5.1 Timing Control Functions
108
Before starting integration and saving using timing control functions
• Before using automatic saving or integration, ensure that the real-time clock is correctly
set (p.129).
• The timing control cannot be set to CF card saving and integration independently.
• Integration is always active, so when a timing control function is active, appears on
the display. When timing control has stopped, press to reset integration and clear the
indicator.
• Even when a timing control function is enabled, you must press to begin operation.
About interval timing control
• If the timer or clock control is not active, integration automatically stops at 9999 hours, 59
minutes, and 59 seconds. In this case, press to reset the integration value and
restart integration.
• Interval timing is not available when the interval time setting is longer than the timer or
clock (start/stop) settings.
• When the ending time of the timer or clock settings is different from the ending time of the
last interval, the timer or clock setting has priority.
• When changing the interval setting, the number of recordable data items (p.143) also
changes (longer intervals allow more data items to be recorded).
About timer timing control
• When clock control settings define a time span longer than the timer setting, integration
starts at the specified clock start time, and stops when the timer setting has elapsed (any
clock control stop time is ignored).
• During integration and before the timer stops, pressing interrupts integration but
retains the integration value. In this case, pressing again resumes integration until
the timer stops ("additional integration").
About clock timing control
• When clock control is enabled for a time span longer than the timer setting, integration
begins at the specified clock start time, and stops when the timer setting has elapsed (any
clock control stop time is ignored).
• When the set time has elapsed, real-time control is considered disabled [OFF].
• When integration is interrupted during the clock control period, clock control is disabled
[OFF].
See the graph in "4.3.4 Integration Combined with Timing Control" (p.69) for integration
operations.
