The TA234 probe is a 30 A current clamp. The extended measuring jaws allow measurement in a confined space. When measuring DC, a simple thumbwheel on the probe allows zero adjustment.
This current clamp is ideally suited for use with PicoScope oscilloscopes and features additional screening to reduce noise pickup.

Typical Uses
With a 20 mm extended jaw the TA234 low amps current clamp is ideal for parasitic drain measurements without the need for battery cable disconnection. The clamp also boasts extreme accuracy from 5 mA through to 30 A DC with reduced noise levels so ensuring greater resolution for very low current applications, including:
Parasitic drain measurements
Petrol and diesel injector operation
Solenoid testing
Throttle motor functions
EGR actuator testing
Broadband 02 sensor testing (in conjunction with current multiplier)
