Just got a great new DMM

do you know if it will measure peak inrush? can you show its output for harmonic distortion?
Yes (probably), and no...
This is a fast, high-resolution meter... The spec' sheet says it has a 4kHz (max, analog) sampling rate which, in most cases, should be fast enough. Sadly however, the mobile app' does not currently offer a "peak hold" button (although It would be great to have this feature in a future version!) . I haven't yet used the data logging tool, but it is my understanding that all data is buffered and then logged to the microSD card at a max of around 300Hz which means that for your average inrush (eg. the A/C compressor starting) of several cycles at 60Hz it should log it just fine, but possibly not for high freq'/short duration inrush events.
The Mooshimeter is not an oscilloscope and the app' doesn't have the ability to display freq' or THD. Interestingly, it can offer some o-scope-like functionality, for example here is a screen grab of the output waveform of my ProSine 2.0
Hey Mex', there's my handy DROK ac Volt meter :)
