Preface
Application
The Continuous Radon Monitor, Model 1027, is intended for use in indoor
applications of radon gas sampling. In a typical test the user locates the Model
1027 in the home to be monitored, connects power, and leaves the Model 1027
unattended for a period of two or more days. Ambient room air diffuses into the
Model 1027’s detection chamber. Radon decay by-products emit alpha particles
which are detected by the photodiode.
At the end of the monitoring period, the results are available in any of three forms:
numerical display on the control panel, printed report on the optional printer, or
computer display. Once data is downloaded to the computer, a report can be
printed using standard programs.
After obtaining report data, the memory can be cleared and a new test can begin.
The instrument is completely reusable and requires no supplies except power
and an optional backup battery.
The printer need not be present during testing. The Model 1027 can be moved
from the test site, and the report printed later. If multiple tests must be run
simultaneously, a single printer or computer can support many radon monitors.

3 Operation
Set Up
1 Unpack Model 1027 and place in position within space to be monitored for
radon gas. The device does not need to be level.
2 Avoid using switch-controlled outlets. Plug power adapter into power input
jack on Model 1027 (Figure 3-1), then plug power adapter into a mains power
wall outlet that matches power ratings printed on power supply.
Figure 3-1. Connecting Power to Model 1027
• Green POWER LED turns on.
• Yellow LED flashes twice followed by a single flash to indicate Model
1027 has performed all internal diagnostics and is functioning properly.
3 Insert TOP PANEL key and turn to ENABLE position to activate top panel
controls.
4 Press AVG but ton. If me mory is clear, thre e decimal points appear in display.
If memory is not clear, long term average radon concentration is displayed.
In this case, you must clear memory before collecting measurements.
CAUTION: Do not use in outdoor environments. Humidity and
extreme temperatures will cause measurement errors.
CAUTION: Clear memory before starting a new measurement. If
memory is not cleared, new measurements will be averaged with the
old measurements still in memory.
14
Clear Memory
1 Press and hold both buttons on top of Model 1027 until yellow LED turns on,
then release both buttons. Yellow LED flashes.
2 While yellow LED is flashing, press and hold CLEAR button. Yellow LED
initially turns off; then turns on solid, not flashing.
3 Release CLEAR button when yellow LED turns on solid.
4 When yellow LED and display LEDs flash, followed by a single flash of yellow
LED, memory is cleared.
Conduct Test
1 If desired, switch on backup battery. A fresh battery provides about 20 hours
of back-up operation.
2 Turn TOP PANEL switch to DISABLE, then remove key.
3 At end of monitoring period, insert TOP PANEL key and turn to ENABLE.
Display Results
1 Press AVG to display the average radon concentration in pCi/l over the total
monitoring period.
2 Press CUR to display the radon concentration in the current 12-hour period.
3 To print results, review Delayed Results below before proceeding to Reports
on page 17. Or, record results on a piece of paper for a handwritten report.
Note: When Model 1027 is powered on, a tamper sensor is always
active except for a 15-second period immediately following a CLEAR
memory procedure. To avoid a tamper notation on the first reading,
do not move Model 1027 once the tamper sensor is active.
Note: To test tamper sensor, CLEAR memory and conduct a test for
several hours. During the test, try lifting or sliding Model 1027. In the
printed results, a “T” should appear in the interval when the
disturbance was made.
Note: The AVG and CUR display values continue to update during the
entire test, even if the test period exceeds the maximum storage of
90 intervals. The interval storage stops updating after 90 intervals until
the next memory clear.
15
Delayed Results
Test results can be displayed, printed, or downloaded later or at another location,
provided you understand the following differences:
• When power is disconnected, the value of the latest partial interval and the
CUR value are lost from temporary memory.
• When power is on (including battery power) Model 1027 continues to
operate, providing values that are averaged into the result.
•If you take an AVG reading, disconnect power, restore power later and take
a second reading, the second AVG reading may be slightly different from the
first reading. This is because the first AVG reading includes the value for the
partial one hour interval in process. This partial value is stored in temporary
memory and is lost when power is disconnected.
This second AVG value is calculated using only completed intervals stored
in non-volatile memory.
Interpreting Results
The Model 1027 radon monitor is calibrated by setting internal switches to
determine the calibration J-factor, which provides the conversion between counts
per hour and pCi/L for that Model 1027. A separate calibration factor is also
calculated and printed on the calibration report.
The Model 1027 automatically multiplies the hourly measurements by the
J-factor to yield the actual pCi/L to within 5%, and then displays these results on
the printed report.
To improve accuracy, the user can manually multiply the measurement results by
the calibration factor that is listed on the calibration report for the Model 1027.
The measurement results on the printed report are calculated as follows:
• The hourly measurements are the number of counts recorded during that
hour, times the J-factor, rounded to the nearest 0.1 pCi/L.
• The Overall Average is the number of total counts, divided by the number of
hours, times the J-factor, then rounded to the nearest 0.1 pCi/L.
• The EPA Protocol Average is calculated the same as the Overall Average,
excluding the first four hours of measurements.
Note that the average of the displayed hourly measurements and the reported
averages may not be the same. This is due to differences in the rounding. As
described above, the displayed hourly measurements are rounded each hour,
while each average is only rounded once. The reported average is thus a more
accurate measurement than averaging the displayed hourly measurements.
If the EPA Protocol Average is close enough to the 4.0 pCi/L EPA threshold that
rounding is a possible issue, additional radon measurements should help to
determine the actual radon level.
16
Shutting Down
1 Unplug power adapter from mains power.
2 Switch off backup battery to avoid measurement interference with
completed test and to prevent battery depletion.
CAUTION: Switch off backup battery. When backup battery is on,
Model 1027 continues to operate.

