This document is an instruction manual for Endevco® high shock accelerometers, including models, installation methods and precautions, etc.
This manual provides detailed instructions for installing, handling, and maintaining Endevco® high shock accelerometers. It covers mounting surface preparation, cable handling, and demounting procedures. Special precautions are given for handling undamped models to avoid resonance damage. The document also includes recommendations for adhesive use, thread locking, and cable strain relief to ensure accurate shock measurements.
The manual emphasizes ESD-safe handling and includes a resistance test for initial checkout. Mounting surfaces must be smooth and clean, with recommended acoustic couplants or adhesives for optimal transmissibility. Demounting procedures are provided for both hardware-mounted and adhesive-mounted sensors, with warnings against damaging impacts or solvent immersion.
