Model BA-116

Electronic Barometer

Thank you for purchasing the Oregon Scientific barometer.
This barometer has been designed specificially with
performance and ease of use in mind. As with all Oregon
Scientific products, this barometer is made to the highest
quality standards using precision electronic components and
should give you many years of trouble free use.
Please read the User’s Guide carefully before use to ensure
you get the best out of your new barometer.

Please note that the accuracy of the weather forecasting is
about 70 ~ 75 percent, when monitoring changes in
barometric pressure alone, therefore, we cannot be held
responsible for any trouble which may come up due to a
wrong forecasting with this unit.

INSTALLING AND REPLACING

BATTERIES

The unit uses four UM-4 ‘ AAA’ size batteries. If the
‘BATT‘ indicator appears, removes the exhausted batteries
and follow these steps to install or replace the batteries:

1. Lift and pull up the top center edge of the battery
compartment cover, then remove the cover.

2. Insert the batteries as indicated by the polarity symbols
( + and - ) marked inside the battery compartment.

3. Replace the battery compartment cover.

Note: After replacing the batteries, the whole display
will be turned on for about 3 seconds and then
show the following:

a, Indoor temperature shows the current reading.
b, Indoor relative humidity shows the current reading.
c, Weather forecast shows slightly cloudy ( a sun shows

with the cloud indicator )

d, Pressure trend shows steady.
e, Barometric pressure shows the current reading.

The unit takes about 24 hours to store the barometric pres­sure data. Until that time has elapsed, the pressure trend and
weather forecast symbols may not reflect actual weather
forecast for your area.

HOW TO READ THE ILLUSTRATED

WEATHER FORECAST SYMBOLS

Your digital Barometer detects barometric pressure changes
and the LCD displays the illustrated weather symbols which
indicating the weather forecast for 12 to 24 hours ahead, for
an area with a radius of about 30-50 km.

Important:

1. The accuracy of weather forecasting when using
pressure trend alone is about 70 to 75 percent and,
therefore, we cannot be held responsible for any
inconveniences caused by an inaccurate weather
forecast.

2. The weather forecast symbols may not reflect the
current weather condition. The symbols are

forecasting the future.

3. A ‘ Sunny ‘ forecast covering the night-time reflects
fine clear weather.

HOW TO READ THE BAR GRAPH

PRESSURE TREND

Stored memory of the barometric pressure changes are
displayed on the chart, in 5 steps indicating the pressure
1,3,6,12 and 24 hours ago. This chart is plotted by comparing
the past barometric pressure to the present pressure. The
scale on the right shows the comparison result. The ‘ 0 ‘ in the
middle of the scale means equal to present pressure, ‘ +2 ‘
