Important: Starting the WeatherStation
The
Weather

is
delinercdcalibrated
with
itsprogram
fileloaded.However,theWeather
Station
isshut downduringtrans'rtso
it willneedto be staftedagain.
This
can
be
donebefore
installation,
orwhilethesystem
isinstalledinthefield.Normally,
connecting
acomputer
willstart
theWeatherMaster,
indicatedby
a2-secondflash
rate.This requiresthat
thecomputer
systemis
setcorectly. If this
isnotpossible, astaft
plug
can
beusedtostafttheWeatherMaster.
Thefirststeptowards

your
WeatherMaster
willbe
tobecome

You
shouldbecome
familiarwiththe

immediately,
because
you
willneedtoconnect

3.4 Power System
TheWeatherMaster
2000
is
designedto be
aself-containedsystem requiring
verylittle
maintenance.
However,
it is
still
necessary
to understandsomeoftheissuesaffectingthebattery
lifeoftheweather station.
Thesolar
panel
on
theWeatherMaster2000should
provide
enough
power
to keep thesystem
charged
and
runningindefinitely.
Thisassumes
thatthe
solar
panel
will
not
be
in
the
shade,orin
overcast
conditions
formorethan2weeks atatime.
If the
WeatherMaster
2000is
to bestored
foraperiod
oftime
without
recording
data,
orifthe
system
is
to bedisconnected
fromitssolar
panel,
orstored
inadark
place,
it willbenecessary
to
place
thesystem
into
shutdown
mode.
Inthisstate alllogging stops
andthesystem
goes
intoalow
power
mode,
allowing
itto last
withoutsolar
power.
Select
the
"Shutdown
Logger"
menuoption
withthesoftware
supplied.Whentheprogram
indicates
thatshutdown
hasbeenachieved,checkthattheindicator
LEDonthesideofthe
WeatherMaster
hasstoppedflashing.
If theLEDhas
stopped
flashing,thecommunications
cable
can
bedisconnected
andthesystem can
bestored.
TheWeatherMaster
caneasilybe
re-startedandrefurnedto normaloperation
by
connecting
the
communicationscable
tothestaUonand,
using
theEasiAccess
program,
clickingonthebutton
to
connect
tothestation.
Wheninshutdown
mode,
the
system'sbatteryshould
lastabout
5months
withoutbeing
rechargedby
thesolar
panel.During
normal
operuffon,
it should lastabout
4weeks.
The
system
incorporates
anumber
ofspecial features
tro
reduce
itspower consumption.
However,
these
featuresbecome
ineffective
while
theloggeriscommunicating
withauser's
computer.
Thismeansthatthesystem's
power
consumption
increasesbyafactorof 10whilethe
user
isdownloading
data.
For
ftis reason,
it isadvisablenotto leaveacomputer connected
totheWeatherMaster
forlong
periods
ofUme,
unlessthis
is
absolutely
necessary.If acomputer
isleft
connected,
thetime
