Label Height. Regardless of orientation, the measurement taken along the length of a
label’s individual bars.
Label Length. Regardless of orientation, the measurement taken across the label's
bars from one end to the other, including the quiet zone.
Label Speed. The rate in inches or centimeters per second at which a label moves
through the scan beam.
Label Transitions. The transition of bars and spaces on a label, used by the MS-sen-
sor to detect the presence of a label on an object.
Ladder Label Orientation. A bar code label in which the bars are parallel to the label’s
direction of travel.
Match Code. The ability to compare bar code labels being scanned against a master
label that is stored in the memory of the scanner.
Menu Configuration. The process of changing factory default settings via a sequence
of menus displayed on a terminal monitor.
Mil . One thousandths of an inch or 0.0254 mm. In bar-coding, a measurement that iden-
tifies a bar code label by the width of its narrowest element.
Mismatch. An event that occurs when the scanned bar code label does not match the
master label that is stored in the memory of the scanner.
MS-sensor. An FIS option that analyzes label bar and space transitions and reflected
light to determine why a label was not decoded within the triggered read cycle (bad
label, no label, or no object), and displays a message to identify the cause.
Narrow-bar-width. The width of the narrowest bar of a given label, expressed in
thousands of an inch (or mils).
Non-volatile RAM (NOVRAM). Random Access Memory that is available on power-on;
that is, after power to the unit has been recycled.
Noread . A non-read. A condition that occurs when the scanner is set up to decode
labels, and no labels are scanned during the read cycle.
Number of Scans Calculation. The number of times a bar code label is scanned by
the scanner during one pass through the laser beam.
Object Detector. A photo electric device used to sense to presence or absence of an
object (also referred to as a package detector).
Operational Commands . Serial commands from the host to the scanner that control
current operating parameters, counters, master label operations, and program manage-
ment that are not stored in non-volatile RAM.
Picket Fence Label Orientation. A bar code label in which the bars are perpendicular
to the label’s direction of travel.
Pitch. Label (or scanner) rotation around the center a line perpendicular to the label’s
bars.
