Parameter Overview
Trend Analysis — Output 1 and 2
Useful in cases where you do not want to shut down for one condition but want
to monitor quality and read conditions. Applies Trend Analysis settings to
Output 1. With Trend Analysis, you can track the occurrences and frequency of
mismatches, No-Reads, and the number of reads per trigger, and output the
results to any of three outputs.

Mode
Sets the trend condition (Mismatch, No-Read, or Decodes per Trigger) that
activates the output.
– Mismatch
Output activates when the number of mismatches equals the value that
is entered for Number to Output On within the trigger window that is
selected in Number of Triggers.
IMPORTANT
Trend Analysis (Output 1) is shown as an example in
and
. Trend Analysis (Output 2) has the same options.
EXAMPLE
Trend Analysis Mode = No-Read
Trigger Evaluation Period= 25 triggers (read cycles)
Number to Output On = 4
In this example, the code reader activates an output when four No-Reads
occur within a period of 25 triggers (read cycles).
IMPORTANT
Output On under Output 1 Parameters must be set to Trend Analysis for this
output to function.
• Default: No-Read
• Options: 0 = Mismatch
1 = No-Read
2 = Decodes per Trigger
