Chapter 5 Operating Functions
Three types of timing controls are available: interval, count-down timer, and real-time clock settings. Tim-
ing control can be applied to CF card saving and integration operations.

5.1 Timing Control Functions
Interval timing control Controls repeating operations at a specific interval.
Timer timing control
Controls operation for a specific count-down time. Combine with interval timing to
specify the duration of interval timing operation.
Real-time clock timing
control
Controls operation between specific real-time start and stop times. Combined with
interval timing to specify when interval timing operation begins and ends.
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. 101).
• 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. 112) 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. 59) for integration operations.
