Recalibration 

Sensitivity and Zero Measurand Output calibration should be performed at 6 to 12 month intervals, depending on usage.  
Ordinarily, recalibration need be performed only at 12 month intervals if it is known that the angular rate sensor has not been 
used  beyond  its  rated  specifications.    If  the  unit  is  used  under  severe  environments,  it  may  be  desirable  to  use  shorter 
calibration intervals. 

Contact Endevco for local  calibration facility information or return the 7310A unit to Endevco  for recalibration.  Endevco 
maintains an angular rate recalibration service with A2LA traceability in the United States.  

Dirty units may be wiped clean using a damp cloth and a solvent such as acetone.
