Averaging Time and Refresh Cycle
The LS-7600 Series averages measured values in a moving averaging method, thus
making it possible to output the measured values within a short time.
The following table lists the averaging time, the number of moving averaging data items,
and the refresh cycle of a target according to the number of averaging measurements.

❈Measurement averaging time does not indicate the measuring response time of the
LS-7600 Series.
Refer to Measuring Response Time on page 9-5 for details.
Example: If the averaging number is eight, the LS-7600 Series will output the data as
shown below.
