OPERATION OF AREARAE-Gamma

2.10 Datalogging
The AreaRAE-Gamma Multi-Gas Radiation Monitor calculates
and stores gas readings based on the user-specified
datalogging period and type of measurement. Two types of gas
measurements, average or peak concentration may be stored
for each sensor for any datalogging interval. Datalogging
intervals may be programmed from one second to sixty
minutes in one-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: user manually starts and stops datalogging. User
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).