Thermal Printer Maintenance
Rechargeable Battery Pack
The thermal printer’s battery pack (P/N 750052) allows report printing without AC
power. The battery pack is automatically recharged when AC power is connected.
Charging Battery Pack
1
Turn power off.
2 Connect AC adapter to printer. POWER light flashes once every second while
battery is charging. It takes about 10 hours to completely recharge.
3 When POWER light stops flashing and turns off, battery is fully charged.
Disconnect AC adapter.
Inserting Battery Pack
1
Turn printer over and slide battery cover away from battery pack enclosure.
See Figure 5-2 on page 23.
2 Connect battery pack connector to printer connector.
3 Turn battery pack so label is visible, insert in printer, and close battery cover.

Figure 5-2. Inserting and Removing Battery Pack
Removing Battery Pack
1
Turn printer over and slide battery cover away from battery pack enclosure.
2 Pull out battery pack, grasp connector with thumb and index finger, and
disconnect battery pack.
3 Close battery cover.
Efficient Printer Battery Use
Battery efficiency decreases if the battery is recharged more than necessary.
Confirm whether POWER light is flashing and battery charge has decreased
before recharging battery.
When using the rechargeable battery, turn off the power switch after use. Leaving
the power switch on will consume battery and eventually run the battery down.
When using the AC adapter, note that the battery gradually recharges whether 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 when printing is completed. When not using the printer, turn off the
power switch and unplug the AC adapter.
Printer DIP Switch Settings
The thermal printer (P/N 850040(Z)) has internal DIP switches set by the
manufacturer. For proper operation, these switches must be set as shown (Figure
5-3). Check and, if necessary, set the switches as follows:
24
Figure 5-3. DIP Switch Settings for Printer
1 Slide power switch to OFF position (0), then slide power switch to ON posi-
tion (I) while pressing and holding ON LINE button.
2 Release ON LINE button after list of current DIP switch settings (Figure 5-3)
begins to print. When list of settings is complete, a prompt appears at the
bottom of the printout:
“Continue? : Push On-line SW”
“Write? : Push Paper feed SW”
3 To leave DIP switch settings the same, push FEED button.
4 To change any DIP switch settings, push ON LINE button. The prompt “Dip
SW-1” appears on the printout below the current settings.
25
5 Set each of the eight switches in DIP SW-1 by pressing either ON LINE for
”on” or FEED for ”off”. As each switch is set to ON or OFF, printer prints the
selection. When switch 8 is set, printer once again prompts with “Continue?”
or “Write.” Press ON LINE switch to “Continue to SW-2.”
6 In same manner, set DIP switches for SW-2 and SW-3.
7 When SW-3 is finished, press FEED to select “Write.” Changes are written to
printer memory, and printer returns to ON LINE mode.

