Safety & Warnings
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:
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
Warnings and Cautions:
– A WARNING statement calls attention to an operating procedure, practice, or condition, which, if not followed correctly, could result in injury or death to personnel.
– A CAUTION statement calls attention to an operating procedure, practice, or condition, which, if not followed correctly, could result in damage to or destruction of part or all of the product.
Specific Warnings and Cautions:
– WARNING: Do not alter the ground connection. Without the protective ground connection, all accessible conductive parts (including control knobs) can render an electric shock.
– WARNING: To avoid electrical shock hazard, disconnect power cord before removing covers. Refer servicing to qualified personnel.
– CAUTION: Before connecting the line cord to the AC mains, check the rear panel AC line voltage indicator. Applying a line voltage other than the indicated voltage can destroy the AC line fuses. For continued fire protection, replace fuses only with those of the specified voltage and current ratings.
– CAUTION: This product uses components which can be damaged by electro-static discharge (ESD). To avoid damage, be sure to follow proper procedures for handling, storing, and transporting parts and subassemblies which contain ESD-sensitive components.

Basic Usage and Operation Tips
Before using the Bk-precision-4078, ensure the device is properly calibrated and the batteries are fully charged. Select the appropriate measurement mode using the rotary dial. Always connect the test leads correctly: black to the common terminal and red to the corresponding input terminal based on the measurement type. For voltage and resistance measurements, start with the highest range and adjust downward for accuracy. Use the data hold feature to freeze readings for easier documentation. When measuring current, never exceed the maximum rated input to avoid damage.
Troubleshooting and Maintenance
If the multimeter displays erratic readings or fails to power on, check the battery condition and replace if necessary. Inspect test leads for damage or wear and replace if faulty. Clean the device regularly with a soft, dry cloth and avoid exposure to moisture or extreme temperatures. If the device shows “OL” or overload indicators, reduce the measurement range or check the circuit connections. For persistent issues, consult the detailed manual or contact authorized service centers.
Safety Reminder
Always observe standard electrical safety precautions when using the Bk-precision-4078. Avoid measuring voltages or currents beyond the specified limits to prevent electric shock or damage. Use insulated gloves and tools when working with high voltages. Disconnect power before connecting or disconnecting test leads. Never attempt to open or repair the device yourself; seek professional assistance to maintain safety and device integrity.
