Current probe

ETA5301A/B AC / DC current probe

ETA5301A/B is a universal oscilloscope current probe, which is compatible with more than 95% of the oscilloscopes on the market. The frequency response of up to 300KH ranges from 50mA to 200A (peak value), and the output terminal of BNC. Connecting oscilloscope can accurately measure AC or DC current waveform. Three-position sliding switch on handle panel can choose range and ON/OFF.

 

- AC/DC dual purpose

- Current measurement range: 50mA to 200A

- Measurable thin cables (11mm)

- Narrow clamp design is convenient for use in narrow space with dense wiring.

- 9V subtractive battery, 13 hours continuous operation

- Accurate measurement, analysis and display of distortion current waveforms and harmonic wave


Elecical characiersics are applicable to any brand of osciloscope that has been verifed. The oscioscope must be preheated for atleast 20 minutes and used inthe temperalure range of 10-30'℃ and 0-80% RH.
