This section explains the timing of the buzzer and LED indication.
In case of reading OK (single reading)
Time
Description
T0
Trigger ON time. Keep the external trigger ON for at least 50 ms.
The reading time depends on the “trigger effective duration” setting.
T2
Reading valid time. (The factory default setting is 2 sec. It can be changed.) In case of reading
OK, the illumination LED turns off and the reading operation finishes as soon as the operation
succeeds.
T3
Buzzer and indication LED illumination time. (The factory default settings are 50 ms for the
buzzer and 200 ms for the indication LED. They can be changed.)
T4
Communication time. This differs depending on communication conditions.
T5
Trigger signal minimum OFF time. Be sure to set 1 s or more.
• In case of continuous reading and plural reading, illumination light is emitted throughout the reading
effective duration that starts when a trigger is input. The concept of T0 to T4 is the same as that in
the case of single reading.
