pHCalibration(1,2,or3points)

Atwopointcalibrationwithabufferof7plus4or10(whicheverisnearesttotheexpected

samplevalue)isalwaysrecommended.Aonepointcalibration(choosethevalueclosesttothe

expectedsamplevalue)orathreepointcalibrationisalsovalid.Forbestaccuracy,always

calibrateatthesampletemperature.Frequencyofcalibrationisdependentonhowoftenthe

meterisused,thecareoftheelectrode,andstrengthofthesamplestested.Typically,itis

recommendedthatcalibrationbeperformedonceaday;orbeforeeachuseifthemeterisnot

usedonadailybasis.

1. ConnectthepHprobeandplaceitintoapH7buffer.

2. PressthePOWERbuttontoturnthemeteronandpresstheMODE/CALbuttonuntilthePH

iconappears.(Note:disabletheAutoPowerOfffeaturetoavoidanautomaticpoweroff

duringcalibration).

3. IftheMTCiconappearsnexttothetemperaturedisplay,pressthe▼or▲buttontoset

thetemperatureofthepHbuffer.Iftheoptionaltemperatureprobeisused,insertthe

probeintothebuffersolution.

4. PressandHOLDtheMODE/CALbuttonuntilthedisplaybeginstoflash‘7.00’.Themeter

automaticallyrecognizesthebufferandcalibratesitselftothatvalue.Attheendofthe

calibrationcycle,SAandEndwillbrieflyappearonthedisplayandthemeterwillreturnto

thenormaloperatingmode.

5. Whenacalibrationisperformed,thecalibrationicons(pH10)(pH7)(pH4)willbe

cleared(calibrationdataisnoterased)andwillbereplacedwhenasuccessfulcalibrationis

performedforeachbufferwithinonepoweroncycle.Theseiconsindicatewhatcalibration

levelswerelastperformed.Theydonotindicatehowrecentlythecalibrationwas

performedorifthecalibrationsarestillvalid.

6. RemovetheelectrodefromthepH7buffer,rinseinarinsesolutionandinsertitintothe

pH4orpH10buffersolution.

7. Repeatstep4forthesecondcalibrationpointandthenthethirdpointifdesired.

Note:Iftheoutputoftheelectrodefallsoutsidepredeterminedlimits,themeterwillcancelthe

calibration,indicateEnd,andflashtheRENEWicon.Thistypicallyhappenswhentheelectrode

hasagedandneedsreplacement.

Note:Toavoidcrosscontamination,alwaysrinsetheelectrodeinarinsesolution,likedistilled

water,whenchangingfromonebufferorsampletothenextbufferorsample.



ORPCalibration

TheORPelectrodedoesnotrequirecalibration.

However,youcantesttheORPprobe’saccuracyusinganORPstandard.

Conductivity(TDS&Salt)Calibration

Conductivityaccuracyverificationshouldbeperformedonaperiodicbasis;oncepermonthis

therecommendedcyclefornormaluse.Ifcalibrationisrequired,aconductivitystandard

solutionmustbeobtained.Themetercanbecalibratedinanyorallofthethreeranges.

Standardizingsolutionsof84µS/cm,1413µS/cmor12.88mS/cm(12,880µS/cm)areusedforthe

automaticcalibrationrecognitionprocedure.Noothercalibrationvaluesarepermitted.

Calibrationisalwaysdoneinconductivitymode.SincesalinityandTDSvaluesarecalculated

fromconductivityvalues,thisprocedurealsocalibratestheSalinityandTDSranges.

1. Fillasamplecupwiththestandardizingsolution.

2. TurnthemeterONandinserttheelectrodeintothesolution.Tapormovetheelectrodein

thesampletodislodgeanyairbubbles.

3. PressandholdtheMODE/CALbutton(approximately2seconds)untilthemaindisplay

startsflashing.

4. Themeterwillautomaticallyrecognizeandcalibratetothestandardizingsolution.Atthe

endofthecalibration,thedisplaywillbrieflyindicate“SA”,“End”andthenreturntothe

measurementmode.

Note:The“SA”willnotappearifthecalibrationfails.

5. The“rangecalibrated”alertwillappearinthedisplayforeachrangethatiscalibrated

duringthatpoweroncycle.

Lowrange,84µS/cm

Mediumrange,1413µS/cm

Highrange,12.88mS/cm(12,880µS/cm)

Note:Themeterallowsfora1,2or3pointcalibration.Ifcalibrationisdoneformorethanone

point,thelowestvaluestandardshouldbedonefirsttoobtainthebestaccuracy.



Temperature(pHandConductivity)OffsetCalibration

Thisprocedureallowsforerrorcorrectionoftheexternaltemperatureprobe(pH)orthe

conductivityprobe’sbuilt‐intemperaturesensor.

1. SwitchtopHorConductivity(Salt/TDS)mode.

2. Placethetemperatureprobeorconductivitycellinthesampleandallowthetemperature

readingtostabilize.

3. PressandholdtheUNIT/SETbuttonuntiltheºCorºFiconbeginsflashing.

4. Adjustthe▼or▲buttonstosetthedisplaytoindicatetheknowntemperatureofthe

sample.

5. MomentarilypresstheUNIT/SETbuttontosavethechangeandreturntothemeasurement

NotesonpHmeasurementsandelectrodes

1. TheElectrodeshouldbestoredinitswettingcapuntilused.UseapH4buffersolutionora

4.0MKCLsolution.

2. Ifbubblesareseeninthebulbarea,holdtheelectrodebyitscapandshakedownwards

untilbubblesareremoved.

3. Toimprovespeedofresponse,vigorouslystirtheelectrodeinthesample,buffer,orrinse

solution.

4. Afterexposuretoasample,buffer,orrinsesolution,shaketheelectrodewithasnap

motiontoremoveresidualdropsofsolution.

5. Whenpossible,usepartofthenextsample/buffertobemeasuredasarinsesolution,.

6. Keepbuffersandsamplesatthesametemperaturetoavoidtemperatureeffects.

7. pHreadingsstabilizefasterinsomesolutionsthanothers;allowtimetostabilize.

8. Electrodesdeteriorateovertime.Ifaccuracyfallsto10%theelectrodeshouldbecleaned.If

noimprovementisobserved,replacetheelectrode.

NotesontheConductivity/TDS/SaltCell

1. CellStorage:Onsheathedcells,replacethesheathoverthecellwhenstoring.Fornon‐

sheathedversions,soakthecelltipinde‐ionizedwaterforstorage.

2. CellCleaning:Aftereachuse,thecelltipshouldberinsedwithde‐ionizedwater.Ifsolids
