Clip type DC current probes??

Sep 03, 2005 2 Replies

I am a Sunday car mechanic. :-)



What types of probes could I use to measure (to a few percent) the various currents in a car. I think they vary from about 20 mA (clock, alarm) to 500 A (starter). A single probe cannot have a 25000 to 1 dynamic range of course.



I already have a Fluke 87 digital multimeter and a shunt. I am looking for Hall effect probes that I could clip around wires to measure the current. I neither want to disconnect or, worse, cut wires.



What are your suggestions?



Thank you very much in advance.

isn't bad, though it only goes down to about 1/2 amp, and up to

400A...

If you can wrap the wire thru the clamp several times, it may allow you to measure lower currents.
