Description
The TA473 current clamp is ideal for use with PicoScope automotive oscilloscopes for measuring currents between 10 mA and 60 A. This enables the PicoScope to display current waveforms for fuel injectors and fuel pumps.
The TA473 has a specification superior to both the TA018 and TA234 bringing improved performance and diagnostic accuracy to the workshop. In common with the TA388, it is fitted with a PicoBNC+ interface. The clamp can be auto-configured by PicoScope software when it is 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 it is connected to the scope.
In use, there is no need to break into the circuit or disturb the isolation as the opening jaws simply clamp around the current-carrying conductor. No electrical contact is required.
These current clamps have been designed for use with PicoScope oscilloscopes and feature additional screening to reduce noise pickup. The Pico TA473 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.
Frequently Asked Questions
What can I measure with the 60A clamp?
The 60A current clamp is ideal for measuring injector current, fuel pump circuits, ignition coil primary current, sensor supply circuits, and charging system output. For higher-current measurements like starter motors and EV battery circuits, use the 2000A current clamp instead.
Is it compatible with my PicoScope?
Yes. The 60A clamp uses the PicoBNC+ interface with automatic probe recognition. It works with the 4425A and 4823 oscilloscopes. PicoScope 7 software configures the correct current scaling automatically. Full specifications at picoauto.com.
Which kits include this clamp?
The 60A clamp is included in the standard kit, advanced kit, and master kit. It can also be purchased separately for any PicoBNC+ oscilloscope.
