The digital multimeter, DMM, is one of the most common items of test equipment used in the electronics industry today. While there are many other items of test equipment that are available, the multimeter is able to provide excellent readings of the basic measurements of amps, volts and ohms.
Here are the basics of the rules, which will apply to drones weighing fewer than 55 pounds: pilots will have to pass a knowledge test (but not a practical test) to get a newly developed drone operator license and will have to be vetted by the TSA.
The new rules will also limit flights to the pilot's line of sight and altitude to 400-feet. The really bad news is that these rules won't just apply for big Predator-sized drones. They'll apply to any unmanned aircraft under 55 pounds. That would include small, affordable, easy-to-fly drones like the DJI Phantom line and the new Parrot Bebop.
