Datalogging

TypesofDataRecording

ManualDatalogging:Manuallylogupto99readingsontoanSDcardviapush‐buttonpress.

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.

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.

7SDL730-en-GB_V1.0 12/16

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.

ManualDatalogging

InthemanualmodetheuserpressestheLOGbuttontomanuallylogareadingontotheSDcard.

AutomaticDatalogging

Inautomaticdataloggingmodethemetertakesandstoresareadingatauser‐specifiedsampling

rateontoanSDmemorycard.Themeterdefaultstoasamplingrateoftwoseconds.Tochange

thesamplingrate,refertotheSetupModesection(thesamplingratecannotbe‘0’for

automaticdatalogging):

1. SelectthesamplingrateintheSetupModetoavalueotherthanzero.

2. PressandholdtheLOGbuttonforatleast1.5seconds.Themeterwillflashthe

3. Ifacardisnotinsertedorifthecardisdefective,themeterwilldisplayEMPTYandexitthe

DATALOGGERmode.Inthiscase,switchthemeterOFFandtryagainwithavalidSDcard.

4. PausethedataloggerbypressingtheLOGbuttonmomentarily.TheDATALOGGERiconwill

stopflashingandthesampleratewilldisplayforashorttime.Toresumeloggingsimply

presstheLOGbuttonagainmomentarily.

5. ToterminatethedataloggingsessionpressandholdtheLOGbuttonforatleast1.5

PMA01.Upto99spreadsheetdocuments(eachwith30,000readings)canbestoredinthis

folder.

7. WhendataloggingbeginsanewspreadsheetdocumentnamedPMA01001.xlsiscreatedon

theSDcardinthePMA01folder.ThedatarecordedwillbeplacedinthePMA01001.xls

documentuntil30,000readingsarereached.

8. Ifthemeasurementsessionexceeds30,000readings,anewdocumentwillbecreated

(PMA01002.xls)whereanother30,000readingscanbestored.Thismethodcontinuesfor

upto99documents,afterwhichanotherfolderiscreated(PMA02)whereanother99

spreadsheetdocumentscanbestored.Thisprocesscontinuesinthissamefashionwith

Removethetwo(2)Phillipsscrewsfromtherearofthemeter(directlyabovethetopofthe

tiltstand).

Removeandsafelyplacethebatterycompartmentandscrewswheretheywillnotbe

damagedorlost.

Replacethesix(6)1.5V‘AA’batteriesobservingcorrectpolarity.

Replacethebatterycompartmentcoverwiththetwo(2)Phillipsscrews.



Neverdisposeofusedbatteriesorrechargeablebatteriesinhouseholdwaste.

Asconsumers,usersarelegallyrequiredtotakeusedbatteriestoappropriate
