Safety & Warnings
Normal use of test equipment exposes users to electrical shock hazards, especially when testing where exposed voltage is present. A current of 10 milliamps passing through the heart can be lethal, and voltages as low as 35 volts can be dangerous. To minimize risks, follow these precautions:
– Avoid unnecessary exposure to high voltage. Remove housings and covers only when necessary, turn off equipment while making test connections, and discharge high voltage capacitors after removing power.
– Familiarize yourself with the equipment 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.
– Use the “one hand in the pocket” technique when handling an instrument probe to avoid creating a ground return path.
– Remember that ac line voltage is usually present on some power input circuits even if the equipment is turned off.
– Treat all two-wire ac equipment as “hot chassis” unless confirmed otherwise, and always use an isolation transformer when servicing.
– Use only a 3-wire outlet for equipment with a 3-wire ac power plug to maintain safety.
– 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 recommended.

Basic Usage and Operation Tips
Before powering on the device, ensure all connections are secure and set the output controls to zero. Use the front panel or GPIB commands to configure the desired voltage and current limits. When operating in constant voltage mode, the supply maintains a steady voltage while adjusting current as needed. Conversely, in constant current mode, the device regulates current output to protect sensitive components. Always monitor the digital display during operation to verify output parameters.
Troubleshooting and Maintenance
If the power supply fails to output the expected voltage or current, check all cable connections and verify the GPIB communication settings. Ensure that the overcurrent or overvoltage protection has not been triggered; if so, reset the device after correcting the fault condition. Regularly clean the exterior and ventilation grills to prevent overheating. Avoid exposing the unit to excessive dust or moisture to maintain optimal performance.
Safety Reminder
Always follow proper safety procedures when operating the Bk-Precision VSP6020GPIB. Do not exceed the specified voltage and current ratings to avoid damage or personal injury. Use insulated tools and wear appropriate protective equipment when making electrical connections. Disconnect the power supply from the mains before performing any maintenance or servicing tasks.
