1 INTRODUCTION
1.1 Overview
Thank you for purchasing the SPC-1 (Single Point Controller-1) monitoring
system The SPC-1 is the new interface method between a computer and
the PPM Technology range of hand-held instruments that enables the
discrete-time monitoring of hazardous formaldehyde Monitoring software
used together with its related hardware enables the SPC-1 to allow 8 PPM
Technology hand-held instruments to be automated when connected to
either the COM or USB ports of your PC Through using the SPC-1
programme it will be possible to list the available hand held instruments;
schedule the monitoring; collect and archive data; show graphical
representation of the data collected; set alarm threshold levels; and
generate graphs or reports from the stored data

2.1 Software Installation
Please place the CD into the CD-ROM drive and the software will
automatically run the installation program Clicking on to the “SPC-1 for
Windows XP / 2000” button to launch the installation wizard Using the
installation wizard, complete the installation by following the instructions
onscreen
If the auto run function on your computer is disabled, you can install the
software as follows:
1 From the Start Menu, Select Run
2 Type D:\INSTALL EXE (where D: is you CD-ROM drive)
3 Click on to the “SPC-1 for Windows XP / 2000”
4 Follow the instructions on screen
Your software is now installed To run the software, from the Start menu,
select Programs, PPM Technology and PPMonitor SPC-1 (if default settings
were used) Before running, the system will ask for a software activation
key Visiting htt ://www. m-technology.com/register.shtml can
generate your activation key
2.2 Running the Software
When running the software for the first time, please complete the Company

3.2 Log On / Log Off
The system is password protected and in order to start monitoring or
accessing the data, you need to Log On
The program is supplied with two users already created These are
Administrator (password: letmein) and Guest (password: password)
Access to all areas of the program is given to the Administrator, while the
Guest only has access to the monitoring and reports sections of the
program The Administrator, who can edit user privileges and passwords,
can also create more users
Figure 3.2.1 – Screenshot of the Login screen.
Once Log On is successful the button name changes to Log Off which can be
used to end the users session on the program The availability of some
features will depend on your privileges – if you do not have access then the
button will be grayed out

3.3 Monitoring Screen
By clicking the Monitor button, a list of available instruments (units) is shown This
list is common to several screens and will change automatically when units are
connected and disconnected An indicator is situated next to every unit on the list
The indicator shows the status of each unit The table below explains these:

Sampling
If a schedule is active then by selecting a particular unit, a graphical
representation of results from each of the sensors within that unit is shown, for
example when monitoring using a Formaldemeter
htV
the display will show
graphical representation of Formaldehyde, Temperature and Humidity
Formaldehyde is shown in ppm and mg/m³ A unit is selected by clicking on an
unit button, for instance Figure 3 3 1 is the result of clicking on the F 66 unit
button

3.3 Monitoring Screen
Figure 3.3.2 – A screenshot of the enlarged gra h in the monitor
screen.
By clicking on one of the small graphs in the monitor screen you are able to
view a zoomed version of this graph In Figure 3 3 2, the information at the
right hand side of the graph shows:
Current Schedule: The schedule start and end times are displayed when
scheduling is activated If schedule override is being used, then “n/a” is
displayed in these boxes
Current Axes Settings: These settings allow the user to adjust the values in
the y-axes By entering different values and pressing the Update button, the
graph will resize to the entered values To return to the default size, press
the Reset Ceiling button The values shown in these boxes are for the
primary y-axis That is “ppm” in this case
Graph Printing facility: This button allows you to print out the current graph
with some of the statistics shown under the Sensors tab The current graph
will be printed by the default printer and if no default printer is found then
this button will be disabled
Show all graphs: This button returns to the screen where the three smaller
graphs are shown for the unit

3.3 Monitoring Screen
Figure 3.3.3 – A screenshot of the enlarged gra h in the monitor
screen, sensors section.
By changing to the Sensors tab on the top right hand corner of the Monitor
screen more information about the readings is shown, these include:
Maximum, Minimum and Mean - When a graph is displayed, the highest,
lowest and mean values are displayed here Also shown is the recorded
time when the maximum reading was last taken The values shown in
these boxes are for the primary y-axis That is ppm in this case
Last Readings - These are the last readings collected by the software The
values shown in these boxes are for the primary y-axis That is ppm in this
case
Peak, T.W.A. and S.T.E.L. default values - These are alarm levels set for the
sensors Changes to these alarm levels can be made using the Setup
screen The values shown in these boxes are for the primary y-axis That is
ppm in this case

3.3 Monitoring Screen
Calculated T.W.A. and S.T.E.L. values - These are the calculated values for
Time Waited Average and Short Term Exposure Level based on the current
and previous readings The values shown in these boxes are for the
primary y-axis That is ppm in this case T W A and S T E L are industry
standard measurements for prolonged exposure to environmental
conditions
The T W A is used when both the chemical concentration and exposure
time varies It is usually calculated over 8 hours, which is the standard
daily work shift

S T E L is usually the average concentration for the last 15-minutes
mg/m³ values - These readings are currently only shown against the
Formaldehyde graph The mg/m³ calculation is based upon the
temperature when the reading was taken Because of this the mg/m³ axis
is only relevant for the last reading
