4. Use ∧∨ keys to place cursor next to one of the following three methods of
storing test data:
Logging
ª Internal
PC
Both
Internal: Stores test data in the analyzer’s internal memory (over
1000 data sets can be saved).
PC: Sends test data out the analyzer’s RS232 port to a personal
computer. Before using this method, however, a personal computer
must be connected to the analyzer and configured to store received
data on its hard drive (refer to Section 2.11 Downloading Data to a
Personal Computer).
Both: Stores test data in the analyzer’s internal memory, and also
sends the test data out the analyzer’s RS232 port.
After choosing the logging method, press ENTER to make the selection
and display the Logging Interval screen.
5. The default interval (the time period between measurements) is
10 minutes. To change this value, use
∧∨ keys to select either 1, 5, 10, 15,
30 seconds, 1, 2, 5, 10, 15, 30 minutes, or 1 hour. Then press ENTER to
make the selection and display the Logging Duration screen.
Logging Interval
10 min
6. The logging duration is the length of time allocated to collecting data. Use
the
∧∨ keys to select either 1, 5, 10, 15, 30 minutes, 1, 2, 5, 10, 24, 48, or
72 hours. Then press ENTER to make the selection and display the
Logging Summary screen.
Note: The duration value can never be less than the interval.
Logging Duration
2 hr
7. The Logging Summary screen shows both the logging interval and
duration as chosen in Steps 5 and 6. For example: if the interval was set
to 10 minutes, and the duration set for 2 hours, then a combustion test
will be conducted every 10 minutes over a 2 hour period for a total of
12 readings. To change either the interval or duration value, press ESC
to abort the logging process and redisplay the first Logging screen.
