Explanation
Periodic Printout Interval
Periodic
Select the periodic printout interval mode.
Auto:
Automatically sets the printout interval in sync with the chart speed.
Manual: Set the printout interval manually.
Ref. Time
Sets the reference time for determining the times for executing the periodic printout.
The reference time is set in the range of 00 to 23 in 1 hour steps. Minutes cannot be
specified.
Interval
Select the interval from 10, 12, 15, 20, 30 minutes, 1, 2, 3, 4, 6, 8, 12, and 24 hours.
Mode
Sets the type of measured values to be printed.
Inst:
Prints the measured value at that point.
Report: Prints the report data over the interval. If Report is selected, set the type of
report data. Proceed to “Type of Report Data to Be Printed” below.
Off:
Disables periodic printout.
Types of Report Data to Be Printed
Mode
Sets the type of report data to be printed.
AVE: Prints the average value over the interval.
MIX:
Prints the minimum, maximum, and average values over the interval.
SUM: Prints the sum value over the interval. If SUM is selected, set the sum scale.
MIN: Prints the minimum value over the interval.
MAX: Prints the maximum value over the interval.
INST: Prints the instantaneous value.
SUM scale
Set this item only when SUM is selected.
SUM sums the data every computation interval. For flow values that have units /s, /min,
or /h, a simple summation results in the actual value not matching the computed result,
because the scan interval and the unit of the input values are different. In such cases,
set the sum scale to match the unit of the input value. In effect, the sum value with the
same unit as that of the input value is calculated.
For example, if the scan interval is 1 s, and the input value is 100 m
3
/min, a simple
summation would add 100 every 1 s resulting in 6000 after one minute. However, if the
sum scale is set to /min, then 1 s/60 s is multiplied every scan interval before the value is
added giving a result with an m
3
/min unit.
Off:
Simply sums the measured values.
/s:
Sums by converting the measured values to a value over 1 second.
/min: Sums by converting the measured values to a value over 1 minute.
/h:
Sums by converting the measured values to a value over 1 hour.
/day: Sums by converting the measured values to a value over 1 day.
