bent on edges or dirty MT (see paragraphs 2.2.2.2 and 3.2). Failure to observe
these requirements may result in discrepancies during MT stitching and MT jamming in
the МОV USB device.
z
Avoid large abrasive particles (dust, sand, scale, etc.), oils, preservatives and other
objects (coins, paper clips, etc.) getting into the OMB tape drive.
z
Do not interfere with MT movement in the OMB tape drive tract. Do not try to extract an
MT strip manually when it is automatically moving in the OMB tract.
z
Do not reinstall the OS and drivers for the device components.
z
Do not change settings of the special software. If it is necessary to reinstall the software,
follow the instructions given in the corresponding software User’s Guide.
z
Do not change the arrangement of USB cables connecting the device components and
PC slots. The change in cables arrangement may require drivers reinstallation.
2.2
2.2.1
Do not use MT strips shorter than 150 mm. Otherwise there won’t be a
possibility of manual tape removal in case of tape jamming in the tape drive.
This situation may require qualified service.
2.2.1.2 Preparing for use
Switching on the MOV USB device
z
Connect 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.
z
Switch 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
z
Take 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.
z
Perform magnetic copy stitching in the PC in conformity with paragraph 2.2.1.3.
z
Compare 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).
z
In 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:
z
Exit 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.
z
Unplug the PC (if it was connected to the mains).
