How can a clamp-meter measure AC- and DC-current without interrupting the circuit?

In AC-mode it works as a current-transformer.
In DC-Mode a hall-effect sensor is used.
A DC clamp-meter is useful for the electronic hobbyists-lab only if it goes down to 1mA resolution or better.

The poor-man´s Infrared Imaging-Camera :-)
Roger explains how an electronic Infrared-Thermometer (or Pyrometer) works and what traps there are when taking measurements with them.
Why is a high Spot-to-Distance ratio of the IR-lens important?
What is the optical parallax of the laser-pointer?
What is the emissivity-factor and when can it give false measurements?
