Vibration testing is performed to determine the resistance of equipment to vibration expected in its shipment and application environments. Vibration can cause:
- Wire chafing
- Loosening of fasteners
- Intermittent electrical contacts
- Touching and shorting of electrical parts
- Seal deformation
- Component fatigue
- Display / Touch Panel misalignment
- Cracking and rupturing
- Excessive electrical noise
Trimble Kenai®, Yuma® 2, Nomad® 1050, Juno® T41 and Ranger™ 3 all passed the following tests:
- Procedure I, General Minimum Integrity: Power Spectral Density = 0.04G²/Hz, 20 to 1000Hz, descending 6dB/oct to 2000Hz. Three axes are tested, one-hour per axis.
- Procedure II, Vibration and Loose Cargo: a Logarithmic sweep 5 to 500Hz beginning at 0.20" displacement. Three axes are tested, 30 minutes per axis.
