Precision Current Probe for Oscilloscopes

The Pintech PT-3125A measures AC and DC currents up to 500 A peak-to-peak with a DC-to-12 MHz bandwidth. Its ±1 % accuracy and 30 ns rise time capture fast transients cleanly. A 20 mm jaw opening fits most conductors in automotive, industrial and lab environments. The BNC connector plugs directly into any oscilloscope input.

Build Quality and Daily Connectivity

Magneto-electric sensors deliver low-noise performance rated at 20 mA RMS. The clamp weighs 1.1 lb and includes a BNC cable plus adaptors for immediate use. Dual transformation ratios of 100 mV/A and 10 mV/A let you scale the signal for different current ranges without extra hardware. CE certification confirms compliance with basic safety requirements.

Upgrading from Basic Clamp Meters

This probe replaces handheld clamp meters that lack the bandwidth to view switching waveforms or inrush currents. The jump is worth it when you need to see current shape on an oscilloscope rather than just read an RMS value. It is not for users who only require simple multimeter-style readings or who need measurement beyond the 500 A peak limit.

Questions about this item

What bandwidth does the PT-3125A support and how does it limit measurable signals?

The probe covers DC to 12 MHz (-3 dB) with a 30 ns rise time, so current transients faster than about 30 ns will be attenuated and not faithfully captured.

What is the jaw opening of the PT-3125A and what conductor sizes will fit?

The clamp aperture is 20 mm (0.79 in), allowing measurement on cables or busbars up to that diameter.

How do I connect the PT-3125A to an oscilloscope and which scaling step is often missed?

Plug the supplied BNC cable into the probe's BNC output and the scope's BNC input, then set the scope channel to the probe's active transformation ratio — either 100 mV/A (10:1) or 10 mV/A (100:1) — matching the range selected on the probe.
