OPERATION OF TOXIRAE
2 - 16
2.8 Datalogging
ToxiRAE Pocket PID Unit calculates and stores the gas
readings based on user specified data logging period and
the type of measurement. Three types of gas
measurements (minimum, average, and maximum
concentration) can be stored, at each datalogging period.
The datalogging period can be programmed from one
second to 60 minutes in one-second increments. In
addition, a time stamp, a user ID, a site number, serial
number, last calibration and check date, and alarm limits
are also stored. All data is retained in non-volatile memory
so it can be down loaded at a later time to a PC, even if the
unit was turned off.
There are several ways to initiate the datalogging
operation. The user can choose to start datalogging
automatically when the unit is turned on and off.
Datalogging can be manually started and stopped by
pressing a key. The user can further choose to start and
stop datalogging based on a preset time schedule.
All datalogging options and modes can be programmed
with a PC and down loaded to the unit.
