Preface

What’s New

Software Changes

Version 2.2.0 of the radon monitor software interface includes the following new
features:

• Report Cover Page: A Create Cover Page checkbox has been added to the
print preferences. If this checkbox is selected, the report cover page will
include a selectable image and general information about the test site and
inspection company. For more information, see “Changing the Report (Print)
Preferences” on page 44.

• Report Shows if Mitigation System Installed: A Mitigation System
Installed checkbox has been added to the Print Preferences. If this checkbox
is selected, the printed report will indicate that a Radon mitigation system
was installed at the test site. The user can also display on the report whether
the mitigation system was working or not working at the time the test was
conducted. For additional information, see “Changing the Report (Print) Pref­erences” on page 44.

• Report Header Image: A Select Header Image option has been added to the
Print Preferences. If a header image is selected, it will appear at the top of
the first page of the report (not the cover page or other report pages). The
header can be aligned to the left, center, or right of the page. For more infor­mation, see “Changing the Report (Print) Preferences” on page 44.

• Report Images (Last Page and Cover): A Pictures tab has been added to the
main software screen. Up to six images can be selected for printing on the
last page of the report. If the cover page option is enabled, one of the images
can also be printed on the cover page of the report. For details about adding
images, see “Main Screen - Pictures Tab” on page 37.

• Report - Signature on First Page: If an image of the inspector’s signature is
selected, the user can also choose the Print Signature on First Page check­box in the Print Preferences to print the signature on both the first and last
pages of the report. For details about this option, see “Changing the Report
(Print) Preferences” on page 44.

• Report - Terminology Changes: In the report, the term “Elapsed Time” has
been changed to “Exposure Time” per EPA protocols. Also, % has been
added to the humidity label on the Model 1029 report page.

• Report - Page Numbers: Page numbers are now printed at the bottom of
each report page (except the cover page).

• Report - Time Display: The time is now displayed correctly in the printed
report (Hrs:mins).

v

• Report - Signature: The signature image is now correctly positioned in the
printed report.

• Report - Print Radon Information: The main software screen displays infor­mation about Radon Risk and how to understand time-sensitive testing
protocols. If desired, these information panels can be included in the printed
report. For details, see “Changing the Report (Print) Preferences” on page 44.

• Other Terminology Changes: The software screens and printed report now
display “Inspection Company” instead of “Inspector Info”.

• License Field Enhanced: The ‘License Number’ field now supports up to 100
characters. Multiple license numbers can be separated with any character,
such as comma, dash, colon, etc. For details, see “Changing Monitor Set­tings” on page 41.

• Chart Enhancements: The chart that is displayed on-screen and in the report
has been improved for easier reading.

• The chart title now includes the monitor model number and serial

number.

• The horizontal screen now displays the date in single-day increments

instead of the a date and time stamp to reduce clutter.

• The Action Level line (red, horizontal) is always displayed, even if the

maximum radiation count is less than the action level.

• The Action Level line can be hidden by deselecting a checkbox in the

chart legend panel.

• The chart now displays the overall overage (or EPA overall average)

above the legend panel as well as the words ‘Motion Detected’ if a
motion event is recorded in the chart. Additionally, if a Model 1029 is
connected, the chart will also display the Average Temperature, Average
Pressure, and Average Humidity above the legend panel.

• If a Model 1028 is connected, the chart will no longer show blank entries

for temperature, pressure or humidity. These values are only displayed
when a Model 1029 monitor is connected.

For details about these changes, see “Main Screen - Chart Tab” on page 35.

• Checklist: The software now provides a checklist that the inspector can use
to verify that best practice actions were completed prior to staring the test.
For details, see “Main Screen - Checklist Tab” on page 38.

• Retrieve Data from Text File: Data that is saved to a text file can be opened
directly from the software. When a text file is opened, the file data populates
the screen options and chart data. For details, see “Data to/from Text File” on
page 40.

• Site Address: The software now includes entries for both Billing Address
and Site Address. If the Billing Address is the same as the Site Address, the
information can be copied so the user does not have to retype the address.
The Site Address and Billing Address are both displayed in the printed report.
For details, see “Main Screen - Inspection Tab” on page 32.

vi

• Documents on CD: The CD that is distributed with the Radon Monitor now
includes three documents that the inspector can provide to the homeowner.
The main screen in the software lists the documents for easy reference. For
details, see “Main Screen - Inspection Tab” on page 32.

• Clear Screen button: The Clear Screen button in the software interface
clears all data that has been retrieved from the monitor and removes the pre­vious data from the screen. This provides a a visual cue for the user that all
existing data has been cleared and new data can be retrieved from the mon­itor. For additional information, see “Inspection Tab Details” on page 33.

