Using a clamp meter

I got in the clamp meter which I ordered, and plan to go down to the marina tomorrow and do some troubleshooting on the electrical issues on the boat.

My first time to use a clamp meter (I only learned about them the other day, when I posted about my electrical problem). So I looked on the internet to see how to use it to measure amperage. And thought that I understood it.

But some postings which I have read on here recently have me puzzled, so I thought someone might take pity and enlighten me.

It was my impression that in order to measure amperage, the meter has to be clamped around only one conductor. But if I understand the posting which I read yesterday, someone was measuring the amperage on the shore power cable by just clamping around the entire cable. I may have misread that, but don't think I did.

So I am puzzled, which is nothing new.
