The Unseen Risks of Probing Power Supplies The recent article "Testing UPS Output Waveforms" on a dev publication caught attention for its exploration into the testing of uninterruptible power supplies (UPS) using oscilloscopes.
The author's cautionary approach to probing high voltage equipment is well advised, and their investigation highlights pressing concerns about the safety and reliability of modern electronics.
The difficulty in safely connecting measurement equipment to UPSs stems from the potential for creating unintended circuit paths that could damage sensitive instruments or cause electrical shock.
