The fact that it's 2% of the measurement is key. If you were to measure 100 amps, you'd know that it's between 98 and 102 amps. Some meters are accurate to within 1% of the range.
Therefore, what does a clamp on ammeter do?
Clamp-on ammeter or simply 'clamp meter' is an instrument that is used to measure the current flowing through a conductor. An AC Clamp meter basically consists of a current transformer in its jaws, bar CT usually. Utilizing the principle of current transformer, the reading will be displayed.
Suitably, is a clamp meter better than a multimeter? A clamp meter is built to measure current; they can, however, measure other electrical fields like voltage and resistance. Multimeters provide a better resolution and accuracy than clamp meters, especially on functions such as frequency, resistance, and voltage.
Even if, how do you use an ammeter clamp?
How do you use a amp probe clamp?

What is a clamp meter? Clamps measure current. Probes measure voltage. Having a hinged jaw integrated into an electrical meter allows technicians to clamp the jaws around a wire, cable and other conductor at any point in an electrical system, then measure current in that circuit without disconnecting/deenergizing it.
