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 55)), 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).
If the external integration reset is not performed after the time of the ongoing
integration end + the waiting time for integration reset (3 min for the standard
specification, 6 min for special specification):
The integration result will be recorded at that time and then the integration value output will be
reset to zero (integration reset). The internal clock will not be adjusted.
If the internal clock is put back:
The subsequent operation depends upon the corrected time.
If the corrected time is the same as or later than the start time of the ongoing integration
calculation, the integration calculation will go on.
If the corrected time is earlier than the start time of the ongoing integration calculation, the
integration results up to now will be discarded and new integration calculation will start.
If the data that now being saved and an existing data have the same creation time:
The existing data will be overwritten with the new one (the existing data will be deleted).
If an existing data has the creation time later than that of the data now being saved:
The data having the later creation time will be deleted.
