Safety & Warnings
The manual includes several safety warnings and precautions:
1. Ground the Instrument: The instrument’s chassis and cabinet must be connected to an electrical ground to minimize shock hazards. The power cable should be plugged into an approved three-conductor electrical outlet, and the ground connection should not be altered.
2. Do Not Operate in an Explosive Atmosphere: The instrument should not be used in the presence of flammable gases or fumes, as this poses a safety hazard.
3. Keep Away from Live Circuits: Operating personnel should not remove instrument covers. Component replacement and internal adjustments should be done by qualified maintenance personnel. The power cord should be disconnected before removing covers, and dangerous voltages may still exist even with the power cable removed.
4. Do Not Service or Adjust Alone: Internal service or adjustments should not be attempted unless another person capable of rendering first aid and resuscitation is present.
5. Do Not Substitute Parts or Modify the Instrument: Unauthorized modifications or installation of substitute parts should be avoided. The instrument should be returned to B&K Precision for service and repair to maintain safety features.
Warnings and Cautions:
– A warning statement highlights a procedure, practice, or condition that could result in injury or death if not followed correctly.
– A caution statement highlights a procedure, practice, or condition that could result in damage to the product if not followed correctly.
Specific warnings include:
– Do not alter the ground connection to avoid electric shock.
– Disconnect the power cord before removing covers to avoid electrical shock hazards.
Specific cautions include:
– Check the rear panel AC line voltage indicator before connecting the line cord to the AC mains to avoid destroying AC line fuses.
– Follow proper procedures for handling, storing, and transporting parts containing electro-static discharge (ESD)-sensitive components to avoid damage.
