OPERATION OF THE AREARAE
2-25
2.10 Datalogging
The AreaRAE calculates and stores gas readings based on the
user-specified datalogging period and type of measurement.
Two types of gas measurements, average or peak concen-
tration may be stored for each sensor for any datalogging
interval. Datalogging intervals may be programmed from 1
second to 60 minutes in 1-second increments. In addition, time
stamp, user ID, site ID, serial number, last calibration date, and
alarm limits are also stored. Since all data is retained in non-
volatile memory, The user may download information to their
PC at a later time.
Datalog Options
Most of the datalogging options may be programmed from the
monitor. When the monitor is connected to a PC, additional
options may be programmed and then downloaded to the
monitor. There are four options to select from:
1. Automatic: automatically starts and stops datalogging
when the monitor is turned on and off, respectively.
2. Manual: You manually start and stop datalogging. You may
also set the timer for datalog run times.
3. Periodic: datalogging is scheduled on a daily basis with a
preset parameter in hours and minutes.
4. Schedule: datalogging is scheduled for a preset date
(month/day) and time (hour/minute).
