, there are four
channels to select: CO
2
, Temp, rh, and CO.
Start Date
Start Time Enter the date and time to begin the sample:
•
If you enter a blank for a start date, the
sample begins whenever the specified start
time occurs.
•
If you enter a blank for the start time, both

While you are entering values for LOG 2 and LOG 3 modes, the
Percent Memory Required is dynamically updated to show the amount
of logger memory required to take the programmed sample. If the
protocol you have defined requires more than 100% of memory, you
can decrease the amount of memory required by manipulating the
following protocol parameters:
•
Increase the logging interval.
•
Decrease the length for the test.
•
Decrease the number of tests.
•
Decrease the number of channels.
The settings for each LOG mode must not require more than 100% of
the logger memory. Note also that if the
Percent memory required is
greater than the Available memory , the logging instrument
automatically stops the test when memory is full.
