* The sampling cycle(T2) differs according to the manufacturing variations of individual measuring units.
* The sampling cycle(T2) differs according to the settings of "Scan width/interval".
* The measurement response time, average measurement time, update cycle (T5), and RESET time (T4) vary according to the
change in the sampling cycle (T2).
* The minimum input time (internal processing time, binary strobe cycle) (T1) varies according to the setting of FINE mode.

* T2 is a sampling cycle.
* Number of times for averaging raging from 256 to 4096 can only be selected when the scanning width/interval is set to OFF in the
displacement mode. Refer to "SCAN" (page 3-15) for details.
* Average measurement time does not mean measurement response time. Refer to "Measurement Response Time" (page 9-6)
* The moving average is used for the measured value averaging function. Refer to "OUT (Output)" (page 5-8) for details.
