Power Meter identification « on: 2017-08-13, 06:22:08 »

Does anyone know the exact make and model of this power meter that Nelson Rocha is using in this video?

http://www.youtube.com/watch?v=KAtRv6PneNs

Note especially the last appearance of the "overload" message and the "0 Watts" indication towards the end of the video at about 8:10 --
while the vacuum cleaner is plugged directly into the meter and _not_ through the "white box". 


I think this video shows not an "electron trap" but rather a "sucker trap".

Yes ;)

I say forget about meters!... add a 1 or 2 Amp fuse to the line cord (per box) and if he can still power the vacuum without the fuse blowing, then it would be a device to seriously consider.

Thanks for that link to the manual.  Reading the manual, I can't quite tell if I've misinterpreted the "overload" messages that appear in the video, or not. Nevertheless it's clear from the experiences of others that meters of that general type are very easy to fool.

Luc's suggested fuse test would not be so easy to fool, though. Will we see such a test performed?

Hi Tk

It looks like the overload function is settable for either Amps or Watts and can be set to a user value, if the measured Amps or Watts exceeds the set value then Overload will flash on the screen, maybe if the overload mode is set then overload will not flash if the value is not exceeded but remain constant to say it is in Overload Alarm mode.

Regards
Peter