Troubleshooting Data Download Issues
The steps in this section are for users who have already followed the procedures
in Using USB to Serial Adapter on page 8 and have 1) already connected a USB to
Serial adapter, 2) installed drivers for the adapter following the cable
manufacturer’s instructions, and 3) are still unable to download data from Model
1027 to the computer.
Typically, the inability to download data from Model 1027 is caused by the Com
port number assigned to the adapter. The Radon Monitor software only
recognizes Com ports 1 through 4, so if the cable uses Com port 5 or higher the
software will not recognize the cable. Perform this procedure to change the Com
port assignment to 4 or lower.
1 Turn Model 1027 OFF and exit Radon Monitor software.
Note: Vista 64-bit drivers are not supported by Radon Monitor.
Note: To use this procedure you may need to be logged in to the
computer as an administrator.
28
2 Open ‘Device Manager’ and in ‘Device Manager’ window, expand PORTS.
(For instructions see Verify Driver Installation on page 10.)
3 In Ports list, if using recommended IOGEAR USB to Serial Adapter look for
port labeled ATEN USB to Serial Bridge (com#). Look for something similar
to USB Serial Port (com#) if using a different USB to Serial Adapter cable.
4 Verify this is correct port by disconnecting and then reconnecting USB end
of cable from computer. Port should disappear from Ports list and then
reappear. If none of ports disappear and reappear with above test, computer
does not recognize USB to Serial Adapter. Reinstall drivers provided with
adapter and then try this procedure again. See Adapter Installation on page 9.
5 Double-click Port to open Com Port Properties.
6 Click Port Settings tab, then Advanced to display 'Advanced Settings’.
7 Click drop-down list with Com port number in it. Ports that are not available
are labeled “in use”.
8 Select available port 1, 2, 3, or 4.
9 Click OK to Com port selection then close Advanced Settings window.
10 In Com Port properties window, click OK.
11 Close all other windows opened using ’Device Manager’.
12 Return to Set COM Port in Radon Monitor Software procedure on page 12
and select the same Com Port number you selected in Step 7 of this
procedure.
Removing USB to Serial Adapter Drivers
To reinstall the drivers or to change to a different device, it may be possible to
remove the installed drivers via a software process. Refer to the manufacturer’s
instructions for details.
CAUTION: If ports 1 through 4 are labeled “in use”, all ports may be
assigned to a connected device OR to software for a device
(reserved for use when device is connected). Although it may be
possible to successfully connect via a port marked “in use”, this
might cause a device or software program to malfunction – proceed
at your own risk! Sun Nuclear is not responsible for any damage to
your computer as a result of selecting a com port labeled “in use”.

1 PRINTER PORT Port is for legacy printer (Model 020030), an accessory for early
Model 1027 radon monitors. Current printer connects to DATA
port.
2 DATA PORT RS-232 data port provides a way to transfer information from
Model 1027 to a laptop or personal computer. The information
transferred is identical to that sent through the printer port. (See
Set Up Communication on page 6.)
3 BATTERY
ON-OFF
Switch connects and disconnects the battery. When ON, the
battery powers Model 1027 whenever mains power is not
available. When OFF, the battery does not power Model 1027
when mains power is disconnected. Switch should be in the
OFF position when Model 1027 is not deployed for a test. This
is important for two reasons: first, battery life will be reduced,
and second, Model 1027 will continue acquiring measurements
as long as battery power is available, which could inadvertently
affect the results of a recent test. A fresh battery provides about
20 hours of backup power if mains power fails.
4 TOP PANEL-
ENABLE/
DISABLE
Key switch enables and disables digital display and buttons on
Model 1027 top panel. When in DISABLE position, Model
1027’s measurement performance is not affected. Model 1027
will function effectively in either key position. This feature is
designed to mitigate the temptation to tamper with a test.
5 DISPLAY 3-digit LED display. Three decimal points display when AVG or
CUR is pressed after memory is cleared.
6 pCi/l Picocuries per liter – the units of radon gas concentration shown
on the display.
7 AVG When pressed, the measured long-term average radon gas
concentration in pCi/l is displayed on the 3-digit display. This is
the cumulative average of the entire period since the memory
was last cleared. This value is not lost if the Model 1027 loses
all power.
8 CUR When pressed, the measured short-term radon gas
concentration is displayed. This is a rolling average of the most
recent 12 hours. This value is lost if the Model 1027 loses
power.
9 PRINT or
CLEAR
Function as PRINT and CLEAR buttons only when yellow LED is
flashing. To access this mode, hold both buttons down until
yellow LED turns on. Then release buttons, and yellow LED
begins to flash.
10 CLEAR Yellow LED must be flashing: When pressed, yellow LED turns
off. Hold down until yellow LED turns on again; then release.
Yellow LED and display LEDs flash once followed by a single
flash of yellow LED. Model 1027 memory is cleared.
Disturbance switch is inactive for the next 15 seconds.
11 PRINT Yellow LED must be flashing: When pressed, Model 1027
sends a report of the data contained in memory to PRINTER and
DATA ports. When button is pressed, yellow LED turns on.
When released, LED turns off and data transfer begins. When
data transfer is complete, yellow LED flashes once.
