2.5 STABILITY LEDs
STABILITY LEDs allows you to easily check reading stability.
STABILITY LEDs light only when the test mode gets started or the decode count
adding function (see P. 34) is used.
Indication of reading stability
When reading rate check mode is selected
STABILITY LEDs light according to the reading rate shown in the table below. Al-
though, in the test mode, the unit does not output an OK/NG singnal, the OK/NG
LED lights as below. (Comparison to the preset data is not performed.)
When tact check mode is selected
STABILITY LEDs light according to the scan count (decode count), which indi-
cates the number of successful reads, as shown in the table below.
Although, in the test mode, the unit does not output an OK/NG signal, OK/NG LED
lights as below. (Comparison to the preset data is not performed.)
When using the decode count adding function
STABILITY LEDs light as shown in the table below according to the decode
count.
OK/NG output (OK/NG LED) turns ON/OFF based on the result of comparison to
the preset data.
When you do not use the decode count adding function or use the multi-label read
mode 3, STABILITY LEDs do not light.
