Model BA888
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 issues that may arise due to wrong
forecasting with this unit.

DESCRIPTION OF PARTS
INSTALLING AND REPLACING
BATTERIES
The unit uses four UM-4 ‘ AAA’ size batteries. If the

DISPLAY AND FUNCTIONS
3. Insert the batteries as indicated by the polarity
symbols ( + and - ) marked inside the battery
compartment.
4. 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.
f, Clock time shows AM12:00.
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‘ means the past pressure was higher than the
present pressure by 2 mb.
This gives you the pressure trend over the last 24 hours.
The weather will be getting better ( worse ) if this chart
shows the bar marks moving up ( down ) towards the
present time ‘ 0H ‘.
BAR GRAPH PRESSURE TREND
Important:
It is only possible to measure the barometric pressure trend
properly if your barometer remains at the same altitude.
When moving around at different altitudes within a short
time period, the air pressure changes, the barometric pressure
change is not correct until the barometer has remained at a
constant altitude for 24 hours.
