Hi all,
So I've been looking for an affordable sinad meter for awhile now and found this one on flea bay. I've been trying to locate documentation for it online but have searched everywhere to no avail. I'm mostly interested in it's calibration procedure. It appears similar to the Sinadder and I wonder if the same calibration would work. It had three tuning pots on the board just like the Sinadder but I'm a newbie and without the actual Protronix manual I am a bit nervous to just randomly guessing what to turn. The other thing that I'm unsure about is that it has a sticker on the back of the unit that says connector is 220v but the seller said he was testing it on 110v. I don't want to fry it with 220v if I'm not sure that's what it needs. Can I trust the sticker that it is actually 220v? Again, my apologies, as I'm new to all this and trying to learn as I go. Has anyone ever seen one of these? Any info at all would be greatly appreciated. It looks to be of good build quality and I'd love to be able to put it to use to tune recievers. 73's
