OBS-3A Turbidity and Temperature Monitoring System
FIGURE 6-2. Battery installation
For extended deployment time, lithium batteries are a good alternative to
alkaline batteries. Campbell Scientific sells a D-cell-sized battery spacer
(pn 21906) that allows lithium D-cell batteries to be used with the OBS-3A.
Lithium D-cell batteries have a higher voltage than their alkaline counterparts,
necessitating the spacer. Campbell Scientific does not sell lithium D-cell
batteries.
6.2 Software Installation
Install HydroSci before connecting the OBS-3A to the computer. NOTE
Insert the ResourceDVD and type “OBS-3A” in the product window. Install
the HydroSci software. Follow the installation wizard to install the software.
This utility is your interface with the OBS-3A. As part of the installation, a
system-maintenance program is included. Communication drivers exist on the
CD.
The main purpose of this section is to explain how to program and operate the
OBS-3A with HydroSci. It covers: 1) turning the OBS-3A ON and testing the
sensors, 2) setting it up to sample in one of its four modes, 3) recording data
with a PC or uploading data from the OBS-3A, 4) importing data into a
spreadsheet, 5) plotting data, and 6) turning the OBS-3A OFF.
