Safety & Warnings
The following safety precautions must be observed during all phases of operation, service, and repair of the instrument:
1. Ground the instrument to minimize shock hazard. The chassis and cabinet must be connected to an electrical ground through the supplied three-conductor AC power cable, which must be plugged into an approved three-conductor electrical outlet. Do not alter the ground connection to avoid electric shock.
2. Do not operate the instrument in an explosive atmosphere, such as in the presence of flammable gases or fumes, as this constitutes a safety hazard.
3. Keep away from live circuits. Operating personnel should not remove instrument covers. Component replacement and internal adjustments should be made by qualified maintenance personnel. Disconnect the power cord before removing covers and replacing components to avoid injury from dangerous voltages.
4. Do not service or adjust the instrument alone. Ensure another person capable of rendering first aid and resuscitation is present.
5. Do not substitute parts or modify the instrument. Unauthorized modifications or installing substitute parts can compromise safety features. Return the instrument to B&K Precision for service and repair.
Warnings and cautions are provided throughout the manual to highlight potential hazards. A WARNING indicates a risk of injury or death, while a CAUTION indicates a risk of damage to the product.
