6. Sweeps per Second SPS is the user programmable number of raster sweeps that transpire in a second A sweep is defined as a single pass up or down describing the raster image Sweeps per second should generally be as few as possible in order to maximize the number of scans applied to a given label and to minimize wear on the raster parts and vibration to the scanner l wn mp Ss 3 a 53 a The formula for finding Sweeps Per Second SPS is as follows 2x Ls SPS SW LL Since SPS can only be entered into the software see Raster Setup Menu on page 2 37 as whole numbers round off fractions of SPS to the next higher number for example enter 0 4 as 1 and 3 5 as 4 Number of Scans NS be calculated by the following formula 2 vs LHXSR _ RH x SPS Example If SW 10 LL 2 and LS 2 then SPS will equal 0 5 Since 0 5 is less than one we will assign a value of one in the Sweeps per Second option as described in Raster Setup Menu on page 2 37 and in the NS for mula which with LH 1 SR 400 RH 10 and SPS 1 calculates out to 37 complete scans 1 The number 2 in the SPS formula is a constant that doubles the number of sweeps to ensure that each label receives two full raster sweeps 2 The 3 component is added to allow for AGC acquisition and for incomplete first and last scans This applies only if the calculation in the brackets is 3 or more If it equals 2
