	The multimeter can also measure RMS current. To do this, you must have the probes set up correctly to measure current and the dial should be set to one of the current modes (see above). The current mode defaults to AC mode, so it with report the RMS current through the multimeter automatically (recall we had to press the yellow 2nd button to read DC currents earlier). If you press the yellow 2nd button twice (so that "Hz" appears on the display), you will be able to measure the frequency of the current.		The multimeter can also measure RMS current.

	Because of the limitations on low-end current measurements, the clamp meter is mostly useful only for high-voltage power source. It is also useful as it does not require interacting with the high voltage (and often high current) electricity directly.
