5 DATA PROCESSING

5.2 Integration
An integration data is calculated by dividing the measured values (momentary values)
acquired every 1 second by 3600 and summing these data for a specified calculation period.
This calculation result can be checked on the INTEGRATION screen.
The calculation period is 1 hour, and the data capacity is 1000 data.
Note

If the data counts exceeds the data capacity, the oldest data will be automatically deleted.

The time displayed on the INTEGRATION screen is the final data acquisition time.
Pressing the [INTEGRATION] on the MENU/DATA screen displays the screen showing the
latest data.

If an alarm occurs within the calculation period, the alarm record is also displayed with the
data.
Note

For the details of alarms, see “8.2 Alarm List” (page 83).

A maximum of 16 alarms can be displayed in high-priority order.
If the 17th or later alarms occur within the same calculation period, these alarms are not
displayed.
For the other screen functionalities, see “

Screens for data check” (page 31).

Integration calculation
In the case of the standard specification, the timing of the integration calculation start and end
is controlled by sending the ON signal to the integration value reset input (RST input) on the
signal connection terminal block (see “6.5.4 Integration reset setting” (page 57)), or by
receiving the integration calculation reset command via serial communication (refer to the
instruction manual of APXX-370 Series RS-232C).
These signal input and command reception are called external integration reset.
Once external integration reset is performed, the following action will occur automatically.
The internal clock time will be adjusted to the integration reset time nearest to the current time.
(For the standard specification, the default integration reset time is 00 min every hour. It can
be set to 30 min every hour.)
If the adjusted time is the same as the expected reset time of the ongoing integration, the inte-
gration result will be recorded at that time and then the integration value output will be reset to
zero (integration reset).
