This section provides general maintenance procedures that increase the effectiveness and useful
life of your 130-SMHR/9 Strong Motion Accelerograph.
In theory, no maintenance is needed - in practice it is to the user's advantage to inspect a unit at
least every year or before and after any long-term field deployment. Shock, vibration and effects
the user has no control over (vandalism for example) may occur and cause leaks in the case that
result in dust or moisture accumulating inside and damaging components. For these reasons it is
best to perform an annual inspection, clean off the boards, ensure that all components are in
good condition and that installed chips are properly seated and that all boards and connectors
are firmly mated. If you encounter a recurrent problem, please contact REF TEK.
Replacing the Compact Flash™
If the Compact Flash™ needs to be replaced:
1. With power on, flip the draw latches (Item 3).
2. Remove the enclosure lid (Item 1) and set it gently on the side next to the base plate (as shown below
not upside-down) to remove the compact flash and avoid contamination of the seal.
Note: Be careful not to break the cables attached to the accelerometer and Compact/Flash board. If possible leave
the ground cable attached to the case.
