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.
Thankfully, it turns out that the FAA will not require drone pilots to get a private or commercial pilots license, and operators will not have to pass a medical exam. As expected, commercial drones will only be allowed to fly under 500 feet and no faster than 100 mph. Drones will have to be registered with the FAA. Flights over people are prohibited and visibility has to be over 3 miles. Drones can fly autonomously, but all of the other regulations (line of sight, maximum height, etc.) still apply and the pilot has to be able to take manual control at all times.
