2.EnsuretheloggerisatroomtemperaturebeforeinsertingitintoaPCport.

3.Theexecutablefileforprogrammingisnamed“PDFLoggerConfigurationTool”.

4.Adataloggingsessioncannotstartuntilthedataloggerisproperlyconfigured.

ConfiguringtheTH30andRHT30foraDataloggingsession

Atanytimebeforeloggingisstarted,theloggercanbeprogrammedandre‐

programmed.Thepreviousloggingsessionwillbedeletedonceanewsessionis

started.

1. ConnectthedataloggertoaPCviatheUSBport.TheloggerwillswitchON

automatically.Notethatashortpressofthepowerbutton willalsopower

thelogger.

2. TheLEDwillglowgreenwhilea

connectionwithcomputerisbeing

established.

3. AnAutoPlaypromptwillappearonthePC

whencommunicationisestablished.

below.Refertotheearlierscreenshotofthe‘PDFLoggerConfigurationTool’

windowforreference:

DatalogSamplingRate

Selectthedataloggingsamplingrate(recordinginterval)from30seconds~

120minutes.Thedefaultsettingis30seconds.

DatalogStartDelay

Selectaperiodoftimethatmustelapsebeforerecordingcanbeginafterthe

Start/Stopbuttonispressed(selectfrom0minto24hours).Thedefault

settingis0minutes.

AlarmDelay

ThepresetalarmdelaytimefortheSingleEventAlarmmodeisalwayszero.

TheadjustabledelaytimerangefortheCumulativeAlarmis5~120minutes.

AlarmModes

SingleEventAlarmmode:TheLEDimmediatelystartsflashingredevery10

secondswhenthemeasuredvalueexceedsthealarmthreshold.

CumulativeAlarmmode:TheLEDbeginsflashingredonlyaftertheaverage

valueexceedsthealarmthresholdandalsoafteranyprogrammedAlarm

Delaytime.SeeAlarmDelayparameterabove.

AlarmDisable(default):Alarmfunctiondisabled.

AlarmNote:TheLEDwillcontinueflashingredevery10seconds(onceitis

triggeredbyanalarm)evenwhenthemeasurementlaterreturnstothe

normalrange.TostoptheLEDalarm,plugtheloggerintothePCUSBportto

generateareport,orpoweroffthelogger(shortpressofthepowerbutton

whileitisnotconnectedtothePC).

AlarmLimits

Selectthealarmthresholdrangesforairandexternalprobetemperature

(TH30)orairtemperatureandRH%(RHT30).Forexample,iftheexternal

probetemperaturerangeissetto2.0~8.0oC,whenthemeasurementfalls

below2oCorexceeds8oCtheLEDwillflashredevery10seconds.

Note:Ifanalarmoccursbetweentwologgingpoints,theloggeddatawillnot

showthealarmbuttheLEDmaystillflashredevery10seconds,especiallyin

SingleEventalarmmode.Ifdesired,usetheCumulativeAlarmmodeto

minimizethiseffect.

Password

A16alphanumericcharacter(max.)passwordmaybeusedtoprevent

unauthorizedre‐programming.

UserCompanyName

Inputacompanynametobeincludedonthelogreport(20charactersmax.).

ANoteOnTimeZones

TheloggerautomaticallysynchronizesthetimezonewiththeconnectedPC

when‘SAVE’isselected.Note:Timezonechangesoccurringduringloggingare

nottakenintoaccount.



Oncealltheprogrammingiscomplete,press‘SAVE’toconfirmthesettings.Closethe
