Vibration withstand for standard version:
Tests with sine vibrations carried out at ambient with scanning each of the three main axes of the holder.
st
Spectrum: 1 segment (2 to 16 Hz) constant displacement x = 5 mm peak.
nd
2 segment (16 to 250 Hz) constant acceleration = 5 g peak.
Exponential scanning speed: 1 octave per minute.
Duration: 2 hours per axis.
