transitionstothelogiclow).Therearebuilt‐inscaling
factorsyoucanselectforsupporteddevicesandsensors,
oryoucansetyourownscalingwhenyouselectrawpulse
counts.Youcanalsoadjustthemaximumpulsefrequency
andlockouttimeasnecessary.
State.Thisrecordshowlonganeventlastsbystoringthe
dateandtimewhenthestateofthesignalorswitch
changes(logicstatehightoloworlowtohigh).Thelogger
checkseverysecondforastatechange,butwillonly
recordatime‐stampedvaluewhenthestatechange
occurs.Onestatechangetothenextrepresentstheevent
duration.
Event.Thisrecordsthedateandtimewhenaconnected
relayswitchorlogiclowtransitionoccurs(thelogger
recordsaneventwhentheinputtransitionstothelogic

DeterminingLoggingDurationfor
Event/StateData
Thelogger’sstoragecapacityandloggingdurationvaries
dependingonseveralfactors,includinglogginginterval,number
ofchannelsconfigured,andthetypeofdatabeingrecorded.This
tableestimatestheloggingdurationbasedonrecordingeventor
statechangesononeinputchannelwithloggingsettostopwhen
thememoryisfull.Toestimateloggingdurationformultiple
eventorstatechannels,dividetheloggingdurationbythe
numberofactivechannels.Ifyouwanttoknowexactlyhowlong
theloggerwillrun,usepulseorruntimemodes.

Notes:
Typicalbatterylifeis1year.
Theloggercanrecordbatteryvoltagedatainanadditional
channel.Thisisdisabledbydefault.Recordingbattery
voltagereducesstoragecapacityandisgenerallynotused
exceptfortroubleshooting.
SettingMaximumPulseFrequency
Whenrecordingrawpulsecounts,theloggerdynamically
adjustsitsmemoryusagefrom4to32bitsinsteadofatypical
fixedwidth.Thisresultsintheabilitytostoremoredatausing
lessspace,whichinturnextendsloggingduration.Thedefault
pulserateis120Hz,whichisalsothemaximum.Youcanadjust
thisrateinHOBOware(seetheHOBOwareHelpfordetails).
Decreasingtheratewillincreaseloggingduration.The

MountingtheLogger
Therearethreewaystomounttheloggerusingthematerials
included:
ScrewtheloggertoasurfacewithaPhillips‐head
screwdriverandthefourmountingscrews,usingthe
followingdimensions.

Attachthetwomagnetstothebackoftheloggerand
thenplacetheloggeronamagneticsurface.
Usethehook‐and‐looptapetoaffixtheloggertoa
surface.
ProtectingtheLogger
Theloggerisdesignedforindooruseandcanbepermanently
damagedbycorrosionifitgetswet.Protectitfrom
condensation.Ifitgetswet,removethebatteryimmediately
anddrythecircuitboard.Itispossibletodrytheloggerwitha
hairdryerbeforereinstallingthebattery.Donotlettheboard
gettoohot.Youshouldbeabletocomfortablyholdtheboard
inyourhandwhiledryingit.
Note:Staticelectricitymaycausetheloggertostoplogging.
Theloggerhasbeentestedto4KV,butavoidelectrostatic
dischargebygroundingyourselftoprotectthelogger.Formore
information,searchfor“staticdischarge”intheFAQsectionon
onsetcomp.com.
BatteryInformation
TheloggerisshippedwithtwoAAalkalinebatteries.Youcan
alsouse1.5VAAlithiumbatterieswhendeployingtheloggerin
coldenvironments.Expectedbatterylifevariesbasedonthe
temperaturewheretheloggerisdeployedandthefrequency
(theloggingintervalandtherateofstatechangesand/or
events)atwhichtheloggerisrecordingdata.Anewbattery
typicallylastsoneyearwithloggingintervalsgreaterthanone
minuteandwhentheinputsignalsarenormallyopenorinthe
highlogicstate.Deploymentsinextremelycoldorhot
temperatures,loggingintervalsfasterthanoneminute,or
continuouslyclosedcontactsmayreducebatterylife.
TheloggercanalsobepoweredthroughtheUSBcable
connectedtothecomputer.Thisallowsyoutoreadoutthe
loggerwhentheremainingbatteryvoltageistoolowforitto
continuelogging.Connecttheloggertothecomputer,clickthe
Readoutbuttononthetoolbar,andsavethedataasprompted.
Replacethebatteriesbeforelaunchingtheloggeragain.
Toreplacethebatteries:
1.Disconnecttheloggerfromthecomputer.
2.UnscrewtheloggercaseusingaPhilips‐headscrewdriver.
3.Carefullyremovethetwobatteries.
4.InserttwonewAAbatteries(alkalineorlithium)observing
polarity.Whenbatteriesareinsertedcorrectly,allLEDsblink
briefly.
5.Carefullyrealigntheloggercaseandre‐fastenthescrews.
WARNING:Donotcutopen,incinerate,heatabove85°C
(185°F),orrechargethelithiumbatteries.Thebatteriesmay
explodeiftheloggerisexposedtoextremeheatorconditions
thatcoulddamageordestroythebatterycases.Donotdispose
oftheloggerorbatteriesinfire.Donotexposethecontentsof
thebatteriestowater.Disposeofthebatteriesaccordingto
localregulationsforlithiumbatteries.
HOBOwareprovidestheoptionofrecordingthecurrentbattery
voltageateachlogginginterval,whichisdisabledbydefault.
Recordingbatterylifeateachloggingintervaltakesupmemory
andthereforereducesloggingduration.Itisrecommendedyou
onlyrecordbatteryvoltagefordiagnosticpurposes.Evenwith
thechanneldisabled,abadbatteryeventwillstillberecorded.
