2.4 Safely Closing the Data Logger
This is a very important step to ensure water tightness and
durability of the logger.
Close the cover by cross-screwing to the indicated torque 2.5 N.m.
The GTecLink family of data loggers have undergone water tightness
testing by an external laboratory and is rated IPX7 (1 meter for 30
minutes) and IPX8 for extended immersion (1 meter for 7 days).
To guarantee water tightness, you must be sure that:
●
The box is closed in a cross-shaped order after sensor
connection. All the screws must first be inserted and screwed in
until they are connected to the box and then adjusted using the
torque wrench. If these steps are not followed, the base faces and
cover may not be parallel, screwing may become more difficult
and the screw threads or the Helicoil inserts may be damaged.
Moreover, the joint (seal) may not be properly sealed and the
degree of protection against water intrusion (IP) could not be
guaranteed.

●
The box is screwed at 2 N.m (for single channel data loggers) o r
2.5 N.m (for multiple channel data loggers) using a torque
screwdriver (e.g. Ref. 1227107 from WERA).
●
The cable glands are closed with a 19 mm open e n d e d spanner
and the internal nut is held with a 22 mm open spanner.
