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. 
If this device is damaged or something is missing, contact the place of purchase immediately. 
This manual contains information and warnings that must be followed to ensure safe operation as well as 
maintain the meter in a safe condition. 
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 must 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.
