INTRODUCTION
Congratulations on your selection of the Oregon Scientific
UVR 138 Ultra-Violet (UV) Sensor. This sensor records the
UV levels radiated by the sun and transmits that data to an
indoor weather station. When used together with a main
unit weather station, readings taken from this sensor can
provide information about UV trends and maximum sun
exposure times before the skin starts to burn.
This UV sensor is compatible with new Oregon Scientific
weather stations, such as:
• BAR998HG
• BAR321HG
In this box you will find:
• UVR138 remote Ultra Violet sensor
• User guide
•Wall mount
• Ground anchor
•4 UM-3 (AA) 1.5V alkaline batteries

GETTING STARTED
The UVR 138 records Ultra Violet light levels and then
transmits this data to a main (indoor) unit. It is splash proof
and should be placed in an area with maximum exposure
to the sun.
NOTE
The sensor range is up to 100 meters (328 feet)
with no obstructions, but if the main unit has a shorter range
than the sensor, you may have to move the sensor closer
for reception.
INSTALLING THE BATTERIES
1. Place remote unit as close as possible to the main
unit, no more than 100 meters (328 feet) away.
2. Unscrew the top of the sensor.
3. Remove the battery compartment covers.
4. Insert the batteries. Match the polarity, as shown on
the battery compartment.
5. Replace the battery compartment lid. Press RESET
and secure.

SET UP
(WALL MOUNT)
Use this fixture to attach the UV sensor to a vertical wall.
First make sure the surface is smooth and flat. Fix the mount
to the wall by inserting each of the four screws through the
screw holes on the flat surface of the mount and into the
wall. Make sure the LCD screen faces away from the wall.

GROUND ANCHOR
)
EN
Use this fixture to anchor the UV sensor into soft ground
e.g. soil or sand. For maximum safety, insert the anchor
into the ground slowly and carefully.

UVR138 English r8 10/15/03, 11:24 PM5

Position the sensor using the wall mount, table stand, or
ground anchor options. For best results:
• Place in a location with maximum exposure to
the sun.
• Place the sensor away from electrical or mechanical
objects.
• Place the sensor away from moisture.
• Do not place the sensor more than 100 meters
(
328 feet) from the main (indoor) unit.
• Position the sensor so that it faces the main (indoor
unit. Minimize obstructions such as doors, walls, and
furniture.
The sensor range is up to 100 meters (328 feet) with no
obstructions, but if the main unit has a shorter range than
the sensor, you may have to move the sensor closer for
reception. You may need to experiment with various
locations to get the best reception.
This icon will blink on the main unit UV value
display box when it searches for the sensor.
It stops blinking when the sensor has been found.
NOTE
Once the batteries are in place, the sensor will
transmit signals every 40 seconds. It will take over an hour
before all measurements on the main unit are displayed
(e.g. UVI history) because some measurements are hourly
averages.

RESET
The RESET button is located near the battery compartment.
Press it whenever you change the batteries, or whenever
performance is not behaving as expected (e.g., unable to
establish radio frequency link with the main unit). This will
return all settings to default values, and you will lose all
stored information.
BACKGROUND INFORMATION
NOTE
The following settings and information only apply
if you have an Oregon Scientific compatible weather station.
On the main unit weather station, UV readings are recorded
and interpreted in two areas of the display:
1. UV bar chart display.
2. The UV value display.
Based on readings transmitted from the sensor, the main
unit can calculate maximum sun exposure times before
the skin starts to burn. Each calculation can be customized
for a specific user (1-4). Calculations are updated every
time a new UV reading is received from the sensor. This
calculation is based on three factors:
• SKIN TYPE (user-selectable)
• SPF (user-selectable)
• UV DATA (collected by sensor)
SPF (Sun Protection Factor)
Individuals react differently to sun exposure. The SPF
indicates the level of protection needed when time is spent
under the sun. The selectable SPF range is between
1-50 and relates to how susceptible you are to getting
sunburn. Enter an SPF setting that corresponds to the SPF
protection you choose for your sunscreen products.
• 1-11 (low protection)
• 12-29 (moderate protection)
• 30-50 (high protection)
For example, if your skin is sensitive and you get sun burnt
easily, you will need a lot of protection from the sun’s UV
rays. In this case you should use a sunscreen with an SPF
rating of 30-50 for maximum safety, then input the
respective SPF in the main unit setting for accurate
calculation.

UV INDEX BAR CHART DISPLAY
The UV index bar chart shows ultra violet level patterns
taken over ten hours. Ultra violet level readings are taken
hourly, averaged, and then displayed as an index.
Measurements are displayed in 2-hour increments
(-10, -8, -6, -4, -2, 0).
For example, (-10) indicates the average hourly reading
taken ten hours ago, (0) is the most current average.
Readings will show approximately one hour after you setup
the sensor.
USER SETTINGS
Under the same exposure to the sun, individuals will react
differently. To account for this difference, settings can be
customized for up to 4 users. This way, information is
tailored to each individual for more accurate results. For
example, if there is a mum, dad, sister, and brother in a
house, you can assign a user number to each person such
as mum (1), dad (2), sister (3), and brother (4).
SETTING SKIN TYPE AND SPF
1. Press SELECT to choose UV mode.

and should serve only as a guideline. If UV levels reach
dangerous levels of 11 or higher, the index will start to flash.

CAUTION: UV exposure times are updated each time the
sensor transmits new readings to the main unit. Calculations
do not take into account how long you have already been
exposed to the sun, so it is important to note that the
displayed exposure times will not accurately reflect how
much longer you can stay under the sun if you have already
been exposed for some time.

VIEW CURRENT AND PAST UVI VALUES
Current and past UVI values can be recalled by pressing
the HISTORY button.
The number displayed in the top right box indicates the
time the UV index was taken. For example, the average
UV index recorded ten hours ago is indicated by a (-10),
the most current average is (0). The values monitored range
from (-10 to 0).
NOTE
If no keys are pressed within 10 seconds, the value
displayed will revert to the most current index (0).
