Current Clamps

The PicoBNC+ 2000A AC/DC current clamp (TA388) is designed for automotive technicians who need to measure high currents up to 2000 amps without cutting, disconnecting, or stripping wires. Simply clamp the jaws around the cable and plug into your PicoScope — the clamp auto-configures and ranges automatically, making starter motor current draw testing and alternator output diagnostics fast and non-intrusive.

The PicoBNC+ equipped TA496 60 A AC/DC compact current clamp from Pico Technology is designed for automotive technicians using PicoScope 4225A and 4425A oscilloscopes who need to measure low currents in tight engine spaces. Its reduced form factor improves accessibility around fuel injectors, sensors, and actuators, while the scope-powered PicoBNC+ technology eliminates the need for batteries or external power supplies.Automatic probe recognition saves you from having to select the probe in the software. Automatic range switching means you don’t have to change the range on the probe itself, just select a range in the software and the probe will take care of itself. You don’t even have to zero the clamp, PicoBNC+® can take care of that too.

The TA473 PicoBNC+ 60A AC/DC current clamp from Pico Technology is engineered for fuel injector and fuel pump diagnostics on modern vehicles. Measuring currents from 10mA to 60A, this automotive current probe delivers superior performance compared to legacy TA018 and TA234 models, enabling technicians to capture precise injector waveforms and diagnose fuel system faults with confidence.The clamp can be auto-configured by PicoScope software when it is connected to the scope. Ranging is carried out automatically with no user switching required. The clamp is powered via the scope and therefore does not require any batteries. Additionally, the clamp is auto-zeroed whenever it is connected to the scope.

The TA408 PicoBNC+ 100A AC/DC current clamp from Pico Technology is designed for battery drain and parasitic draw diagnostics on modern vehicles. This closed-loop current probe delivers exceptional 5mA resolution for low-current measurement, making it ideal for identifying parasitic drain issues that conventional clamps miss.

The TA189 30A precision current clamp from Pico Technology features a large 25mm jaw designed for sensor, actuator, and long-term battery drain testing on passenger and commercial vehicles. This closed-loop current clamp measures from 5mA to 30A with improved sensitivity and lower noise than conventional clamps, making it ideal for diagnosing low-current faults in modern vehicle electrical systems.

The 200 A / 2000 A current clamp allows you to measure up to 2000 amps without cutting, or disconnecting or stripping wires. Simply clamp the jaws around the cable to be tested and plug the clamp into your PicoScope.

The TA018 20A/60A DC Current Clamp from Pico Technology measures low-current signals from fuel injectors, sensors, and actuators between 10mA and 60A. Designed for technicians diagnosing engine management systems, this dual-range current clamp displays current waveforms on PicoScope oscilloscopes without breaking into circuits, making it ideal for testing fuel injector performance, fuel pump draw, and sensor/actuator operation.

The TA019 600 A DC current clamp from Pico Technology measures starter motor current draw, charging currents, and enables quick compression testing for petrol engines. Designed for automotive technicians, this clamp works with PicoScope oscilloscopes to capture AC or DC currents up to 600 amps without breaking into circuits or disturbing insulation.
