Calibration of Verification Rods and Long Parallel Plane Blocks
Taratura di blocchetti piano paralleli lunghi e aste di riscontro

Calibration that determines the deviation from the nominal length at the centre of the surfaces 20 °C, performed with a horizontal measurer on which the laser interferometer is assembled.
Calibration instrument:

• Parallel plane blocks

Measuring range:

• between 100 and 1000 mm

Measurement uncertainty:

• (0.6 + 0.3 L) µm

The numeric value of the nominal length expressed in meters is indicated by L.
* Measurement uncertainty corresponds to a confidence interval of approx. 95%.
Strumento in taratura:

• Blocchetti piano paralleli

 
Campo di misura:

• da 100 a 1000 mm

 
Incertezza di misura:

• (0,6 + 0,3 L) µm

Si indica con L il valore numerico della lunghezza nominale espressa in metri.
