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

Before the launch of this probe, we recommended the TA019 (600 A) for working on the starting and charging systems of petrol passenger cars and the PP253 (2000 A) clamp for high-compression diesel engines. The TA167 (200 A / 2000 A) covers both these applications in one probe with improved range and sensitivity, lower noise, and faster response.

The TA167 features a 200 A mode for better performance at lower currents and has an increased jaw size. It also features an auto power-down facility to save battery life when not in use (this feature can be disabled for battery drain/shutdown current testing).

Typical Uses

• The wide range of this clamp allows currents to be measured from under 1 amp right up to 2000 amps. It can therefore be used with a PicoScope for many applications including:
• Battery testing with PicoDiagnostics software
• Relative compression testing
• Starter motor testing
• Alternator output testing
• Hybrid and EV electric motor current

On the 200 A range the TA167 can also be used many applications where a "low amps" clamp would normally be required such as checking injector and ignition current.
