The Inverse-square Law
The inverse-square law states that the illuminant E at a point on a surface
variesdirectlywiththeintensityIofapointsource,andinverselyasthesquare
ofthedistancedbetweenthesourceandthepoint.Ifthesurfaceatthepointis

Cosine Law
Thecosinelawstatesthattheilluminantonanysurfacevarieswiththecosine
oftheangleofincidence.Theangleofincidenceqistheanglebetweenthe

OPERATION
4.1 Recommendations Before Operating
• Keepthewhiteplasticdomedcosinecorrectorcleanandfreeofany
scratches.Itmaybecleanedwithasoftclothandalittlewateroriso-
propyl alcohol.
• Avoid reections or shadows from your body onto the sensor, when
lightisemittedfrommanydirections.
• Forbestaccuracy,repeatmeasurementsseveraltimestoensurethat
thelightsourceisstable.
• Avoidexingthecableexcessivelyateitherend.
4.2 Operating Instructions
1. Slidethefunctionswitchtothedesiredluxorfc(foot-candle)setting.
2. Selecttheappropriaterangeor,ifindoubt,selectthehighestsetting
(kluxorkfc).
3. Remove the sensor head cover.
4. Holdthesensorheadsteadyandmakesurethatthelightcompletely
llsthecosinecorrectionwhitedome.
5. Moveawayfromthesensorheadtoavoidshadowingit.Thesensor
headhasa5ft(1.5m)extensioncabletoallowseparationbetween
the case and the unobstructed measurement location.
6. PresstheRANGEbuttonuntilanoptimumreadingrangeisobtained.
7. Read the illuminant value directly from the display.
8. Whennished,slidethefunctionswitchtoOFFandcoverthesensor
head(extendsthesensorlife).
