Amp Clamp Overload - Is it Possible?

Got this
https://www.kleintools.com/catalog/clamp-meters/acdc-digital-clamp-meter-auto-ranging-400-amp
meter to measure DC current on automobile as it's a pain to worry about the fuse popping on a regular multimeter inline.
Is it possible to damage/destroy an amp clamp meter by measuring too high of a current in a setting? I'm not quite sure how Hall effect sensors are designed.
I'm going to do a 10 turn wrap cord around the clamp to increase it's accuracy in it's lower ranges to measure parasitic drain but don't want to run into any problems as I plug fuses back in because the current can spike.

I don't think you can damage the sensor with a magnetic field but you can certainly magnetize the clamp and it will need degaussing afterwards.

With most of the clamp-meters I have used, when measuring DC current you have to zero the meter because of residual magnetism in the clamp after a reading. The zero function is part of the meter.
