Computation/Report Function (Option)

For example, if the scan interval is 2 s, and the input value is 100 m
3
/min, a simple
summation would add 100 every 2 s resulting in 3000 after one minute. However, if the
sum unit is set to /min, then 2s/60s is multiplied every scan interval before the value is
added giving a result that is close to the actual input value. The scan interval unit is in
seconds.

If power is lost while the report function is in progress
If a power disruption occurred while the report function was in progress, the report
function will resume after the power is restored. The exact operation will vary depending

report measured/computed data up to the time of the power disruption are
used. For the next scheduled report, data after the power recovery
are used.
Before the time to create After power is restored, report data are created at the time of the
the report next normally scheduled report. All measured/computed data
excluding the power disruption period are used.

Status display
If the data of a measurement or a computation channel enter any of the conditions listed
below within the relevant time period (one hour for hourly reports and one day for daily
reports, for example), status “E” or “O” is output to the report. In addition, if a power
