1. Connecttheelectrodetotheprobeinputsocketatthebottomofthemeter.Immersethe
probeinthemeasurementsolution.
2. SwitchthemeterONbypressingthePOWER/ESCbutton.PressandholdtheFUNCTION
buttonuntiltheppmunitsaredisplayed.
3. Thelowerdisplayshowsthetemperature
value.
4. TheupperdisplayindicatestheTDSvalue(measuredinppm).
5. Holdtheelectrodeinhandandfullyimmersethesensingheadinthestandardsolution
6. Theupperdisplaywillshowtheppmvalueofthemeasuredsolution.Thebottomdisplay
willshowthetemperaturevalueof
themeasuredsolution.
7. Rinsetheprobewithdistilledwateraftereachuse.
8. PressandholdtheFUNCTIONbuttonforatleast2secondstoreturntotheconductivity
measurementmode.

MIN‐MAXDataRecording
Whenselected,theDataRecordingfunctionrecordstheMinandMaxreadings:
1. PresstheRECbuttononce.TheRECindicatorwillappearonthedisplay.PressRECbutton
onceagainandRECMAXwilldisplayonthescreenalongwiththemaximumvalue.
2. PressRECagainand thedisplay
willshowRECMINandtheminimumvaluewillbe
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
