  • Page 3 ® USE TRUE RMS WHEN MEASURING AC WAVEFORMS The waveforms on today’s AC power lines are anything but clean. Electronic equipment such as office computers, with their switching power supplies, produce harmonics that distort power-line waveforms. These distortions make measuring AC voltage inaccurate when you use an averaging DMM.
