Page 10: True-Rms Measurements
True-rms Measurements For ac measurements most DMMs average the ac input signal and display the result as an estimated rms value. This average-responding method is accurate for sinusoidal waveforms, but can be very inaccurate for distorted waveforms. To ensure the most accurate measurements, always use a true-rms DMM when measuring ac voltage or ac current on circuits for the following kinds of applications: •... -
Page 11: Beeper Off
Beeper Off The beeper is an aural indicator to identify when the DMM is performing a function, making a range change, detecting a limit, and so on. To disable the beeper use the following procedure: 1. Set the Function Switch to OFF. 2. -
