Non-intrusive testing

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.

• Long reach, 8 mm, angled jaw
• Wide range coverage from 10 mA up to 60 A
• Switchable range 20 / 60 A
• Exceptional value and accuracy
• Incorporated into numerous automotive kits
• Available with BNC or 4 mm Banana connector
• One push zero function
• Low battery warning

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.

• Medium reach, 20 mm, extended jaw
• Measures 5 mA to 30 A DC
• Exceptional accuracy
• Parasitic measurements without battery disconnection
• High resolution of current values as low as 5 mA
• Thumbwheel style zero setting
• Low battery warning

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).

• Short reach, 25 mm wide jaw
• Measures 5 mA to 30 A DC
• Improved sensitivity
• External noise rejection
• Increased accuracy
• Fast response time
• Parasitic measurements without battery disconnection
• High resolution of current values lower than 5 mA
• One push zero function
• Auto power-down facility
• Low battery warning   

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.

• Short reach, 35 mm wide jaw
• Measures 1 A to 2000 A DC
• External noise rejection
• Increased accuracy
• Fast response time
• Switchable range: 200 / 2000 A
• One push zero function
• Auto power-down facility

Combine your current clamps with fuse extensions (PP967) to gain access to even more circuits on the vehicle.
