Laser Accuracy and Repeatability

The accuracy and repeatability of a laser transmitter are measured
in arc seconds. Arc seconds is an angle of measurement used when
specifying the accuracy of a laser or other leveling instrument.

A circle is divided into 360°. A degree is divided into 60 arc
minutes. An arc minute is divided into 60 arc seconds. Table 3-2
shows how arc seconds relate to elevation at a distance.

Table 3-2. Arc Seconds vs. Feet/Meters

At 100’ /30m

At 500’ / 152m

At 1000’ / 305m

1 arc second =

.0005’ / .00015m

.0024’ / .00073m

.0048’ / .00146m

5 arc seconds =

.0024’ / .00073m

.012’ / .00366m

.024’ / .00732m

10 arc seconds =

.0048’ / .00146m

.024’ / .00732m

.048’ / .01463m

15 arc seconds =

.0072’ / .00219m

.036’ / .01097m

.072’ / .02195m
