Description
TT = Reading gate duration
In Percent Evaluation Mode this time is directly related to the set scan frequency and scan
expenditure (CA) which is always 100.
MG = Average reading evaluation
n = Number of bar codes detected
DEVE592DAAAJ = Bar code data
C39 = Code 39 (symbology)
ST = Error status
CP = Code position
CL = Code length
CA = Scan expenditure (in this mode of operation always 100 scans)
CS = Code reliability
CK = Code continuity
PERCENT EVALUATION
Percent Evaluation is a continuous scanning mode that generates statistical information used mainly for alignment and adjust-
ment (optimal beam position) when installing the CLV. This operating mode is activated only via the terminal emulation screen of
CLV Utility Software. Table 3-5 shows three examples of statistics generated in this mode.
Figure 3-29 Percent Evaluation
In Percentage Evaluation with 100 scans per reading interval, the “Result LED” indicates the trend in the read quality as follows:
LED off
LED blinks (frequency 2 Hz)
LED blinks (frequency 5 Hz)
LED lights up constantly
good read rate <30%
good read rate 30%...70%
good read rate 70%...90%
good read rate >90%
