Resetting the computed result
You can select whether to reset the computed result when the end of the interval is reached or to retain
the result and continue with the calculation.
Example: Result of SUM computation
Scale Settings for Statistical Calculations
When using a time-based summation (SUM) function for obtaining a to talized flow rate or the like, the
unit of the base time can be selected from per second, per minute, and per hour.
Assume that a per-second flow rate is measured by a DX104. The summation of eight measured values
for each minute is calculated by simply integrating the measured values of the corresponding channel,
which produces a value eight times greater than the correct totalized flow rate since the measurement
period is 125 ms. Setting the scale to ”/s” (per second) will calculate the correct totalized rate based on
the measurement period.
The following shows an example of settings for DX104.
