(...) It doesn't matter. DMM's are not good at measuring pulsed signals. (unless you have one of the more expensive true-RMS meters which can calculate the average of a non-sinusoidal waveform. You really need an oscilloscope for this. (...) It will (...) (22 years ago, 30-Dec-02, to lugnet.org.ca.rtltoronto)
