Time
Description
T0
Trigger ON time. (When effective duration is designated, consider it as effective duration.)
T1
Chattering prevention time. (5 ms)
T2
Buzzer and indication LED illumination time. (Initial value: 200 ms, changing allowed)
T3
Trigger signal minimum OFF time. Be sure to set 30 ms or more.
T4
Communication time. Differs according to communication condition.
• In case of continuous reading and plural reading, laser is always radiating during trigger input is ON
(or during reading effective duration). Concept of T0 to T4 other than this is the same as the case of
single reading.
• A rough guide of reading time
As this bar code reader is approx. 1000 decode/sec., decode process time for once is 1 ms. In case
of plural time conformance, "1 ms x (conformance time + 1)". However, it differs according to the
reading bar code condition (dirt or thin spot, etc.)
