Special Precautions
The following precautions should be observed when performing the accelerometer mounting and removal
procedures given below.
WARNING:
Do not break cement bond by striking accelerometer or by using any tool that makes a
metal-to-metal contact with the accelerometer. Always break the bond with the supplied
tool after the cement has been softened, by twisting or torquing the accelerometer,
stressing the bond in shear.
CAUTION:
Exercise care to prevent getting adhesive or solvent on the accelerometer connector.
Mounting Procedure
1. Ensure that mating surfaces are smooth and flat.
2. Remove all traces of grease, oil and oily residue from mating surfaces using cotton swabs and solvent.
3. Apply a tiny drop of Cyanoacrylate, approximately 1/5 the diameter of the mounting pad (side opposite
gold lid).