• USB Drivers Installed Automatically: The software installation routine now
installs the USB drivers automatically. A separate driver installation proce­dure is no longer required. See “Installing Software” on page 29.

• Support for Windows 7 and 64-bit Operating Systems: The Radon Monitor
software can now be installed on computers that are running Windows 7 and
other Windows 64-bit operating systems. See “Computer/Software Require­ments” on page 29.

Introduction

Description

The Continuous Radon Monitor (Figure 1) is a patented detection device to
measure the concentration of radon gas. The unit is designed for professional
inspectors to use in homes and buildings.

Figure 1. Continuous Radon Monitors, Models 1028 and 1029

This guide covers both the Models 1028 and 1029. Model 1029 has greater
sensitivity plus temperature, pressure, and humidity sensors.

The radon monitor requires a standard 9V battery. It can be operated on an
alkaline battery alone for up to 100 hours or use an AC adaptor and use the battery
as a backup power source. A lithium-ion battery will provide about 300 hours of
operation.

A 16-character display shows instructions and radon readings. By pushing the
buttons below the display, the user can enter data, set parameters, and print
reports on an optional portable printer.

The radon monitor connects to a computer via a USB or serial cable. The
Windows software on the provided CD can be used to download measurements,
set parameters, and print reports on a printer connected to your computer. See
“Computer Operation” on page 29.

The Continuous radon monitor has been EPA verified and radon proficiency pro­grams approved.

1

Typical Application

In a typical test, place the radon monitor in a building or structure to be
monitored, connect power, and leave it unattended for the required test period.
Ambient room air, laden with radon, diffuses into the radon monitor’s detection
chambers. Gaps between the base and the cover allow air to freely pass into the
radon monitor. Radon decay by-products emit alpha particles which are detected
by the photo diodes and then counted. During a test, the number of counts
produced by the alpha particles is stored in memory and converted into radon
concentration (pCi/l) using the stored calibration factor.

At the end of the test period, the results can be viewed on the radon monitor
display, on the computer screen, or in a printed report.

After viewing or printing the report data, clear the memory. A new test cannot be
started until memory is cleared. The instrument is completely reusable and
requires no supplies except line power and/or a 9V battery.

The radon monitor can be moved from the test site, and the report printed later.

Figure 14. Typical Printer Report

23

Movement

The movement indicator (M) indicates if the unit was moved during the displayed
time period. The movement indicator is sensitive and can be triggered by
bumping or minor shifting. It could also mean that the unit was moved to a
different location during the test, invalidating the test.

Temperature, Humidity, Pressure

Model 1029 contains additional temperature, humidity, and pressure sensors.
Changes recorded by these sensors may help to determine if the unit was moved
or the area ventilated during the test period.

Printer Battery Pack

The rechargeable battery pack (P/N 750052) allows the user to print reports
without connecting the printer to AC power. The battery pack is automatically re­charged when AC power is connected to the printer.

Inserting the Battery Pack

1 Move the power switch to the OFF (0) position.

2 Turn the printer over and slide the battery cover away from the battery pack

enclosure (Figure 15).

Figure 15. Inserting and Removing the Battery Pack

3 Connect the battery pack wires to the connector.

4 Turn the battery pack so the label is visible, insert it in the printer, and close

the battery cover.

Removing the Battery Pack

1 Move the power switch to the OFF (0) position.

2 Turn the printer over and slide the battery cover away from the battery pack

enclosure.

24

3 Pull out the battery pack, grasp the connector between your thumb and index

finger, and then pull gently to remove.

4 Close the battery cover.

Charging the Battery Pack

1 Turn the power switch to the OFF (0) position.

2 Connect the AC adapter to the printer. The Power LED will blink once every

second while the battery is charging. It takes about 10 hours to completely
recharge the battery. When the battery is fully charged, the Power LED stops
blinking and turns off.

3 Disconnect the AC adapter.

Note: Always charge the battery in a location that is 5 to 40 °C (41 to
104 °F) to avoid degradation of the battery pack.

Low Printer Battery Indication

When the Power LED blinks once every 1/2 second and the printer goes into off
line mode, connect the AC adapter. If there is data left in the memory buffer when
this happens, connect the AC adapter as quickly as possible and push the
ONLINE button.

Efficient Use of Printer Battery

Battery efficiency decreases if the battery is recharged more than necessary.
Confirm whether the Power LED is blinking and battery charge is low before
recharging the battery.

When using the rechargeable battery, turn off the power switch after use. Leaving
the power switch on will consume battery power and eventually run the battery
down.

When the AC adapter is connected, please note that the battery gradually
recharges whether or not the printer is on or off. It takes about 15 hours to charge
the battery with the power on. Battery charging is temporarily disrupted while the
printer is printing and resumes automatically when printing is completed. If the
printer is not in use, move the power switch to the OFF position and then unplug
the AC adapter.

