I/O Timing Charts

This section explains the I/O signals that are exchanged between the Controller and
external devices, and the timing charts for data output.

T3: When the trigger is detected after it is input, data output changes status from
Output ON to OFF, and this status is held for the following preset time.
response At FIXED sensitivity:T3=T1 x (average number of times + 2) (maximum value)
time At MULTI sensitivity:T3=T1 x average number of times
T4: This is the time from start of output up to when the GATE signal turns ON. This
GATE output time can be changed. This is the time to wait until stable output data can be
delay time obtained.
T5: This is the time that the GATE signal is ON. This time can be changed. This is
GATE ON the time that is required to capture data output (measurement values/judgment
time results) on external devices.
Important
When the auto output for serial output is ON, input the next trigger after all measurement data
is received. At this time, the ENABLE signal turns ON after all measurement data has finished
being sent.
