Here, it is assumed that the reading time is "trigger controlled".
Reading valid time. (The factory default setting is 2 sec. It can be changed.)
T2 In case of "trigger controlled" and reading NG, the illumination LED turns off and the reading
operation finishes as soon as the external trigger turns off.
T3 When the error message output is set to ON, this is the indication LED illumination time.
This is the error message transmission time when the error message output is set to ON. 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.
