SETTING UP PRESSURE MEASUREMENTS: THE PA-
RAMETER WIZARD
Win-Situ’s Parameter Wizard can help you configure a pressure chan-
nel to display measurements just as you want them. The specified set-
tings are easily changed from one mode to another, and any choice
can be redone or undone later, when viewing test data.
1. With the MP TROLL connected to a host PC and selected in the
Navigation tree, select the pressure parameter.
2. Click or tap Edit.... The Parameter Wizard starts. The choices are
discussed below.
3. When you finish the Wizard, Win-Situ sends the information to the
device and updates the display.
PRESSURE SETUP CHOICES
Win-Situ prompts for the following when editing a pressure channel.
You may not see all of these depending on your early choices.
1. NAME (OPTIONAL)
The pressure channel name is displayed in the Information pane and
in test data files. A default name is proposed. If you choose, you may
enter a custom name (up to 16 characters).
2. DISPLAY MODE

surface water elevations. Data file read-
ings are “positive up.” Increasing water
levels will result in increasing readings.
Decreasing water levels correspond to
decreasing readings.
s
used for drawdown in ground water wells.
This mode is “positive down.” Decreas-
ing water levels correspond to increasing
readings, because the water level is
getting further from the top of the well
casing. Increasing water levels result in
decreasing readings.
If you select depth or a level mode, you will be asked to choose a
method for converting pressure to depth or level. For a level mode,
you will be prompted to enter a level reference.
