Appendix A – Operating the LVS-9580 DPM Verifier
The LVS-9580 DPM Verifier is a Direct Part Mark (DPM) verifier. The LVS-9580 DPM Verifier can be used
to verify the symbol quality and structure of a Data Matrix symbol that is permanently affixed to a
manufactured item. Correct application standards must be used to verify the structure of the data contained
in the direct part mark. This list of available standards is located on the Setup Screen. The software is
programmed to use the following application standards:

DPM ISO/IEC TR29158:2011(E)

DPM + MIL-STD-130N w/Change 1 (16NOV2012)

DPM + UII + MIL-STD-130N w/Change 1 (16NOV2012)

GS1 TABLE 7 DPM (non-medical)

GS1 TABLE 7 DPM (medical-ink)

GS1 TABLE 7 DPM (medical, Direct A, connected)

GS1 TABLE 7 DPM (medical, Direct B, not connected)
The LVS-9580 DPM Verifier can be used as a print quality verifier (15415/15416, GS1) and can verify
according to DPM verification standards (ISO/IEC TR29158, MIL-STD-130, UII, and GS1) provided that
those upgrades have been purchased.
The LVS-9580 DPM Verifier can also operate in conjunction with the LVS-9510 Verifier. Both the LVS-9580
DPM and LVS-9510 can be connected to the same computer, allowing you to switch between devices.
Note: The LVS-9510 does not support DPM verification.
DPM Verification
DPM verification does not follow the same rules as traditional 1D and 2D verification. Differences:

All dot peen symbols must now be read with the L-pattern placed squarely in the field of view.

Symbol Contrast is no longer measured. SC (Symbol Contrast) has been replaced with a new
parameter called Cell Contrast (CC). A cell contrast value of 30% is now an A Grade .

Modulation and Reflectance Margin are no longer measured. These two parameters are replaced with
a new parameter called Cell Modulation (CM).

The LVS-9580 DPM Verifier can grade a direct part mark on most surfaces. The usable field of view is
now limited to
1.75” (44mm) by 1.75” (44mm) .

Average Grade (AG) is no longer reported. A parameter called Distributed Damage Grade (DDG) has
taken its place. DDG indicates the average of the notional damage grade at the D Grade level.

A parameter has been created called Minimum Reflectance . A Minimum Reflectance greater than or
equal to 5% is considered to be an A Grade (4.0) . If it is less than 5% then it is an F Grade (0.0).

The final grade now reports additional information:
DPM4.0/12/660/D
o
DPM = Indicates that the DPM rules have applied to the final grade.
o
4.0 = Indicates the final grade point average. This final grade will always be a whole number.
o
4.0 = A Grade, 3.0 = B Grade, 2.0 = C Grade, 1.0 = D Grade, 0.0 = F Grade.
o
12 = Aperture Size
o
660 = Color of the light. 660 = red.
o
D = Angle of the light source. A D angle indicates a dome light.
