Pico Technology's range of accessories saves valuable workshop time by offering electrical diagnosis which is fast and non-intrusive. As we know, diagnosis is best carried out prior to any dismantling, with minimal intrusion into the vehicle. Pico's coil-on-plug (COP) probe, along with the range of both fuse extensions and current clamps, make this objective easier than it’s ever been.
Pico’s range of current clamps is a group of accessories that suits multiple applications. They can be used to confirm that a component under test is connected to a complete circuit and, more importantly, that an event took place. The event may be the operation of any component that consumes current, such as solenoids, injectors, motors, actuators, pumps, volume or pressure control valves, and relays. All this information can be obtained by simply placing a component cable in the jaws of a current clamp.
As current flows through the cable, it creates a magnetic field. The clamp senses this field and converts it to voltage. This voltage is then relayed to PicoScope via a single connection, where it is converted and displayed to the technician as current.
TA018 20/60 A:
A perfect all-rounder current clamp with the ideal jaw for reaching into harnesses where access is limited.
TA234 30 A:
A clamp with a medium reach, 20 mm jaw for measuring low currents with improved accuracy.
Parasitic drain is a typical application where the large, 20 mm jaw is sufficient to accept battery cables without the need for disconnection.
TA189 30 A:
A clamp with a wider, 25 mm jaw for additional flexibility when connecting to larger cables. The sensitivity, resolution and response time have all improved, along with a convenient auto power-down feature when not in use (auto power-down can be prohibited if required).
TA167 200 A / 2000 A:
Allows for easy clamping of large conductors for high current measurements such as starter motor and charging currents. The peak current of 2000 A accommodates the typical inrush currents associated with high compression engines during cranking.
