I'm curious as to how DC clamp ons work? I thought only AC would generate the requisite field?

Current passing though the wire creates a field. AC the field collapses and reverses as the current flow reverses. DC it is constant. Relays, solenoids work on DC field.
If you want to buy a tong meter you should invest in a decent one.
