Logger Hardware
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 Ruskin User
Guide 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.
