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 5-35 to 5-40.
❈ If the RUN mode is sample hold 2 or self-timing, the measured value will be sampled
with a delay of internal processing time.

Focus Characteristics
The following table shows typical examples of the ranges where the FOCUS display or
the FOCUS output turns on, provided that the focal point is at the center of the
measurement area.
