Scan Rate– is the number of times a laser’s scanning beam passes through the exit window in one second.
Scan Velocity– is the speed of a laser’s scanning beam on a target at a given distance from the front of the scanner or rotating polygon mirror. Usually expressed in inches/sec.
Scan Width– is the length of the widest bar code label that can be successfully interpreted by the scanner.
Scanner– is an
SMT– is an acronym for “surface mount technology.”
Specular Reflection Zone – The zone where light from the scanner’s illumination source is reflected directly back into the scanner. Specular reflection interferes with the scanner’s operation. This zone should be avoided.
Start/Stop Characters– are characters used at the beginning and end of a bar code label that indicate the start and stop (end) of the label.
Trigger– is a signal input to the decoder that the scanning process should be initiated. The actual trigger mechanisms can be a push button switch, photoelectric control, internal object sense, proximity sensor, or multiple combinations of all of these.
Usable Scan Length– refers to that portion of the scan path for which the scanner can accurately digitize bar code and maintain all its specifications. This length is specified on a flat surface which is perpendicular to the optical axis of the scanner.
Volatile– refers to the characteristic of a device which loses data in memory when power is lost or turned off.
Voltage Range– refers to the specified range of voltages over which a decoder or a scanner can maintain all of its electrical, optical (for scanners), and environmental specifications.
Voting– is a feature of the SCANTEAM 3700 set by using the Set Votes Configuration Command, Km. If the Voting selection is set to more than 1, the SCANTEAM 3700 decodes and compares consecutive outputs from the scanner(s); successive reads of the same data are required for a valid read. Voting results is a slightly slower read rate, but will reduce the probability of reading errors when a laser scanner, especially, is being used. If the Voting selection is set to 1, only one laser scan resulting in a successful decode is required for a valid read.
