Low Amp clamp for scope

    Im looking into purchasing a low current amp clamp for a labscope I currently use and was wondering if anyone might have some insight as to which one to get or if someone can point me in the right direction please. I will be using it to diagnose injector and coil circuits as well as doing relative compression tests etc.

This is the one I use. I've had a few, I trust this one more some of the others I had.
It turns off automatically, which can mess you up if you're not paying attention when it happens, but it's pretty accurate.

Also would you recommend a low current or a high current amp clamp lets say for doing a relative compression check and when conducting one what settings would you set the scope to for using the clamp?

Definitely recommend a high amp probe for relative compression.

You can do relative compression with the right low amp probe, but it's a pain. You're limited by the cranking current of the engine you're testing. The Snap-On low amp probe, for example, will max out at 200A. That means you can test most four and six cylinder engines. But some V8's will draw over 200A during cranking, and you won't see anything. Getting the small jaws of a low amp probe around the right battery cable can be a fight, too.

Most high amp probes will use a 1mV/1A scale. So, if your scope shows 150mV, you're measuring 150A. Most gas engines draw somewhere between 100-300A during steady cranking, so a 500mV or 1.0V scale will work well. Some scopes (Pico, Autel) have a preset probe at this conversion scale, some others (Snap-On) do not.

The time base will depend heavily on how much detail you're looking for, and what scope your using.

Perfect I am gonna get the high amp as well I appreciate the insight most definitely

I have had good results with the AES or aeswave low amp clamp its highly accurate and cost is not too bad at $99.  You can get it with bnc or banana jacks.   www.aeswave.com/Current-Probe-Low-range-with-BNC-p9500.html   aeswave also stands behind their products and offers support.
