In-Situ Virtual HERMIT Tutorial - Manual (Page 6)

6 Software Overview
Today, the Virtual HERMIT software works with Level TROLL 700
instruments and the Rugged TROLL
® Net Hub to provide similar functionality
in a different set of tools (Figure 2):
• The Virtual HERMIT software provides the user interface via the laptop
computer.
• The Rugged TROLL Net Hub connects multiple Level TROLL 700
instruments to the laptop.
• The Level TROLL 700 instruments log the data.

Net Hub
In the configuration above, the Level TROLL instruments are connected to
the hub, which is connected to the laptop running Virtual HERMIT software.
The software provides logging configuration and control such as “stepping
the test”. Additionally, as the Level TROLL instruments log data, users can
view tabular and graphical water levels and drawdown in real-time.
1.2 ADVANTAGES OF THE VIRTUAL HERMIT AQUIFER TESTING KIT
1.2.1 Disconnecting the Laptop PC, TROLL Net Hub, and Cables During Recovery
One major advantage of the Virtual HERMIT kit is that previously, during the
recovery phase, the old-style HERMIT loggers had to remain in the field
connected to the pressure transducers. Now, during the aquifer recovery
phase, the cables, Rugged TROLL Net Hub, and laptop can be taken out of
the field. The Level TROLL instruments can be locked inside the well caps
and can continue to log data. The recovery data can later be downloaded
well-by-well using a RuggedReader
® handheld PC, and Win-Situ ® Mobile
software or by reconnecting the instruments to the TROLL Net Hub and PC
