I have used the following DMM to measure frequency Fluke 87V, 189, 287, 289, 45 and all can measure pulses. Although the kind of pulses I have are either 5V or 12V or 24V (not 17V but I don't think 17V would make a difference). And yes they are all square wave pulses. --- End quote --- There are differences in how they trig, some requires a zero crossing, some do not. --- End quote --- All of the signals I mentioned are not zero crossing. They are 0 to 5, 12 or 24V pulses. |
