Fluke i3000S Current Probe, 3 kA AC Max, Voltage Output

Fluke Current Probe, 3kA Maximum AC Current, 178mm Maximum Conductor Size - 2584888

This current probe is a flexible Rogowski-type clamp used to measure alternating current in confined or hard-to-reach installations when connected to oscilloscopes, recorders or data loggers. It is suitable for industrial and field use where high-current measurements are required and when portability and a lightweight measuring head are advantageous.

Features & Benefits

• Measures up to 3000 A ac rms for large system diagnostics
  Switchable 30 A / 300 A / 3000 A ranges for versatile scaling
  ±1% accuracy at 25 °C for precise readings in the mains band
  Output voltage sensitivity selectable for direct instrument input
  2m cable with BNC termination for convenient equipment connection
  Powered by 2 x AA batteries delivering about 400 h for extended use

**Applications**

• Suitable for power-quality analysis with portable oscilloscopes
  Ideal for commissioning large motors and drives up to 3 kA
  Used with recorders and data loggers in load monitoring
  Can be used for troubleshooting in cramped electrical panels
  Used for measurements where insulated conductors exceed standard clamps

What environmental limits affect head operation?

The measuring head can operate between −20 °C and +90 °C, allowing use near elevated-temperature conductors.

How does external magnetic influence affect measurements?

External currents more than 200mm from the head contribute about 1% of range, reducing interference when positioned appropriately.

What frequency band does it cover for accurate readings?

It provides useful response from 10 Hz up to 50 kHz with phase error under ±1° in the 45–65 Hz band.

What connection accessories are supplied for different instruments?

The unit includes a safety BNC lead and a BNC-to-banana safety plug adapter for compatibility with various test devices.

Supplied with

2 x AA alkaline batteries, BNC to 4mm plug adaptor and operator's manual.
