GettingStarted

1. Calibratetheinstrumentoften,asdescribedinalatersection.NotethatonlyapHcalibration

isrequired;mV(ORP)iscalibratedasaby‐productofthepHcalibration.

2. Settheunitofmeasureforsolutiontemperature(oCoroF)asdescribedintheTemperature

UnitsSelectionsectionofthisguide.

3. DetermineifAutomaticorManualtemperaturecompensationwillbeemployed.Referto

theTemperatureCompensationsectionofthisguidefordetails.

4. Followtheinstructionsandelectrodecleaning/rinsingrecommendationscloselyasslight

deviationsintestprocedurescanhaveasignificanteffectontestresults.

Calibration(pH)

CalibrationConsiderations

ThispHmeterwasfactorycalibratedbymVsignalssimulatinganidealpHElectrodeina25°C

(77°F)environment.Anidealelectrodewillproduce0.0mVatpHof7.00inidealconditions.

Electrodesareimperfecthoweverandthetemperatureatwhichtestsaretakenisnotalways

ideal.Tomaintainahighlevelofaccuracy,andtoaccommodateanygivenapplication,choosea

calibrationmethodfromtheselectionsbelow:



BasicCalibration(singlepointcalibration):pH7.00

CompleteCalibration(twopoints):pH7.00thenpH4.00orpH7.00thenpH10.00



Themetershouldbecalibratedoncepertestingsession.Calibrationisperformedusingstandard

buffersolutionsatroomtemperature25°C(77°F).Calibrationshouldalwaysbeperformedusing

thepH7.00bufferfirst,followedbyasecondcalibrationbufferifdesired.SelectthepH4.00

bufferforthesecondcalibrationiftypicalmeasurementswillbelowerthanpH7.00oruseapH

10.00bufferforthesecondcalibrationiftypicalmeasurementswillbegreaterthanpH7.00.If

thedisplayshows“ERR”,cleartheexistingcalibrationdataasdiscussedinthepHCalibration

Procedurebelow,andperformthecalibrationagain.



pHCalibrationProcedure

1. Placetheelectrodeinabuffersolution.PowerthemeterONandsimultaneouslypressand

releasetheRECandHOLDbuttons;‘CAL’appearsinthelowerleftcornerofthedisplay.

2. Usetheupanddownarrowbuttonstoscrollthroughthe4,7,and10calibrationpointsand

theClearfunction(CLr).OncethecorrectpointisselectedpresstheENTERbutton.The

readingwillflashforseveralsecondsandthenENDwillappear.Calibratetotheother

buffersinthesameway.

Note:Ifthereisadeviationofmorethan1pHunitfromthe4,7,or10pHbuffer,oriftheelectrode

slopeislow,theinstrumentwillassumeanerrorandabortthecalibration(ERRwillbedisplayed).In

thiscase,clearthecalibrationdata(seestep2above)andperformthecalibrationagain.Ifthe

problempersists,theelectrodemayrequirereplacing.

3. Formulti‐pointcalibration,usethearrowbuttonstoscrollthroughthecalibrationpointsas

describedinstep2.AlwayscalibratewithapH7bufferfirst,andthenfollowwithpH4or

pH10.Rinseelectrodeandprobewithdistilledwaterbetweencalibrationbuffers.

4. PressESCatanytimetoabortthecalibrationandreturntothenormaloperatingmode.

BatteryReplacement

The9Vbatterythatpowerstheinstrumentrequiresreplacingwhenthebatteryiconflasheson

thedisplay.Toreplacethebatteryfollowthestepsbelow:



1. Disconnecttheelectrode/probefromtheinstrument.

2. OpentherearbatterycompartmentusingascrewdrivertoremovethetwoPhillipshead

screwsthatsecurethecompartment.

3. Carefullyremovetheoldbatteryfromthecompartmentlidchamberandgentlyunsnap

thebattery’sterminalsfromthewired(red/black)connectors.

4. Installanew9Vbatterybysnappingthebatteryterminalsontothewiredconnectors

(observingcorrectpolarity)andinsertingthebatteryintothecompartmentlidchamber.

5. Installthecompartmentlidchamberintothemeterhousingandsecurewiththetwo

screws.



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

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

collectionsites,theretailstorewherethebatterieswerepurchased,orwherever

batteriesaresold.



Disposal:Donotdisposeofthisinstrumentinhouseholdwaste.Theuserisobligatedtotake

end‐of‐lifedevicestoadesignatedcollectionpointforthedisposalofelectricalandelectronic



ElectrodeMaintenanceandTroubleshooting

Mostmeasurementdifficultiesarecausedbytheelectrode.Carefulhandlingandproperstorageof

theelectrodewillincreasemeasurementaccuracyandelectrodelife.

Electrodesshouldberinsedoftentoremovealltracesofstoragesolution,processmedium,or

previoustestsolution.

ElectrodeStorage

TheelectrodeshouldbestoredinasoakerbottleorwettingcapfilledwithpH4buffer.Never

storeanelectrodeindistilledordeionizedwaterasthiswillcausemigrationofthefillsolution

fromtheelectrode.

ElectrodeCleaning

Thetypeofelectrodecoatingthatoccursovertimewilldeterminethecleaningmethod.Soft

coatingscanberemovedbyvigorousstirringorbyusingasquirtbottle.Organicchemical

coating(hardcoatings)shouldbechemicallyremoved.Onlyinextremecasesshouldthebulbbe

cleanedmechanically.
