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)
