ForMorePreciseMeasurements
To be able to conductmoreprecisemeasurements, itis necessary to minimize the factorsthatcontribute to
measurementerrors.There area greatvariety of sucherror-inductingfactors,which canbe linked to
machineerror and performance ofthe balance itself,as well asthe properties and condition of samplesbeing
measured, andthe measuringenvironment(e.g.,vibration,temperature/humidity).Thesefactors can readily
affect the results of measurement ona balancethat has resolutioncomparable to that oftheAJ Series.
Thismaterialincludessomeprecautionarynotesthat the usershouldbear in mind to eliminateerrorfactors
andensureaccuratemeasurementresults.

1.3 Drafts
1.4 Gravity
1.5 Electromagnetic
Waves
Try to maintainconstantroomtemperature as much as possible to prevent dew
condensation and unstableindications dueto fluctuations in temperature.
Lowrelativehumiditytends to inducestaticelectricity.(Relativehumidity of
about 60%is consideredideal.)
Themeasuringroomshouldpreferably be located onthe groundfloor orinthe
basement.Higherfloors are moresusceptible to heavyvibration and shaking,
whichmakesuchlocationslesssuitable for measurement. A roomfacing a
railway or roadwithheavytrafficshouldalso be avoided as much as practicable.
Avoidchoosing a locationsubject toa directdraft of airflowfrom anair-
conditioningunit or exposed to directsunlight,which may causeabrupt
fluctuations in temperature.
Alsoavoid a roomsubject toa heavyflow of people,sincefluctuations in drafts
andtemperature are likely to occur in such a location.
Thegravityacting ona samplevariesdepending onthe latitude or height ofthe
locationwheremeasurement is beingconducted. For thisreason, the same
sample may showdifferentweightindicationsfrom one place to another.
Therefore,make ita rule to calibrate the balanceeverytime itis relocated.
When the balance is locatednear an objectthatgeneratesintense
electromagneticwaves, itmaybe hinderedfromshowingaccurateweight dueto
theeffects of suchwaves.Therefore,avoidplacing the balance in such a
location.
Precautions onthe MeasuringBench
2.1Vibration/
Shaking
2.2Magnetism/
StaticElectricity
If the balance is subjected to vibrationduringmeasurement, its indicationswill
becomeunstable,thuspreventingaccuratemeasurementfrombeingconducted.
Toavoidthissituation,select a solidmeasuringbenchthat is lesssusceptible to
vibration. (A bench ina vibration-proofstructure orone made of concrete or
stoneworkwill be suitable.)Moreover, donot conductmeasurementwith a soft
cloth or paperplacedunder the balance,since the balance maybe rocked outof
itspreciselevelpositioning.
Place the measuringbench ina locationfreefromvibration as much as possible.
It isa goodidea to install the measuringbench ina corner ofthe measuringroom,
wherelessvibration is likely to occurthan inthe center ofthe room.
Avoidoperating the balance ona benchthat is susceptible tothe effects of
magnetism or staticelectricity.

Generallyspeaking,objectsmadeofsyntheticresinandglasshavehighelectric
