The Yokogawa 701929 is a clamp-type current probe engineered for non-invasive AC and DC current measurement in power electronics, automotive, and industrial applications. It connects directly to compatible Yokogawa DL series instruments via the 1 MΩ BNC input, drawing power from the instrument’s probe interface and eliminating the need for external amplifiers or power supplies. The probe automatically integrates with DLM series oscilloscopes, allowing direct current readout and probe-based parameter selection without manual conversion factor entry.
