After the battery was inserted the signal LED lights up for 2 seconds. This
means the logger has to be connected with the PC to set the date and time
(see section 8.3 S
ETTING THE PARAMETERS AND STARTING THE LOGGING JOB
and section 8.5 S IGNAL LED AND LOGGER KEY BUTTON ).
3.2 Mounting suspension
To attach the logger to a rope or chain, a suitable shackle is provided whose
bolt fits through the cross hole in the cap. As an alternative, you can screw
some different sling gear into the M6 threaded hole at the cap end (e.g. M6
eye bolt).
Corrosion
protection
In water, metal (e.g. zinc-plated) parts of the mounting suspension such as
thimbles, shackles or swivel connectors create voltages (chemically caused
according to the electrochemical series), which can cause corrosion of the
stainless steel of the logger or the above mentioned suspension parts.
Lightning
protection
Electrically conductive ropes or chains harbor the danger of the logger being
damaged by lightning.
Recommendation For reasons of corrosion and lightning protection, we recommend to use a
nonconductive suspension, e.g. one with low-wear, resistant polypropylene
ropes.
1 Unscrew the cap (Pos. 1 in Fig. 3-1).
2 Unscrew the sleeve (Pos. 2).
3 Insert the battery. When doing so, make sure that the battery is
correctly positioned (see label in the battery compartment).
4 Screw the sleeve on the shaft with the shorter thread. At the rear end
of the sleeve there is a thin O-ring inside (Pos. 3). Make sure that this
O-ring is evenly positioned in the groove and is not twisted.
5 Screw on the sleeve and cap again. In the screwed condition, no gap
may be visible at the joints.
