10. BEFORE USING YOUR THERMOMETER
Beforeusingthethermometermakesureyouhavetheright
probeforthejob.Therearespecicprobesformeasuring
product,air,‘betweenpack’,surfaceanddeepfattemperatures.
Forpermanentinstallationthereisalsoachoiceof‘damped’
sensorsandfoodsimulants.
TheN9094iscompatiblewiththermistorandtypeTandK

rightprobeforthejob.
TheN9005iscompatiblewithallindustrystandardtypeTand
typeKprobeswithsub-miniatureconnectors.
BoththeN9005andtheN9094canbetestedusingaC9040
thermocouplesimulator.(C9040KtypeKsub-miniature,
C9040TMtypeTsub-miniatureandC9040TLtypeTLumberg).
Beforemeasuringproducttemperaturesmakesurethatthe
probeisadequatelycleaned.Usebactericidalwipes(PW175T
-Tubof175probewipesorPW70T-tubof70probewipes)or
immersetheshaftinasuitablefoodqualitysterilisingsolution.
Remembertoreadtheinstructionscarefullyandallowthe
speciedtime.
Thermometersneedtobecheckedatregularintervals
toconrmthattheiraccuracyiswithinspecication.Itis
recommendedthatthermometersareregularlychecked(every
threemonths).TheN9094canbecheckedbycomparingthe
measuredreadingwithacertiedtestcap.
ComarktestcapsallowyoutocheckN9094instrument
accuracyatspecicpointstoimproveyourcondencein
themeasurement.Thesecanbeusedonafrequentbasisif
required.
N9005andN9094thermometersandtheirprobescanalsobe
regularlycheckedusingmeltingice.Simplyuseabeakerfull
oficecubes,addcoldwaterandstirforafewminutes.Insert
thepenetrationprobeandstiritforafurthertwominutes.The
thermometershouldthenreadbetween–0.5°Cand+0.5°C.
Theaccuracycanbecheckedagainstareferencethermometer
suchastheKM20REF.Makesureyouusesufcienticecubes
