SECTION 1 • INTRODUCTION

 

 

Thank  you tor  selecting  our  accelerometer  for your  application.  You have 
made an outstanding choice by selecting this OMEGA Engineering product 
and we are  glad to provide you  with  the best accelerometer  that  modern 
technology  can  offer.  This  equipment  has  set  the  world  standard  for 
excellence  and should provide you with years of faithful service.

 

 

Before  you use your accelerometer, please read this manual  to ensure the 

maximum  performance of your unit.  If you  should have  any problem  with 
this equipment, please call our Customer Service Department at

you between 8:30 AM and 5:00

 

PM (EST) Monday through Friday.

 

 

 

SECTION  2 • UNPACKING  YOUR ACCELEROMETER

 

 

Remove the packing list and verify that all equipment has been received.  If 

there are  any  questions about the shipment,  please call OMEGA Customer 
Service Department  at

 1-(800) 622-2378  or (203) 359·1660.

 

 

Upon receipt  of the shipment, inspect  the container  and equipment  for any 
signs of damage.  Take  particular note  of any evidence  of rough handling in 
transit. Immediately report any damage to the shipping agent.

 

 

NOTE:

 

The carrier will not honor any claims unless  all shipping material is saved for 

their  examination.  After examining and removing contents,  save the packing 
material and carton in the event reshipment Is necessary.

 

The  accelerometer comes  packaged in  its own  protective  case  which  may

 

also contain a cable (Integral or separate).  Each accelerometer is equipped 
with an insulating  thermal  boot.  The  boot  may  already  be  fitted  over  the 
accelerometer  and  may

 

or  may  not  be  removable  depending  upon  the 

model.  The package may also contain an isolating mounting stud, spacing 
washers,  a magnet  assembly, or other special  part.   Care  should be taken 
not  to lose  any part  including  the  case  which  can continue  to be used  to 
accommodate  the accelerometer, accessories, and calibration data sheet.

 

 

Notice  that the serial number and sensitivity of the unit is indicated on the 

calibration  data sheet.  The  data sheet  also  includes  performance 
specifications that are endorsed for the particular unit.
