Safety & Warnings
The safety warnings and precautions explicitly present in the manual include:
1. Ground the instrument to minimize shock hazard. The instrument chassis and cabinet must be connected to an electrical ground using the supplied three-conductor AC power cable. Do not alter the ground connection as it can lead to electric shock.
2. Do not operate the instrument in an explosive atmosphere, such as in the presence of flammable gases or fumes, as it constitutes a safety hazard.
3. Keep away from live circuits. Instrument covers should not be removed by operating personnel. Component replacement and internal adjustments should be made by qualified maintenance personnel. Always disconnect the power cord before removing covers and replacing components.
4. Do not service or adjust the instrument alone. Ensure another person capable of rendering first aid is present.
5. Do not substitute parts or modify the instrument. Unauthorized modifications can compromise safety features. Return the instrument to B&K Precision for service and repair.
6. Warning statements indicate procedures or conditions that could result in injury or death if not followed correctly. Caution statements indicate procedures or conditions that could result in damage to the instrument.
7. Specific warnings include not altering the ground connection and disconnecting the power cord before removing covers to avoid electrical shock hazards.
8. Caution is advised before connecting the line cord to the AC mains to check the rear panel AC line voltage indicator. Applying incorrect line voltage can destroy AC line fuses. Replace fuses only with those of specified voltage and current ratings.
9. The product uses components sensitive to electro-static discharge (ESD). Proper procedures for handling, storing, and transporting ESD-sensitive components should be followed to avoid damage.
