Nøjagtighedskontrol

Hertil er en fri strækning på 20 m mellem to vægge (A og B) nødvendig, og der gennemføres en omslagsmåling ved vandret anvendelse via de to akser X og Y (4 målinger).

Laseren placeres vandret på et jævnt underlag eller på et nivelleret stativ i nærheden af den ene væg (A). Laserpunktet rettes i X-aksens retning mod den nærmeste væg (A). Efter nivelleringen markeres højden (strålens midte) på væggen. Derefter drejes apparatet 180°, nivelleres og strålemidten markeres på den anden væg

(B).

Nu placeres apparatet i nærheden af væg B. Det nivellerede apparats laserstråle rettes i X-aksens retning mod den nærmeste væg B, således at den forinden markerede højde (fra målingen på væg A) rammes nøjagtigt. Apparatet drejes 180°, nivelleres og strålemidten markeres på væggen A. Differencen (h) mellem de to markerede punkter udgør den faktiske apparatafvigelse.

Hvis apparatet ligger ved grænsen af fabriksnøjagtigheden (± 1,5 mm på 10 m) udgør den maksimale afvigelse fra nulpositionen 6 mm ved 20 + 20 = 40 m.

Dette skal gentages på samme måde for den negative X-akse og for den positive og negative Y-akse, således at højden fra alle fire retninger måles på det samme vægpunkt.

Apparatet opstilles til vandret anvendelse (f.eks. på stativ), således at laserstrålen er på den ønskede højde.

Derefter drejes prismet manuelt eller med rotationsfunktionerne til det ønskede målpunkt.
