485 = (0/100/100/10)
123 = (0/18/100/0)
Notes:
How it Works
This.REED.Infrared.Thermometer.measures.the.surface.temperature.of.an.
object. The unit’s optics sense emitted, reflected, and transmitted energy,
which.is.collected.and.focused.onto.a.detector..The.unit’s.electronics.
translate.the.information.into.a.temperature.reading.which.is.displayed.on.
the.unit..In.units.with.a.laser,.the.laser.is.used.for.aiming.purposes.only.
Field of View
Make.sure.that.the.target.is.larger.than.the.unit’s.spot.size..The.smaller.
the.target,.the.closer.you.should.be.to.it..When.accuracy.is.critical,.make.
sure.the.target.is.at.least.twice.as.large.as.the.spot.size.
Distance & Spot Size
As.the.distance.(D).from.the.object.increases,.the.spot.size.(S).of.the.area.
measured.by.the.unit.becomes.larger..See.Graphic.on.Page.4.
Locating a Hot Spot
To find a hot spot aim the thermometer outside the area of interest, then
scan.across.with.an.up.and.down.motion.until.you.locate.hot.spot.
Reminders
1..Not.recommended.for.use.in.measuring.shiny.or.polished.metal.
. surfaces.(stainless.steel,.aluminum,.etc.)..See.Emissivity.
2..The.unit.cannot.measure.through.transparent.surfaces.such.as.
. glass..It.will.measure.the.surface.temperature.of.the.glass.instead.
3..Steam,.dust,.smoke,.etc.,.can.prevent.accurate.measurement..
. by.obstructing.the.unit’s.optics.
Emissivity
Emissivity.is.a.term.used.to.describe.the.energy-emitting.characteristics.of.
materials..Most.(90%.of.typical.applications).organic.materials.and.painted.or.
oxidized.surfaces.have.an.emissivity.of.0.95.(pre-set.in.the.unit)..Inaccurate.
readings.will.result.from.measuring.shiny.or.polished.metal.surfaces..To.com-
pensate, cover the surface to be measured with masking tape or flat black
paint..Allow.time.for.the.tape.to.reach.the.same.temperature.as.the.material.
underneath.it..Measure.the.temperature.of.the.tape.or.painted.surface.
