![]() you can view the waveform signal 20KHz within.............. i'll pass.
i will wait until they update bandwidth to 2MHZ or 20MHZ. Last edited by capwizard; 01-20-2019 at 07:58 PM.. |

![]() Yeah I don't get the point of that feature, its the sort of thing you can do with a laptop and free software using the sound card if I recall. Well assuming you have the aforementioned laptop, analogue scopes can be had very cheaply now as well.

![]() the point of the feature is to see if the power is stable, or if it's being effected by something.
it's actually very good in some situations. |

I would like to have my next meter with another future is data logging that's what I've been searching for a cheaper and easy to use one. Any suggestion? Datalogging with a Multimeter https://www.norwegiancreations.com/2...-a-multimeter/ Last edited by capwizard; 01-22-2019 at 09:03 AM.. |

![]() no, not logging.
if you put a standard meter on a car supply, it will say 12-14v but if you put a meter with a waveform display you can see if the alternator is failing because you can see the dips between the 3 phases. dc is not always a flat-line, even if you want it to be! btw, i have a 22000count meter with a serial port - it's not the same thing.

But in general the output of an alternator is very noisy to being with any way but the wave form output would be different

![]() sort-of,
the alternator is a rectified (but not smoothed) 3phase generator. the dips in the output should be evenly spaced, if not then a diode or winding may be bad. |
