Introduction
GrayWolf Sensing Solutions provides a fully integrated system for measuring indoor
air quality and ventilation. A laptop computer (Lap PC) running WolfSense™ IAQ
LAP software takes readings of air quality from a probe connected through the serial
port. You may choose to view live readings as they happen, plot readings for a
selected measurement parameter in real time and/or log the readings for future use.
Later, you may use WolfSense™ PC software on the Lap PC to open files of logged
readings for printing, graphing or exporting to a word processor or spreadsheet.
In the DirectSense™ 100 kit, the probe (model IQ-410) has four sensors which
provide five measurements: Temperature (°F/°C), Relative Humidity (%RH), Dew
Point, Carbon Monoxide (CO), and Carbon Dioxide (CO2). The Dew Point is derived
from Temperature and Relative Humidity readings.
In the VentCal™ 100 kit, the probe (model CD-201) has two sensors which provide
measurements of Carbon Dioxide, Temperature, and Outdoor Air (OA) ventilation.
VentCal™ software (SOFT-VENT) upgrades the DirectSense™ 100 kit to include all
VentCal™ capabilities.
This manual will get you started. Help files are available in all WolfSense™ software.
Unpacking your GrayWolf Monitor
Figure 1 - Your GrayWolf monitor kit provides everything you need
to get started:
User Manual;
Probe: IQ-410 for DirectSense™ 100 or
CD-201 for VentCal™ 100 (see Figure 2);
ACC-A110 GrayWolf AC adapter (see Figure 2);
ACC-ADY-L9 serial/AC power adapter (see Figure 2);
PCC-05 probe pouch with shoulder strap (see Figure 56);
WolfSense™ software on CD-ROM (contact GrayWolf for
software on 3½” disks);
Fujitsu Lifebook computer (if ordered from GrayWolf) with
Lap-PC-manufacturer-suppliedaccessories.
NOTE: The VentCal™ software module is unlocked by a modified
serial number found on the CD case and may be installed only if
you have purchased this option from GrayWolf.

Powering
The Lap PC will run using its own battery pack or with the help of the AC adapter
supplied with the Lap PC. Before first use, charge the battery according to the
instructions in your Lap PC manual.
NOTE: Charge your Lap PC batteries frequently to avoid data loss.
Like the Lap PC, the probe runs on batteries or with an AC adapter. The probe uses
only alkaline batteries. The GrayWolf kit provides two D cells and a 110VAC adapter
(240VAC in Europe) for the probe. WolfSense IAQ LAP software will warn you if the
probe’s battery voltage is low. If, when you plug in the probe, its batteries are flat, you
will see “No Probe Attached” in the upper left-hand corner of the Lap PC screen.
Changing Batteries on the Probes
Hold the top of the probe with one hand and the handle with the other.
Twist the probe handle in a counterclockwise direction.
Remove the old batteries.
Insert 2 new D-cell alkaline batteries, ensuring that the battery positive is to
the top.
Carefully screw the handle back onto the probe, ensuring not to cross-thread
the handle or overtighten it.
When setting up the Lap PC to work only from a battery pack for an extended period
of time, refer to your Lap PC user manual for tips on conserving battery power. If the
Lap PC’s batteries become depleted, a warning message is issued and then
WolfSense IAQ LAP will automatically stop logging and suspend the Lap PC.
Figure 2 - Using an AC Adapter to Power the Probe
The ACC-ADY-L9 serial/AC power adapter allows you
to power the probe with an AC adapter if you will be
taking readings longer than the expected life of the
batteries. It has a serial adapter and an AC power
socket.

Setting up the Hardware and Software
The serial port on the Lap PC (as in Figure 2) is used to connect to the probe while
taking readings. Before attaching the probe, be sure the COM port is clear and that
the COM indicator appears in the lower right-hand side of the screen.
For most laptop PCs, you will use the mouse, touchpad or trackball to navigate in
WolfSense IAQ LAP. For the Fujitsu Lifebook, you may also use the stylus pen to tap
options on the screen. In this manual, you will see instructions to click on or tap an
option.
Complete the next 4 steps to install WolfSense IAQ LAP software.
1. Familiarize yourself with the Lap PC user manual and the Microsoft
Windows™ 98 manual.
2. Follow the instructions for setting up the Lap PC, including the manufacturer’s
recommendation for the number of hours to charge the battery pack before the
first use—even if powering it with the AC adapter provided.
3. Install the WolfSense software from the CD-ROM supplied in the kit:
If the CD doesn’t run automatically, from the PC Start menu,
run [drive]:\Setup.exe.
The Setup program loads WolfSense IAQ LAP and WolfSense PC onto your
Lap PC, and places two icons on the desktop.
4. Double-click or double-tap on the icon to start WolfSense IAQ LAP or WolfSense
PC. Use WolfSense IAQ LAP to collect readings from the probe and WolfSense
PC to analyzeand manipulate stored readings.

Details
Details allows you to display multiple measurement parameters in columnar format.
This section describes how to view in real time live readings which are updated at
two-second intervals (not user-adjustable). See “Stored Readings” on page 13 for
information on viewing data that has been logged into location files at user-selected
intervals.
To see continuously updated live values
from the probe, click on or tap the Details toolbar
button or View, Details.
The table displays columns based on parameters
chosen for display in View, Readings.
Statistics
The Statistics window displays the minimum, maximum and average readings for a
single parameter in a separate window that may be minimized and kept on the
screen.
The Manual/Auto button toggles between Automatic and Manual modes.
In Auto mode, readings taken from the probe at two-second intervals update the
minimum and maximum values, and are automatically added to the readings used to
calculate the average. The Stop/Resume button lets you stop and resume readings
in Auto mode.
In Manual mode, click on or tap Add to add readings manually to the tally of readings
included in the statistics calculations for the chosen parameter.
Clear resets the minimum, maximum and average to zero.
Click on or tap the Statistics toolbar button
or View, Statistics.
To choose a different parameter for display,
click on or tap the pull-down menu arrow.
Click on or tap the new parameter.
Click on or tap Minimize to shrink the window and
keep it on display.

Graph
Graph allows you to plot readings for a selected measurement parameter in real time
from Live Mode, Readings.
To see current values from the probe,
click on or tap View, Readings.
To choose the parameter you want to graph,
click on or tap the desired parameter.
Click on or tap View, Graph.
Click on or tap Options to change the appearance of
the graph:
Check Grid Lines to display gridlines;
Check Connect Points to draw lines between
points;
Set Update Time in seconds;
Set the number of Samples to be taken.
Data Organization: Sites and Locations
Logged readings are stored in individual data files called location (.loc) files.
Calibration data, text notes, drawing notes, and template reports are also stored and
organized as attachments to these location files (see “Notebook” on page 13).
Location files are stored in the Windows folder which WolfSense calls site folders or
Sites. WolfSense IAQ LAP and WolfSense PC software use the same Windows file
structure of site folders and location files on the Lap PC. If you create a location file
in WolfSense IAQ LAP, you will be able to open it from WolfSense PC.
Each site folder may contain multiple sub-sites and multiple location files to further
organize the data. For example, a site folder called "School" may have one sub-site
for the "Ground Floor" containing locations for the "Principals Office" and "Library"
and another sub-site called "3rd Floor" containing a location for the "Teachers
Lounge." The root site in the WolfSense file system is \My Documents\WolfSense\,
so the three location files would have these file names:
\My Documents\WolfSense\School\Ground Floor\Principals Office.loc
\My Documents\WolfSense\School\Ground Floor\Library.loc
\My Documents\WolfSense\School\3rd Floor\Teachers Lounge.loc
