Onset HOBO MX Series Quick Start

Quick Start for the HOBO® MX Water Level Logger (MX2001)
Before you begin: After completing steps 1–4, it is recommended that you perform a trial run of steps 5 through 12 before deploying the
logger.
IMPORTANT: When assembling the logger or attaching the cable, make sure the O-rings and mating housing surfaces are clear of any
debris. Any contamination of these surfaces can cause leaks that will lead to logger failure.
