thesamplingrate,refertotheSetupModesection(thesamplingratecannotbe‘0’for
automaticdatalogging):
1. PressRECbuttontoturnonrecordmode.
TheRECiconwillappearintheupperleftcorner

2. StartanautomaticDataloggingsessionbypressingtheLOGGERbutton.
3. ThemeterwillscanforanSDcardandverifythatitcanbeusedtostoredata.Ifacardis
notinsertedorifthecardisdefe
ctive,themeterwilldisplaySCANSDindefinitely.Inthis
case,switchthemeterOFFandtryagainwithavalidSDcard.
4. IftheSDcardisvalid,thedisplaywillshowtheDATALOGGERiconandthenthe
DATALOGGERandtheRECiconswillflasheac
htimethatareadingisstored.
5. TopausethedataloggerpresstheLOGGERbuttonmomentarily.TheDATALOGGERandREC
iconswillstopflashing.ToresumeloggingsimplypresstheLOGGERbuttonagain
momentarily.
6. ToterminatethedataloggingsessionpresstheLOGGERbuttontostopthelo
ggingandthen
presstheRECbuttonforatleast1.5seconds.
7. WhenanSDcardisusedforthefirsttimeafolderiscreatedonthecardandnamed
TMD01.Upto99spreadsheetdocuments(eachwith30,000readings)canbestoredinthis
folder.
8. Whendataloggingbe
ginsanewspreadsheetdocumentnamedTMD01001.xlsiscreatedon
theSDcardintheTMD01folder. ThedatarecordedwillbeplacedintheTMD01001.xls
documentuntil30,000readingsarereached.
9. Ifthemeasurementsessionexceeds30,000readings,anewdocumentwillbecreate
d
(TMD01002.xls)whereanother30,000readingscanbestored.Thismethodcontinuesfor
upto99documents,afterwhichanotherfolderiscreated(TMD02)whereanother99
