content: I'm hoping you could help me since I had no luck on ebay:I'm looking for either a combined or two separate panel meters to put in my variable isolation transformer. The built-in meters are really shitty. In principlethis meterwould be great but it doesn't go down to 0V.Requirements:- digital- 0-300 VAC- 0-3 A- Resolution <=1% + 0.5V- Readable in the Dark- Same supply voltage for both meters- Price for both incl. shipping < $40Believe it or not, everything I saw on ebay didn't meet my criteria.

content: I suspect the reason it does not go down to 0 volt is because it powers itself from the measured line.Which means many cheap & simple ones will probably have the same issue.The reason it does not go down to 0 amps is because it is a coil measure, not even hall, but ac inductance. Apart from not going down under 1 Amp, you should assume that while it may read out at 0.1 precision, it is probably only 0.5A precise. Or even less.If you want reliable current, you should consider a shunt. But they often are not for line ac voltages.EDIT: not relevant, but while idly browsing for you (waiting at work) I ran intothis multimeter21 sold even? Surely that is a typo in the price?

content: I have two of those meters.They are not good, but they are not bad. If you just want to know if something is hot, or is broken, they will do fine and are well worth the 2.50. But up to UKP 100 ?!?!?? Buy mine please, you'll get both of them !Anyway:How about this:http://www.ebay.com/itm/400646329700Consider putting a 1:10 resistor divider at the line voltageThough best search for a seller that has 99% at least, and does not try to hide the purchase price in the shipping cost.PS: I watched that "review". Its a joke right? I am asking because I am known to have a misaligned sense of humor, but this was sarcasm right? Just checking.

content: Ah!Yes, that makes sense. I was wondering. I know there is one born every minute, but 21 of them at that price.....
