Before you begin: Barometric pressure data at the site where the logger is being deployed is required for accurate water level data. Using a HOBO logger for recording barometric pressure data is recommended.
-

ttach the USB Optic Base Station (BASE-U-4) or HOBO Waterproof Shuttle (U-DTW-1) to a USB port on the computer (refer to the hardware manual at www.onsetcomp.com/resources for details).

a. Unscrew the black plastic end cap from the logger by turning it counter-clockwise.
b. Attach the coupler (COUPLER2-B) to the base station or shuttle.
c. Insert the logger into the coupler with the flat edge on the logger aligned with the arrow on the coupler label. Gently twist the logger to be sure that it is properly seated in the coupler (it should not turn). If you are using the HOBO Waterproof Shuttle, briefly press the coupler lever to put the shuttle into base station mode. It may take a few seconds for the new hardware to be detected by the computer
