Measurement Interval
The pulse integral value each measurement interval is the measured value. When stable
pulses are input, the upper limit of numbers of pulses and the measured values are
shown below.

*2 Exceeds the rated count and therefore measurement is not possible.
*3 When using the SNTP time synchronization function, the values in the upper row are exceeded
therefore measurement is not possible.
Note
• When using the SNTP time synchronization function, the spacing between the measurement
intervals changes. Thus, the measured value for each measurement interval changes, but
this has no effect on the integral value (TLOG.PSUM).
• If you set the measurement interval to something other than 1 s, the measured value cannot
be displayed in units of seconds. To display in units of seconds, set the measurement
interval to 1 s, or use the MATH function (/M1 option).
