for all you tool tarts out there.

[telectrix]

just received this item. multimeter with waveform graph. unbelievably only £47 inc. shippling. what will them chinese get up to next?

 

[Spoon]

Are you going to do a 'review' on it?
Bung it on a dimmer switch and see how accurate the graph is.

 

[telectrix]

will give it a try sometime soon. expect to see a funny waveform from a dimmer.

Like it Have you got the additional nipple-clips? ....we'd like to see your heart beat,in wave form...

 

[buzzlightyear]

same thing has this ,LOL.

Does make the markup on "approved hearing aids"
look a bit excessive --Eh...What...
(it's a very different world of electronics today!)

Used stolen credit card I bet.......... if it was me I would have ordered up to the CC limit, tsk......

You know that's just a sticker where the screen is supposed to be

£47 ... £47 ???
That's 31 bottles of OP you've wasted on something that looks like an 8-bit gaming machine from the early 80s.
Get a grip man!!!

ok, so this is the output waveform from a 400watt dimmer supplying a 60 watt load at approx, 75% full. and @darkwood. it's not a sticker. .

Let us know your top score and we’ll see if we can beat it!

The 173v rms?
From the increments can you work out peak to peak.
Does it show any spikes at switch on?

 

[telectrix]

still playing with it. not worked it all out yet. obviously, not as accurate as a calibrated scope. can expand or reduce the timebase. more play tomorrow after i've fixed the oven, mown the lawn, sorted the dogs and ducks out etc., etc.

That is just too good !!!

Vrms = 0.3535 * Vpp

Cool, but I'll stick with my Megger AVO

 

[telectrix]

which model> i have a later model 8 and an avo megger digital thing, forget the model.

 

[telectrix]

just a techybit for trainees.


the green is the input waveform as expected, and is passed straight through the dimmer when on non-dimmed. the red section is cut trailing edge as preferred by LEDs. it's so-called because the dimmer electronics cut the trailing edge, as opposed to the leading edge.

 

[telectrix]

and leading edge cut.

Is that done with your new hand held scope?
