Safety & Warnings
Normal use of test equipment exposes users to electrical shock dangers, as testing may involve exposed voltage. A current of 10 milliamps through the heart can stop most heartbeats, and voltages as low as 35 volts can be lethal. To reduce risk, follow these precautions:
– Avoid unnecessary exposure to high voltage. Only remove housings and covers when necessary, and turn off equipment when making test connections in high voltage circuits. Discharge high voltage capacitors after removing power.
– Familiarize yourself with the equipment being tested and its high voltage points, but be aware that high voltage may appear unexpectedly in defective equipment.
– Use insulated floor material or a large, insulated floor to stand on, and ensure work surfaces are not damp or wet.
– Employ the “one hand in the pocket” technique while handling an instrument probe to avoid contact with metal objects that could provide a ground return path.
– Remember that ac line voltage is usually present on some power input circuits whenever equipment is connected to an ac outlet, even if turned off.
– For equipment with a two-wire ac power cord, treat it as “hot chassis” unless confirmed otherwise, and use an isolation transformer between the ac outlet and the equipment under test.
– For equipment with a 3-wire ac power plug, use only a 3-wire outlet to keep exposed elements at earth ground.
– B&K Precision products are not authorized for use in applications involving direct contact with the human body or as critical components in life support devices.
– Never work alone; someone should be nearby to provide aid if necessary. Training in CPR and first aid is highly recommended.

Utilize the memory presets to quickly recall frequently used configurations. Monitor the digital display closely during operation to ensure parameters remain within safe ranges.
Troubleshooting and Maintenance
If the device fails to power on, check the main power connection and fuse status. In case of output instability or unexpected shutdowns, verify that the load does not exceed the maximum rated current and that ventilation is adequate to prevent overheating. Regularly clean the exterior and ventilation grilles with a dry cloth to maintain proper airflow. Avoid exposure to moisture or corrosive environments. For persistent issues, consult the detailed troubleshooting section of the manual or contact authorized service personnel.
Safety Reminder
Always follow proper safety protocols when working with electrical equipment. Disconnect the power supply before making any wiring changes. Use insulated tools and wear appropriate personal protective equipment. Avoid touching live terminals during operation to prevent electric shock. Ensure the device is grounded correctly to minimize the risk of electrical hazards. Adhering to these safety guidelines will help protect both the user and the equipment.
