I just ran across this new multimeter
What I thought was neat was it gives voltage and frequency at the same time.
Has anyone used this meter?
What are your thoughts?
Is the graphic display useful?
With an analog bandwidth of 20KHz, the waveform plotting feature is very limited and not useful for measuring much inside a pinball machine.
Digital signals generally are switching at 1MHz or higher rates.
The product description shows 5 Hz to 5 MHz. But I saw on a Youtube review that it wouldn't go over 1 MHz.
I’m pretty sure that only refers to the frequency counter function. For the waveform plotter the analog bandwidth is only 20KHz and it samples at 200KHz (10x oversampling).
A frequency counter just requires a comparator to tell how often a signal is toggling above and below it’s mean.
The waveform plotter actually require an ADC and capture buffer and has different specifications than a frequency counter.
Most reviews of this multimeter complain the graphics has no gradicule. You can change the time base but you still don't know what you are looking at.
I already have a nice bench oscilloscope so that wouldn't be it's primary function.
It just looked neat and the price was good. I guess I was hoping someone would say it's a great tool to have and they use it all the time. I guess it's just a gimmick.
Thanks for the input. Saves me a few bucks.
