ENERAL REMARKS
The bbe AlgaeTorch and bbe BenthoTorch are equipped with a GPS module that allows the user to determine
the position of each measurement. The position data are stored additionally with each dataset within the
instrument.
For data evaluation, the results can be read from the instruments display or transferred to the bbe++ PC
software. bbe++ offers an export of the data to Google Earth to display the chlorophyll results on a map.
The GPS module is made for outdoor operation. Within buildings, the satellite signals cannot be detected. For
this case, the GPS module can be deactivated.
Please note:
After starting the Algae- or BenthoTorch especially after a longer time or after transporting the instrument, it
takes some minutes to obtain the correct position.

EQUIRED QUALITY
(S

REQUIRED QUALITY
)
The quality of the GPS signal is so much the better the more satellites are available and the better the satellites
are distributed. The quality is calculated. The required quality is the quality of the GPS signal that leads to an
instant automatic start of the measurement. If the quality is insufficient, the GPS measurement can be skipped.
