Measurement Response Time

The following table lists the response time between the moment the dimensional
change of a target is detected and the measured result is obtained.

The response time is determined by the corresponding measurement averaging time,
refresh cycle, and internal processing time (2.5 ms).

❈ If the RUN mode is set to normal, auto peak, auto bottom, or auto peak-to-peak, the

response time will be the response time of the comparator output (HH, HI, GO, LO,
LL, WAITING, or STROBE) and BCD output.

❈ The response time of analog output will be the response time of comparator output

plus approximately 0.4 ms.

❈ If the RUN mode is set to peak, bottom, peak-to-peak, average, or sample hold 1,

the response time will be the response time of the internal measured value. Refer to
pages 4-36 to 4-40.

❈ If the RUN mode is sample hold 2 or self-timing, the measured value will be sampled

with a delay of internal processing time.
