Sinalnd Moisture Probe.
Model 6600
The performanceof this MoistureAnalyseris dependenton the correctuse and
instrumentcare by the customer.lt is importantto checkthe calibration(both
commodityand hardware)periodically
and, if necessary,make adjustments
followingthe procedurein this manual. The commoditycalibrationcan be
checkedby comparingthe MoistureAnalyserresultsagainstreferencesamples,
e.g. oven testedsamples(pleaseensurethat testedsamplesare basedon the
correctoven test specification).

The SinarrM
MoistureProbe,moisture Analyserhousesthe latestmoisture
measuringtechnologyin a compactpackage.lt has been designedto provide
fast moistureresultsusingwholegrainsamples.ln additionto % moisture
content,the MoistureProbealso measurestemperature.
Each instrumentis pre-calibrated
for up to seven commoditieseitherchosenfrom
package
programmes
a standard
of
or selectedfrom the SinarrMcalibration
library.The calibrationof any productcan be optimisedusinga biasfacility.
The SinarrMMoistureProbeis one of a familyof moistureanalysers.All models
have the facilityto transferand receivecalibrations
eitherfrom each other,via a
Sinar'MAcousticCouplerand telephonelinkor via the Internet.Similarlynew
commoditiescan be transferredor existingcalibrations
can be updatedwith new
information.
The SinarTM
MoistureProbehas been calibratedusingcleansamples. Accuracy
can be affectedby the presenceof stones,dirt, weeds, seeds,admixture,chaff
or otherforeignmatter.
Cleanthe sensorwith a soft brushto preventmaterialbuild-upon the fins.

BASIC PRINCIPLEOF OPERATION
The designconceptof the Sinar'MMoistureProbeis basedon the simultaneous
sensingof capacitanceand temperatureof the samplebeingtested,providinga
correctedmoisture(%) readingin a few seconds. lt worksaccuratelyon
productswith a moisturecontentrangingfrom approximately1o/oto 35%
dependingon the application.
The instrumentincorporates
2 sensors:
1.
Capacitance
The moisturein a sampleabsorbsthe electricalenergybetweenthe sensorfins.
The electricalsignalknownas "Capacitance"
increaseswith the moisturecontent
of the sample.
2.
TemperatureCorrection
The capacitanceof a sampleincreaseswith temperature.A temperaturesensing
thermistoris mountedin the samplecell and the microprocessor
carriesout an
automaticcorrection.
SinarrMrefer to a capacitancereadingcorrectedfor temperatureas a code 0

CHECKINGHARDWARECALIBRATIONS.
To checkthat the instrumentis in good workingorderthe sensors,(Temperature
and Capacitance)
shouldbe checkedas follows:
Temperature:
Pour the samplearoundthe sensorcoveringthe fins totally.Leavefor 30
secondsso that the sampleand sensortemperaturereachequilibrium.

Checkthe temperatureof grain using
an accuratethermometer.Switchon
the instrumentand pressTEMP. The two readingsshouldnot differby more
t h a n 1. 5 " C .
Capacitance:
This is checkedusinga €pacitance referencesample(code0 sample).Contact
your instrumentsupplierfor this sample.Pour the samplearoundthe sensor
coveringthe fins. Pressthe 0 buttonand then the%H20 button.The displayed
resultshouldbe no greaterthan 10.3 from the valueof the code 0 sample.The
code 0 value is writtenon the containerthe samplewas suppliedin.
lf any of these measurements
are out of tolerance,the instrumentshouldbe
recalibrated.
