Automotive current clamp for oscilloscopes

The Pintech PT-721 is a new AC current clamp probe built for automotive and electrical technicians who need to capture waveforms on an oscilloscope or multimeter without breaking the circuit. It accepts conductors up to 53 mm diameter and delivers three selectable ranges covering 0.1 A to 1200 A. A BNC connector and insulated coaxial cable provide direct compatibility with standard test instruments. CE certification confirms compliance with declared safety standards.

Upgrade from fixed-range or lower-bandwidth probes

This probe replaces single-range clamps that force you to swap heads or tolerate coarse resolution at low currents. The 10 Hz to 100 kHz bandwidth captures fast transients that basic 1 kHz tools miss, while the three conversion ratios (100 mV/A, 10 mV/A, 1 mV/A) keep signal amplitude usable across the full span. The jump is worth it when you regularly measure both parasitic drains below 1 A and starter or inverter currents above 200 A on the same job.

Clamp-on installation with BNC termination

Installation is limited to opening the jaw, clamping around a single conductor, and selecting the range that matches the expected current. The 3.5 s rise time means the probe settles quickly after range changes. Common errors include clamping multiple conductors (which cancels the reading), exceeding the 600 V rms CAT III working voltage, or leaving the probe on the 1200 A range for extended periods beyond the 20-minute thermal limit. The 500 g weight and 216 mm length are manageable for one-handed use in tight engine bays.

Questions about this item

What is the maximum jaw opening of the PT-721 clamp probe?

The clamp jaw opens to a maximum diameter of 53mm or 2.17in, allowing it to fit around conductors up to that size.

How do you connect the PT-721 to an oscilloscope, and what is the required input impedance?

Connect the insulated BNC coaxial cable to the oscilloscope BNC input; the probe requires a load impedance of 1M and 47pF for correct operation.

What limits the continuous current rating at higher frequencies on the PT-721?

The probe handles 1000A continuous above 1kHz, but proportionality limits apply outside that frequency, and 1200A is only allowed for about 20 minutes.
