Yokogawa current probes enable precise, non-intrusive measurement of AC, DC, and transient currents across a wide range of applications. Designed for seamless integration with our oscilloscopes and data acquisition systems, they deliver the precision, bandwidth, and safety needed for everything from low-level signals to high-power systems.

Relationship between the Current being Measured and Probe's Current Consumption
(Typical Values)
When using the DL/DLM/SL main unit to power the current probes, make sure that the total current consumption of the probes does not exceed the unit's probe power rating. For the probe power rating of each model, please check by the following information.
Supplementary information on current measurements
The Maximum input current value is derated with frequency;
as the frequency increases, the maximum input current rating decreases.
