Glossary - 5
M
MIL.
1 mil = 1 thousandth of an inch.
Misread (Misdecode).
A condition which occurs when the data output of a reader or interface controller does not agree with
the data encoded within a bar code symbol.
N
Nominal.
The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and negative
deviations from this value.
Nominal Size.
Standard size for a bar code symbol. Most UPC/EAN codes are used over a range of magnifications (e.g.,
from 0.80 to 2.00 of nominal).
NVM.
Non-Volatile Memory.
O
Open System Authentication.
Open System authentication is a null authentication algorithm.
P
Parameter.
A variable that can have different values assigned to it.
Percent Decode.
The average probability that a single scan of a bar code would result in a successful decode. In a
well-designed bar code scanning system, that probability should approach near 100%.
Print Contrast Signal (PCS).
Measurement of the contrast (brightness difference) between the bars and spaces of a
symbol. A minimum PCS value is needed for a bar code symbol to be scannable. PCS = (RL - RD) / RL, where RL is
the reflectance factor of the background and RD the reflectance factor of the dark bars.
Programming Mode.
The state in which a scanner is configured for parameter values. See
Scanning Mode
.
Q
Quiet Zone.
A clear space, containing no dark marks, which precedes the start character of a bar code symbol and follows
the stop character.
