1  Safety Summary 
The following safety precautions apply to both operating and maintenance personnel and 
must be observed during all phases of operation, service, and repair of this instrument. 
Before applying power, follow the installation instructions and become familiar with the 
operating instructions for this instrument. 
GROUND THE INSTRUMENT 
To minimize shock hazard, the instrument chassis and cabinet must be 
connected to an electrical ground. This instrument is grounded through the 
ground conductor of the supplied, three-conductor ac power cable. The power 
cable must be plugged into an approved three-conductor electrical outlet. Do not 
alter the ground connection. Without the protective ground connection, all 
accessible conductive parts (including control knobs) can render an electric 
shock. The power jack and mating plug of the power cable meet IEC safety 
standards. 
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE 
Do not operate the instrument in the presence of flammable gases or fumes. 
Operation of any electrical instrument in such an environment constitutes a 
definite safety hazard. 
KEEP AWAY FROM LIVE CIRCUITS 
Instrument covers must not be removed by operating personnel. Component 
replacement and internal adjustments must be made by qualified maintenance 
personnel. Disconnect the power cord before removing the instrument covers 
and replacing components. Under certain conditions, even with the power cable 
removed, dangerous voltages may exist. To avoid injuries, always disconnect 
power and discharge circuits before touching them. 
DO NOT SERVICE OR ADJUST ALONE 
Do not attempt any internal service or adjustment unless another person, 
capable of rendering first aid and resuscitation, is present. 
DO NOT SUBSTITUTE PARTS OR MODIFY THE INSTRUMENT 
Do not install substitute parts or perform any unauthorized modifications to this 
instrument. Return the instrument to B&K Precision for service and repair to 
ensure that safety features are maintained.
