Safety & Warnings
The safety warnings and precautions explicitly present in the manual are as follows:
1. Ground the Instrument: The instrument chassis and cabinet must be connected to an electrical ground to minimize shock hazard. The instrument is grounded through the ground conductor of the supplied three-conductor AC power cable, which must be plugged into an approved three-conductor electrical outlet. Altering the ground connection can result in an electric shock.
2. Do Not Operate in an Explosive Atmosphere: The instrument should not be operated in the presence of flammable gases or fumes, as this constitutes a safety hazard.
3. Keep Away from Live Circuits: Instrument covers must not be removed by operating personnel. Component replacement and internal adjustments should be made by qualified maintenance personnel. The power cord should be disconnected before removing instrument covers and replacing components. Dangerous voltages may exist even with the power cable removed, so power and circuits should be disconnected and discharged before touching them.
4. Do Not Service or Adjust Alone: Internal service or adjustment 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: Substitute parts should not be installed, and unauthorized modifications should not be performed. The instrument should be returned to B&K Precision for service and repair to ensure safety features are maintained.
Warnings and Cautions:
– Warning: Do not alter the ground connection as it can result in an electric shock. The power jack and mating plug meet IEC safety standards.
– Warning: To avoid electrical shock hazard, disconnect the power cord before removing covers. Servicing should be referred to qualified personnel.
– Caution: Before connecting the line cord to the AC mains, check the rear panel AC line voltage indicator. Applying a different line voltage can destroy the AC line fuses. Fuses should be replaced only with those of the specified voltage and current ratings.
– Caution: The product uses components that can be damaged by electro-static discharge (ESD). Proper procedures for handling, storing, and transporting parts and subassemblies containing ESD-sensitive components should be followed.

Basic Usage and Operation Tips
Before using the Bk-precision-5491b, ensure the test leads are properly connected and in good condition. Select the appropriate measurement mode and range for your application. For unknown values, start with the highest range to prevent damage. Always connect the black lead to the common (COM) terminal and the red lead to the appropriate input terminal based on the measurement type. Use the hold function to freeze the displayed value when needed, and enable the backlight for better visibility in dim environments.
Troubleshooting and Maintenance
If the multimeter displays erratic readings or fails to power on, check the battery and replace it if necessary. Inspect the test leads for damage or loose connections. Clean the device regularly with a soft, dry cloth and avoid exposure to moisture or extreme temperatures. If the device is not functioning correctly after basic troubleshooting, consult the manual for detailed diagnostic procedures or contact customer support.
Safety Reminder
Always observe proper safety precautions when using the Bk-precision-5491b. Do not exceed the maximum input ratings to avoid electric shock or damage. Use caution when measuring high voltages and currents, and never operate the device with wet hands or in damp environments. Properly disconnect test leads before changing measurement modes to prevent accidental short circuits or injury.
