Timing details
■ Minimum input time (T1) and input response time (T2)
The sampling rate can be changed according to the setting. Refer to page 3-39.
The measurement response time, measurement average time, RESET time, and refresh rate vary depending
on the sampling rate. Furthermore, when the mutual interference prevention function is turned on, calculate the
value after doubliug the sampling rate (T6 = T6 x 2).
■
Average measurement time, RESET time (T4) and refresh rate (T5)
When the mutual interference prevention function is turned on, calculate the value after doubling the sampling
rate (T6 = T6 x 2).
■ Program No. change time (T7)
When the mutual interference prevention function is turned on, calculate the value after doubling the sampling
rate (T6 = T6 x 2).
