7.8 Setting the Periodic Printout Interval and the Type of Measured Values to Be Printed

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 m3/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 m3/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.
