Reset
To reset the TLOG computed value at each interval, select On.
The figure below illustrates the reset operation of sum computation (TLOG.SUM).
Example: Result of the TLOG.SUM computation
When reset is On, the sum value is computed over each interval. When set to Off, the sum
value from computation start is computed.

On/Off
Set this to On to perform rolling average.
Interval
Set the sampling interval for performing rolling average. The sampling interval takes on a
value that is an integer multiple of the scan interval. For example, if the sampling interval is
set to 5 s when the scan interval is 2 s, the actual sampling interval is 6 s.
Number of samples
Set the number of samples for performing rolling average.
The rolling average time is equal to the sampling interval × the number of samples.
Note
• If the number of data points to be averaged has not reached the specified number of samples
immediately after computation is started, the average of the available data is computed.
• Computation error data is excluded from the rolling average computation.
• If the computed data exceeds the upper or lower limit, the data is clipped at the upper or lower
limit, and the rolling average is computed. The upper and lower limits are “±100000000” ignoring
the decimal point. The decimal place is the same as that of the span lower limit.
