Have you used the forums search function?
IMO it has been debated to the moon and back, which current clamps are suited for which use cases.
Would be the best place for you to start.
I found nobody talking about using a current clamp to trace a short circuit.
If your power supply has a latch-off function, indeed it could be annoying to trace a short circuit in wires. If you cannot disconnect the wires to eliminate the issue, then a clamp might work. I have the UT-210E that I bough for about 30 USD years ago, somehow it's now cost twice as much.
In my experience you get maybe 600mA residual magnetic field/earth magnetic field on the lowest range (2A DC), that you need to zero out, and then move the meter as little as possible.
