Explanation of Operation
(1) Continuous measurement is started the moment that the mode changes to the RUN
mode.
(2) When measurement ends and the measurement processing time elapses, the
measured data is applied and output.
(3) Analog output is started after the measured data is applied and the analog output
response time (T3) elapses.
(4) Output is executed for the time specified as the binary output cycle after the IFU
binary output response time (T4) elapses and the measured data is applied.
(5) The GATE signal turns ON for the predetermined time and measured data is
captured on the external device after measured data is applied and the IFU binary
output response time (T4) elapses.
Measurement cycle: High-speed mode (FAST)
T1:
Measurement cycle The measurement cycle is 0.5 ms.
Note, however, that the response time is 1 ms in the IC lead
pitch and IC lead width judgment modes.
T2:
Measurement processing time This is the time required until the measured data is applied.
(max. 1 ms)
Note, however, that the response time is 1.5 ms in the IC lead
pitch and IC lead width judgment modes.
T3:
Analog output response time This is the time until the Controller starts analog output after
completion of measurement. (100 µs)
