AC/DC Current Clamp for Oscilloscopes

The Pintech PT-2740 is a current clamp probe that measures AC and DC currents from 2 A to 500 A peak-to-peak. It connects to any oscilloscope using a standard BNC connector on a 2 m coaxial cable. The probe operates up to 300 kHz bandwidth with a stated accuracy of ±2% plus 5 mV.

Suited for power and automotive diagnostics

Engineers and technicians measuring power waveforms, motor drives or vehicle electrical systems will find the dual ranges of 20 mV/A and 2 mV/A useful. Buyers who need to clamp conductors larger than 11 mm diameter or who require a probe powered directly by the oscilloscope should look at other models.

300 kHz bandwidth defines measurement speed

The –3 dB bandwidth of DC to 300 kHz determines the fastest current transients the probe can capture. Rise time is specified at 1.2 µs, so signals with faster edges will be attenuated. Verify that this bandwidth covers the harmonics you need to analyse.

Questions about this item

Will the 9 V battery need frequent replacement during daily use?

The probe draws little current; the green LED stays lit above 6.5 V, so a standard alkaline cell typically lasts many sessions before the low-battery indicator triggers.

What measurement limit appears first when logging continuous current on the 20 mV/A range?

The 20 mV/A range tops out at 60 A peak, so sustained currents above that level will hit the overload LED before the probe reaches its 500 A peak capability on the 2 mV/A range.

How much heat or noise does the clamp generate during an all-day test session?

The probe body remains cool because it only senses the magnetic field; specified output noise is 2 mV and there is no fan or active cooling to add audible noise.
