Thesampleratemustbesetto0toimplementthismode.
 AutomaticDatalogging:AutomaticallylogdataontoanSDmemorycardwherethenumber
ofdatapointsisvirtuallylimitedonlybythecardsize.Readingsareloggedataratespecified
bytheuserfrom1to3600seconds.
 RS‐232/USB:ThemeterincludesanRS‐232/USBPCinterfacejacklocatedonthelowerright
sideoft
hemeterunderthesnap‐offcompartmentcover.ForstreamingofdatatoaPCvia
theRS232Outputjack,theoptional407001‐USBkit(USBcableanddriverCD)alongwiththe

SDCardInformation
 InsertanSDcard(from1Gsizeupto16G)intotheSDcardslotatthebottomofthemeter.
Thecardmustbeinsertedwiththefrontofthecard(labelside)facingtowardtherearofthe
meter.
 IftheSDcardisbeingusedforthefirsttimeitisrecommendedthatthecardbeformatted
andthelogger’sclocksettoallowforaccuratedate/timestampingduringdatalogging
sessions.RefertotheSetupModesectionforSDcardformattingandtime/datesetting
instructions.
 EuropeanandUSAnumericalformatsdiffer.ThedataontheSDcardcanbeformattedfor
eitherformat.ThemeterdefaultstoUSAmodewhereadecimalpointisusedtoseparate
unitsfromtenths,i.e.20.00.TheEuropeanformatusesacomma,i.e.20,00.Tochangethis
setting,refertotheSetupModesection.
