“DATE” Menu Item
The DATE menu item is used to specify the start date of the timer. The date must be entered
in the MMDDYY format. Leading zeros are required (For example, to sample on January 1,
2007, enter 010107).
TIME Menu Item
The TIME menu item is used to specify the start time of the timer. The time must be entered
in the HHMM format. Leading zeros are required (For example, to sample at 09:30 AM,
enter 0930).
DURATION Menu Item
The DURATION menu item is used to specify the length of time the unit should sample.
The duration must be entered in the HHMM format. Leading zeros are required (For
example, to sample for 1 hour, enter 0100). This is the intended length of the sample. Power
failures or other interruptions will not extend the sample time. For example, if the timer is
set to turn on at 12:00 and run for 24 hours, but the power fails for 2 hours. The timer will
stop at 12:00 the following day.
REPEAT Menu Item
The REPEAT menu item is used to specify the interval of time between sample start times.
If set to zero (NONE), the repeat feature is disabled and the timer will only execute once.
Several standard repeat intervals are selectable. For example, the “1 IN 3” selection will set
the repeat interval for sampling every third day (a new sample would start every 72 hours).
The CUSTOM selection allows for non-standard repeat intervals to be entered. When
entering non-standard repeat intervals, the HHMM format must be used. Leading zeros are
required (For example, to sample for 1 hour, enter 0100).
SAVE and EXIT Menu Item
The SAVE and EXIT menu item saves the current setup and returns to the Main Status
Display.
STOP and EXIT Menu Item
The STOP and EXIT menu item configures the timer so that it will not operate until it is
reprogrammed with valid parameters and returns to the Main Status Display.
