Field Deployment
Program the Instrument
In order to set up a log or download data, you must connect the instrument to a
computer running Win-Situ 5 Software, or a RuggedReader Handheld PC running Win-
Situ Mobile. See page 50.
Position the Instrument
Place the instrument at the desired depth. Position the instrument below the lowest
anticipated water level, but not so low that the pressure sensor range might be
exceeded at the highest anticipated water level. Refer to the tables below to determine
usable depth.
A BaroTROLL Instrument can be deployed with a non-vented
instrument to compensate level data for changes in atmospheric
pressure. Make sure the clocks on both instruments are
synchronized, and install the BaroTROLL in a location that will
never be submerged in water.
See page 39.
