2.9 Datalogging
During datalogging, the MiniRAE 2000 Portable VOC
monitor flashes a superscript “L”, on the display to
indicate that datalogging is enabled. The monitor stores the
time stamp, sample number, and measured gas
concentration at the end of every sample period (when data
logging is enabled). In addition, the following information
are stored: user ID, site ID, serial number, last calibration
date, and alarm limits. All data are retained (even after the
unit is turned off) in non-volatile memory so that it can be
down loaded at a later time to a PC.
Datalogging event
When Datalogging is enabled, measurement readings are
being saved. These data are stored in “groups” or “events.
A new event is created and stored each time the monitor is
turned on, or a configuration parameter is changed, or
datalogging is interrupted (e.g. Communication with PC
during Hygiene mode). Information, such as start time,
user ID, site ID, gas name, serial number, last calibration
date, and alarm limits will be recorded.
Datalogging sample
After an event is recorded, the unit records a shorter form
of the data. This data contains: the sample number, time
(hour/minute) and gas concentration.
