The 2000A/200A (TA167) heavy duty current clamp from Pico features additional screening to reduce noise pickup and uses advanced Hall Effect sensors for improved sensitivity and high external field rejection.
Use it for starter motor testing of commercial vehicles and large engine passenger cars.
Compared to the Pico PP266 (600A), and Pico PP253 (2000A) clamps, the TA167 has improved sensitivity, lower noise, faster response, an improved jaw size, and in the 200A mode the TA167 offers better performance at lower currents.
The TA167 uses a 9 V Alkaline battery and 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 (and other scopes) 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 for such as checking injector and ignition current.
