14.7 ScaleCorrection
Useofscalecorrection
Byenteringascalecorrection,reductionsproportionaltodistancecanbetakenintoaccount.
• Atmosphericcorrection.
• Reductiontomeansealevel.
• Projectiondistortion.
Atmosphericcorrection
Thedistancedisplayediscorrectifthescalecorrectioninppm,mm/km,whichhasbeen
enteredcorrespondstotheatmosphericconditionsprevailingatthetimeofthemeasurement.
Theatmosphericcorrectionincludes:
• Adjustmentsforairpressure
• Airtemperature
Forhighestprecisiondistancemeasurements,theatmosphericcorrectionshouldbedeter‐
minedwith:
• Anaccuracyof1 ppm
• Airtemperatureto1°C
• Airpressureto3 mbar
Type Protection

Type Protection
Zoominstrument Max95%noncondensing.
Theeffectsofcondensationaretobeeffectivelycounteractedbyperi‐
odicallydryingouttheinstrument.
