Basic operating instructions
Introduction
This section of the manual covers the basic operation of RBR's submersible data
loggers: changing the battery, inspecting and replacing O-rings, etc. Please see
the
Software
section of this manual for instructions relating to logger
programming and data retrieval. This manual can also be found on the
distribution CD and on RBR's website (www.rbr-global.com).
Opening and closing the logger
1050 and 2050 series loggers
To open the TR-1050, DR-1050 or any of the 2050 family of
loggers, unscrew the sensor end counter-clockwise. The end
cap does not unscrew completely until the O-ring is clear of
its mating surface in the body. This ensures that it will not
eject at high speed should the interior of the logger become
pressurised.
Carefully draw the end cap away from the body, sliding the
attached inner assembly out of the case.
XR loggers
XR series loggers have two end caps: the sensor end cap
houses the sensors, and the battery end cap covers the data
port and battery carousel. Plastic loggers have a 6mm
mooring line hole through the battery end cap. Titanium
versions have a larger mooring line hole through a cylindrical
protrusion out of the battery end cap.
Access to the data port and the battery carousel is gained by
removing the end cap opposite the sensor end of the logger.
It may be unscrewed by hand or by using a rod inserted into
the mooring line hole for leverage. The end cap does not
unscrew completely until the O-ring is clear of its mating
surface in the body. This ensures that it will not eject at high
speed should the interior of the logger become pressurized.
Note:
Do not touch the circuit boards; moisture or even fingerprints
can affect the accuracy of the logger. The exposed logger should be
held by its sides.
