Title: MAN 266, GTecLink Data loggers User Manual Check that power switch (SW A, Figure 3) is in the correct position. USB: the data logger is powered by the USB cable connected to any Android device or an external power source BATT (default): the data logger is powered by the batteries. -
Page 6: Safely Closing The Data 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). - Page 7 Title: MAN 266, GTecLink Data loggers User Manual ● A piece of rubber cord to seal the unused cable glands is provided in each box, cut as required. ● The antenna is mounted. If it is not, the antenna connector should be covered with a cap.