25

Storage

!

CAUTION: Always leave a good 9V battery in the unit to keep the
small internal battery from running down.

Store the radon monitor in an indoor, protected environment. Do not store the
radon monitor in the trunk of a car for extended periods. Keep the unit dry. For
long term storage, store in a cool, dry place and leave a 9V battery in the unit to
protect the internal battery. Periodically inspect the 9V battery and replace if
leakage or corrosion are found.

Cleaning

Clean the unit with a soft dry cloth. Do not use liquid cleaners, solvents, or
abrasives.

Disposing and Recycling

Do not discard unit as waste; the circuit board contains small amounts of lead.
Recycle the components in accordance with local regulations.

Battery Life

Any 9V battery will operate the radon monitor, but an alkaline battery (ANSI­1604A; IEC-6LR61) provides a good balance between long life and cost. Since
battery capacity varies widely between types of batteries and even between
individual batteries of the same type, the predicted battery life of 100 hours using
a fresh alkaline battery (or 300 hours using a fresh lithium-ion battery) is only an
estimate. An individual unit may have longer or shorter life.

Maintaining Software

The radon monitor has Windows software that is installed on a computer.
Although the distribution CD contained the latest released software version when
the unit was shipped, upgrades or patches may be available later. These changes
to the software add features, improve operation, fix problems, or adapt to
operating system changes.

These upgrades, when available, can be downloaded from the Sun Nuclear web
site, http://www.sunnuclear.com. Navigate to “Support,” then either “Download”
or “Software Upgrades.”

Verifying Software Version

The version of software may be verified as follows:

1 Launch the Radon Monitor application.

2 Connect to the radon monitor.

3 Select Help > About from the menu. The About Radon Monitor message

displays the version number of the Windows PC software.

52

Removing Software

!

To remove the radon monitor software from the computer, open the Control
Panel and then select Add or Remove Programs. In the list of programs, select
Radon Monitor and then click Remove. This will remove all of the radon monitor

program files.

Multiple Software Installations

Two or More Radon Monitor Units

The Radon Monitor software only needs to be installed on a computer one time,
regardless of the number of radon monitor units being used with that computer.

When connecting to a radon monitor, the software identifies the serial number of
the connected radon monitor and creates a unique serial number directory for
each radon monitor instrument. During measurement, the setup template
includes the serial number, which is validated against the radon monitor
instrument communicating data to the PC.

Two or More Computers

If you have more than one computer, the radon monitor software may be installed
on each one.

Service and Calibration

WARNING: The unit contains high-voltage circuits. Do not
open the case. There are no user-serviceable parts inside the
unit.

For service or calibration, return the unit to Sun Nuclear Corporation as instructed
in the Warranty statement on the inside back cover of the User’s Guide.

The manufacturer’s recommended calibration frequency for the model 1028 or
1029 radon monitor is one year. See your state or Proficiency listings for
requirements.

Optional Serial Connection

Connecting with a Serial Cable

If the computer does not have a USB port, the radon monitor can be connected
using a serial cable as follows:

1 Connect an optional serial cable between the computers 9-pin COM port and

the 9-pin PC PORT connector (Figure 31) on the radon monitor. For serial

53

cable part number, see “Accessories” on page 51. Serial cable can also be
used with optional printer.

2 If desired, plug the power supply into an AC outlet with 110 to 240 VAC,

single phase, 50-60 Hz.

Figure 31. Optional Serial Connection to a Computer

Serial Port Setup

Serial or USB port setup is automatic, unless there is a hardware conflict. When
the radon monitor software is launched and the monitor is plugged in, the
software automatically detects the unit on an available COM port. If the software
does not detect the radon monitor automatically, it may be necessary to select a
specific port.

Port Selection

Normally the software tries to connect to the radon monitor on COM 1. But if
COM 1 is in use, select another COM port as follows:

1 Click the Select Serial Port toolbar button or select Setup > Serial Port from

the menu. The ‘Setup Port’ dialog box opens.

Figure 32. Setup Port Dialog Box

54

2 Click the Ports drop-down list then select the desired port (usually the last

port in the list).

3 Click Save. When the program is opened again, the selected COM port will

be used.

System Errors

If an error message appears on the screen in the format “ERR=XX XX XX XX,” the
radon monitor experienced an unusual system error. Normally this indicates a
hardware or firmware failure. Make a note of the 8-digit error code.

Contact a Sun Nuclear Customer Support representative for assistance.

Note: Firmware version 0102 can cause a date error of 00 00 00 40
when attempting to print a report with a graph when no data is in the
