AC/DC Current Probe for Oscilloscopes

The Pintech PT740-2A is a clamp-style current probe designed for oscilloscope users who need to measure both AC and DC currents up to 600A. It connects via a standard BNC connector, making it compatible with most oscilloscopes for power analysis and electrical troubleshooting tasks.

Bandwidth and Measurement Limits

The probe operates from DC to 150kHz bandwidth with two selectable ranges covering peak currents from 0.2A to 60A and 60A to 600A, and DC ranges from 0.4A to 60A and 60A to 600A. Accuracy is rated at ±1.5% plus 5mV, while the maximum working and common-mode voltage is 600V rms. Jaw opening accepts a single 30mm cable or dual 24mm cables.

Installation and Common Issues

Connection is straightforward: attach the BNC cable to the oscilloscope input, select the appropriate 10mV/A or 1mV/A ratio, and clamp around the conductor. The probe requires an external adapter for power; a battery-powered option exists but batteries are not included. Users must perform DC zero adjustment before measurements and ensure the jaw is fully closed to avoid position errors of 0.5%.

Questions about this item

Which current range should I choose for my measurements?

The probe offers two selectable ranges: a low range covering 0.2 A to 60 A peak or 0.4 A to 60 A DC, and a high range covering 60 A to 600 A for both peak and DC. Choose the low range for small signals and the high range for larger currents up to 600 A.

What does the 150 kHz bandwidth mean when I connect this to my oscilloscope?

The 150 kHz bandwidth means the probe accurately passes signal components from DC up to 150 kHz, with a rise/fall time of 2.3 µs. Signals with frequency content above 150 kHz will be attenuated, so ensure your measurement band fits within this limit.

How does the BNC output and 10 mV/A or 1 mV/A scaling affect what I see on the scope?

The BNC cable delivers a voltage proportional to current: 10 mV per ampere on the low range (100:1) and 1 mV per ampere on the high range (1000:1). The scope must present a 1 MΩ
