PicoBNC+ 2000 A AC/DC current clamp

The 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 TA388 has a specification to match our popular TA167 200A/2000A clamp but fitted with a PicoBNC+ interface. The clamp can be auto-configured by PicoScope software when 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 connected to the scope.

These current clamps have been designed for use with PicoScope oscilloscopes and feature additional screening to reduce noise pickup. The Pico TA388 current clamp can either be purchased as an accessory within one of our popular diagnostic kits or individually but requires a PicoScope featuring the PicoBNC+ such as the 4225A or 4425A.

Typical Uses

The wide range of this clamp allows currents from under 1 A right up to 2000 A to be measured. It can 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

The 2000 A clamp also features auto-ranging allowing the TA388 to be used many applications where a "low amps" clamp would normally be required such as checking injector and ignition current.
