1-5 

Figure 1-1 shows the relation between frequency of floor vibration and vibration transmittance of 
the instrument.    Since the vibration transmittance is maximum at the resonance point (about   
2 Hz) of the anti-vibration mount provided with the instrument, the allowable amplitude is 
minimum at this point.   
 
NOTICE:  Please consult with us if the floor vibration exceeds the allowable values. (Vibration 

should be measured in advance if it is expected to cause a disturbance.)
