start and stop a sample.

LOG Modes

There are three LOG modes: LOG 1, LOG 2, and LOG 3. When one of
these modes is selected using the SAMPLING MODE key, the LOG
mode number will be listed at the top of the display. The LOG modes
allow you to record aerosol concentration data points for later retrieval
and analysis using the software provided with the instrument.
Use the SAMPLE key to start and stop recording. The word
"RECORDING" appears at the top of the display when recording is in
progress.
The frequency that data is recorded can be set for LOG 1 mode with the
LOGGING INTERVAL key. Use T
LOG 3 modes.
Data recorded using one of the LOG modes can only be erased by using
the CLEAR MEMORY key. Turning the D
not erase data. Recording another sample with one of the LOG modes
without clearing memory first will cause new data to be added to the
existing data (using a new test ID).

CLEAR MEMORY Key

Use the CLEAR MEMORY key to erase all data. The CLEAR MEMORY
key will not respond unless the D
the three LOG modes by using the SAMPLING MODE key.
Note: Before clearing memory, you should first download the data to a
computer through the T
memory in the D
LOG mode clears memory for all LOG modes.
To clear memory, press and hold the CLEAR MEMORY key until the
countdown reaches zero, then release quickly. This prevents accidental
erasure of data. Releasing the key too soon or too late prevents memory
from being cleared.

LOGGING INTERVAL Key

Use the LOGGING INTERVAL key to view or set the frequency/averaging
period for recording data in LOG 1 mode or to view the current interval
setting in LOG 2 and LOG 3 mode. Use T
logging interval for LOG 2 and LOG 3 mode (see following section). The
LOGGING INTERVAL key will not respond unless the D
is first put into one of the three logging modes. Press the LOGGING
