Introduction
CongratulationsonyourpurchaseoftheRelativeHumidityandTemperatureDatalogger.This
dataloggermeasuresandstoresupto16,000relativehumidityand16,000temperaturereadings
over0to100%RHand‐40to+70°C(‐40to+158°F)measurementranges.Theusercaneasily
configuretheloggingrate,high/lowalarmandstart‐mode,anddownloadthestoreddataby
pluggingthemoduleintoaPC'sUSBportandrunningthesuppliedPCsoftware.RelativeHumidity,
TemperatureandDewPointdatacanthenbegraphed,printedandexportedtootherapplications.
GPP(grainsperpound)datacanbeviewedusingtheoptionalRHT10‐SWsoftware.Thedatalogger
issuppliedwithalong‐lifelithiumbattery,whichcantypicallyallowloggingforoneyear.Thismeter
isshippedfullytestedandcalibratedand,withproperuse,willprovideyearsofreliableservice.

BatteryReplacement

Itishighlyrecommendedthatthebatterybereplacedevery12months,orpriorto
loggingcriticaldata.


TheRHT10doesnotloseitsstoredreadingswhenthebatteryweakensorwhenthebatteryis
replaced;thedataloggingprocesswillhoweverbestoppedandcannotbere‐starteduntilthe
batteryhasbeenreplacedandtheloggeddatahasbeendownloadedtoPC.

Useonly3.6Vlithiumbatteries.Beforereplacingthebattery,removethedataloggerfromthePC.
Followdiagrammaticsteps1through4below.

NOTE:LeavingtheRHT10pluggedintothePCUSBportlongerthannecessarywillcausesomeof
thebatterycapacitytobelost.






WARNING:Handlelithiumbatteriescarefully,observewarningsonbatterycasing.Disposeofin
accordancewithlocalregulations.

Safety:Pleasedisposeofbatteriesresponsibly;neverdisposeofbatteriesinafire,batteriesmay
explodeorleak.Ifthemeterisnottobeusedfor60daysormore,removethebatteryandstore
separately.
