Automotive Accessories for Oscilloscopes

Test Leads

2-Pin Automotive Breakout Lead (TA012)

The TA012 breakout lead enables voltage readings to be taken from the numerous sensors in the engine compartment. The breakout lead is simply connected into the existing cable loom, and the output signal can then be taken from the two 4 mm banana plugs into the automotive oscilloscope using the TA000 test lead.

Note: A TA000 test lead will be required to convert the 4 mm banana plug connection on the TA012 into a BNC connector suitable for plugging into the PicoScope.

20:1 Attenuator (PP198)

The PP198 has been designed to allow fuel injector and primary ignition waveforms to be measured using PicoScope oscilloscope products.

The PP198 is a passive 20:1 attenuator. This means that a 20V signal at its input will appear as a 1V signal on the output. As the signal is attenuated, the PP198 allows voltages of up to 300 V to be measured.

Please note this attenuator should not be used for any high voltage measurements other than fuel injectors and primary ignition.

6-Way Universal Breakout Leads

Pico’s universal 6-way breakout leads eliminate the need to own many specific breakout leads for engine diagnostics. The breakout leads are available with 3 different sizes of connectors: 1.5 mm, 2.3 mm and 2.8 mm.

The breakout lead is simply connected into the existing cable loom and enables voltage readings to be taken from the numerous sensors in the engine compartment. The output signal can then be taken from the 4 mm banana plugs into the input of the PicoScope oscilloscope using the TA000 test lead.

Automotive Test Leads (TA000 and TA020)

The TA000 test lead has been custom made for automotive use with a Pico automotive oscilloscope. Its length (3 meters / approx 10 ft) allows the oscilloscope to be placed on the work bench away from the car being tested / repaired. A wide range of probes, clips and gators can be plugged into the 4 mm connectors at the end of the cable. The cable is fully screened to reduce noise pickup.

Also available is the TA020 automotive test lead. The TA020 is a 5 meter (approx 16 ft) version of the TA000.

BNC to BNC Lead with Earth Clamp (TA033)

Cable length: 3 m (9.8 ft)
Earth cable length: 1.5 m
Earth cable position: 1.5 m from each end

This 3 meter BNC to BNC cable includes an earth cable to protect your scope from high voltage leaks from the ignition system. BNC connectors feature insulating rubber boots and cable strain relief to protect the cable.

This cable is ideal for use with our Coil-on-Plug probe.

Coil-On-Plug Extension Lead (PP399)

Coil-on-Plug extension leads are the simple accessory that allow you to take accurate secondary ignition measurements on Coil-on-Plug ignition systems.

Coil-on-Plug extension leads are designed to aid diagnostics on secondary ignition circuits by allowing an HT measurement to be made when there are no, or limited access, to any spark plug leads.

Also available is a set of 4 COP extension leads that is ideal for use with cartridge coil-packs.

PP400 Coil-On-Plug Extension Lead (set of 4 leads)

Fuse Extension Leads (PP408)

Do you need to measure the current through a circuit but can’t find anywhere on the vehicle where you can connect your current clamp?
Fuse extension leads are a simple accessory that can save you valuable time.

Fuse extension leads are quick and easy to use: simply remove the fuse (of the circuit you wish to test) from your fusebox and replace it with a fuse extension lead. Now insert the fuse into the extension lead. To measure the current drawn, just connect your Pico current clamp to the extension lead.

A set of 2 fuse extension leads are supplied, allowing you to use the leads with both ATC and mini-ATC style fuses.

Inductive Pickup (TA032)

The TA032 Inductive Pickup is ideally suited for use with the ACE Misfire Detective.

Secondary Ignition Pickup (PP178)

Due to the high voltages involved in secondary ignition systems, it is not possible to make measurements by direct connection; attempting to make a direct connection will almost certainly damage the measuring instrument.

The PP178 is a capacitive pickup that simply connects around the insulation of an ignition circuit component such as a plug wire — this avoids the need for direct connection.

The PP178 comes with a shielded 2.5m (100 inch) lead. It is suitable for use with conventional ignition systems and most HEI and DIS systems. Our library of Automotive Waveforms contains example waveforms captured using an automotive oscilloscope and the PP178.

S-hook (MI168)

This small but essential accessory makes it easy to keep all those test leads tidy in the engine bay.

The S-hook is about 100 mm (4 in) long and coated in plastic and rubber to protect the vehicle's paintwork and your cables. Hook one end underneath the bonnet or hood, and use the other end to hang a bundle of cables up to about 25 mm (1 in) thick.
