Explanation of Operation
(1) When the measurement trigger signal is input, the ENABLE signal turns OFF after
the trigger input response time elapses.
(2) Measurement is executed for the preset average number of times. (In the example,
the average number of times is set to 4.)
(3) When measurement ends, the applied measurement data is output after the output
response time elapses. When the ENABLE signal changes status to ON, the next
trigger can be accepted.
(4) When the GATE output delay time elapses after start of output, the GATE signal
turns ON for the specified time, and measurement data is captured on the external
device.
External output at trigger measurement (AUTO sensitivity)
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.
T1:
Measurement cycle The measurement cycle can be checked by the ECO monitor in the
RUN mode.
p.54
T2:
Trigger input response time This is the time from input of the measurement trigger up to when
input is recognized as the trigger. 500 µs or less
T3:
Output response time When the trigger is detected after it is input, data output changes
status from ON to OFF, and this status is held for the
“measurement cycle (T1) x 2 or less.”
T4:
GATE output delay time This is the time from start of output up to when the GATE signal
turns ON. This time can be changed. This is the time to wait until
stable output data can be obtained.
T5:
GATE ON time This is the time that the GATE signal is ON. This time can be
changed. This is the time that is required to capture data output
(measurement values/judgment results) on external devices.
