SECTION 2 OPERATION OF MINIRAE PLUS
2 - 15
2.8 Datalogging
The MiniRAE Plus Professional PID Unit is capable of
recording crucial data during normal operation. The recorded
data can be down loaded to Personal Computer later on for
record keeping or report generation. The data recorded in two
operating modes are different:
Hygiene Mode:
In Hygiene Mode, MiniRAE Plus Professional PID Unit
calculates and stores the values of TWA, STEL, Peak
concentration and 12 hours of STEL readings taken at 15
minutes interval ( a total of 51 readings). In addition, the time
stamps which indicate: when the unit was last turned on and off,
when the peak occurred and when the TWA alarm occurred (if
any) will also be recorded.
In Hygiene Mode, the datalogging operation is activated
automatically when the unit is turned on. When power is turned
off, the data will be retained in non-volatile memory. At each
"turn on" time, the previously stored data will not be cleared and
the unit will continue to record data. If users wish to clear the
data at power on, they need to follow the special power on
sequence as described in section 2.11.
When the data memory is full (12 hours of STEL readings), the
unit will stop recording new data and the previously stored data
will not be over written.
