Hey all:
Got my new USB Voltage Meter (with OLED display) along with some other goodies today (yay). But when I went to test out the USB voltage meter in line with a device it failed to show anything other than the "Welcome" boot screen. I watched the New Products video from 19 August 2015, which shows Limor using this awesome product by itself and in line with a load, so I don't think I'm using it wrong and she didn't say that there was any hokey-pokey needed to get it to work. I checked the product card that came in the carrier box and there's nothing special written on it concerning a process - just plug and play. I've hooked it up using different power sources, loads and cables, and all I get is the "Welcome" screen and then it goes dark. The only thing it does is that it passes a charge to any attached load - just no display to show me details about the voltage, amps or watts - nadda. No error messages to report either.
Also, I tried pressing the button on the back (the one that resets stored readings) just for good measure - didn't budge : (.
Taking a photo is a no go. I don't have a camera that will shoot as fast as the screen clears (and I don't have an extra hand to snap a pic while holding the camera and plugging in the unit). So I have the following link showing a brief video:

Hi Support Team,
I recently received my USB voltage meter: http://www.adafruit.com/products/2690 and I'm having the same issue as squidly1.
In my case the meter remains stuck on the welcome screen after power-up each time I insert it into a USB port. This happens with or without a test USB device connected to the meter. I pressed the display reverse button on the back of the meter (momentarily and press-hold) while it was powered up, but it had no effect. The display simply shows "WELCOME" and then hangs indefinitely. The meter will allow a connected device to charge, but nothing appears on the display except the welcome message.
Thanks in advance,
-Rick

Re: USB Voltage Meter (OLED version) no workie
The photo shows the original meter (top) and the replacement meter (bottom) connected to my laptop. The original meter still refuses to move beyond the welcome screen. The replacement meter initially worked, but now refuses to display anything at all. I can’t remember ever having such poor luck with a new device. Do you have any recommendations?
Thanks,
Rick

At this point I'm afraid all we can do is offer a refund. It's possible that something in the operating environment is contributing to the failures.
Send a note containing a link to this page and your order to [email protected]. The folks there will arrange a refund for the cost of the meter.
