the LISST-AOBS to the SDI-12 logger. Sequoia Scientific can provide cable
pigtails for this purpose.

and receive. Typically these connections will be made to a computer
COM port, or a USB adapter, or to a data logger. The user must
determine to exact wiring depending on the mating device.
General Use and
Care
•
Do not use abrasives or harsh solvents for cleaning. These could
damage the plastic exterior.
•
Use special caution with the light-colored transducer disk on the
face of the LISST-ABS. Damage to the transducer can severely
affect accuracy.
•
Be sure water flows freely through the area directly in front of the
LISST-AOBS, and within 10 cm of the ABS face. Any solid object
within 10 cm can interfere with the measurements.
