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.
