ConductivityCalibration
1. ConnecttheConductivityelectrodetotheinputsocketatthebottomofthemeter.
2. SwitchthemeterONbypressingthePOWER/ESCbutton.
3. PrepareaConductivityStandardSolution(forexample,1.413uS).
4. Holdtheprobebyitshandleandimmersethesensingelectrodecompletelyinthe
standardsolution.Shake/stirthesensingelectrodetoallowtheelectrode’sinternalair
bubblestoescapefromthesensingelectrode.
5. PresstheHOLDbuttonandthedisplaywillshowtheHOLDicon.
6. PresstheRECbuttonandtheupperdisplayareawillshowCALandthelowerdisplayarea
willshowYES.Toabortatthispoint,simplywaitandthemeterwillreverttothenormal
operatingmode.
7. Tocontinue,presstheENTERbuttonandthedisplaywillshowtheConductivityreading,
themeasurementunit,and,shortlyafter,theflashingCALicon.Notethatthemeterwill
showENDiftheelectrodedoesnotdetectanappropriatesolutionvalue.
8. WhiletheCALiconisflashingusethearrowbuttonstoadjustthedisplayedConductivity
readingtomatchtheConductivityvalueofthesolution.
9. AfterafewsecondsthemeterwilldisplayEND.Calibrationiscomplete.

displayed.
3. ToreleasetheheldMAXorMINreading,presstheHOLDbuttonwhileeithertheRECMAX
orRECMINiconsarevisible;nowonlytheRECiconwillbevisible.Themeterisnow
continuingtomonitorthehighest(MAX)andlowest(MIN)readingsbutisdisplayingreal
timemeasurements.ToviewtheMAXandMINvaluesagainusetheRECbuttonas
describedearlier.
4. ToexittheRecordmode,pressandholdtheRECbuttonforatleast2seconds.Thedisplay

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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
