Page 8: Adhesive Mount
A precision-machined mounting surface with a minimum finish of 32 in (0.0008 mm) is recommended. (If, and STEP 1: Prepare a smooth, flat mounting surface. A minimum surface finish of 32 in (0.0008 mm) generally only if, it is not possible to properly prepare the test structure mounting surface, consider adhesive mounting as works best. - Page 9 One cable type cannot satisfy all applications. Industrial 4.2-1 ADHESIVE MOUNT REMOVAL applications often require shielded, twisted-pair cables to (other than wax) reduce the effects of EMI and RFI that is present near Caution: It is usually difficult or near impossible to electrical motors and machinery.

STEP 4: Finally, connect the remaining cable end to the signal conditioner. 6.0 Signal Conditioning For optimum performance and flexibility, high sensitivity DC accelerometers benefit from a good stable, low noise dc power supply for excitation (Fig. 6). It should be regulated and stable to within 0.1% or better. -
Page 11: Recalibration Service
For these reasons, it is recommended that a recalibration cycle be established for each accelerometer. This schedule is unique and is based on a variety of factors, such as: extent of use, environmental conditions, accuracy requirements, trend information obtained from previous calibration records, contractual regulations, frequency of “cross- Figure 9. -

Since the Back-to-Back Calibration technique relies on For stud-mount sensors, always mount the accelerometer each sensor experiencing an identical acceleration level, directly to the reference standard. Ensure that the mounting proper mounting of the test sensor to the reference surfaces are smooth, flat, and free of any burrs. Always use a standard is imperative. - Page 13 PCB®, ICP®, Swiveler®, Modally Tuned®, and IMI® with associated logo are registered trademarks of PCB Piezotronics, Inc. in the United States.
