Precision current measurement up to 1400A

The Pintech PT740-3A is an AC/DC current probe designed for oscilloscope users who need to capture waveforms up to 150kHz bandwidth. It handles peak currents from 0.2A to 1400A across two selectable ranges and supports DC measurements from 0.4A. The probe connects via a 2m BNC cable and operates at a maximum working voltage of 600V rms. It suits engineers and technicians performing power analysis or fault diagnosis on electrical systems.

Dual-range output scaling and adapter power

The probe provides two output ratios: 10mV/A for the lower range and 1mV/A for the higher range, letting the oscilloscope display current directly without external math. A supplied mains adapter powers the unit by default, removing the need to manage battery life during long test sessions. Green and red LEDs indicate battery capacity above 6.5V and overload conditions respectively. Automatic shutdown after 10 minutes conserves power if the probe is left on accidentally.

Jaw opening fits 30mm cables or dual busbars

Installation requires clamping the probe around a single conductor up to 30mm diameter or two cables up to 24mm each, with busbars up to 2×31.5×10mm also supported. The 224×97×44mm body weighs 440g and must be positioned carefully because conductor position inside the jaw can influence readings by 0.5%. DC zero adjustment is available to null offsets before measurement. Users needing battery-powered operation must request that variant separately, as batteries are not included with the standard adapter version.

Questions about this item

Does the PT740-3A probe require battery replacement, and how will I know when it is low?

The probe runs on an internal battery. A green LED lights while voltage stays above 6.5 V, and the unit powers off automatically after 10 minutes of inactivity.

What is the first measurement limit reached when clamping continuously near the top of the 1400 A range?

The working-voltage ceiling of 600 V rms and the common-mode limit of 600 V rms are reached before the current range itself.

How much heat or noise does the PT740-3A produce during all-day use?

Insert impedance stays low at 0.39 mΩ at 50 Hz and 58 mΩ at 1 kHz, so self-heating is minimal, and the probe has no fan or moving parts for silent operation.
