This really isn't a technical question, but I am posting this here because I don't see any other means of contacting Adafruit about this. Please let me know if I should use another means of getting info on this.
About 2 months ago I ordered and received the $25 multi meter, labeled, ET-1700. I can't really state the brand name as it is labeled using one of those fancy fonts that nobody can really understand (Minipa?).
I went to use it for the first time today to simply test continuity/resistance of a SECO-LARM garage door magnetic sensor - but I never got that far.
Out of 40 years of habit, I turned the dial from OFF to the resistance/diode-check. The LCD screen lit up, I assumed all was fine. I did not study the character output but the larger digit(s) did read 0. I touched the meter leads together, and expected a beep/buzz, but I heard nothing. I looked at the screen and opened the leads and touched them again, and nothing changed, still a 0 on the LCD. Out of habit, I turned the dial to OFF and then back to the resistance test and after about 5 more seconds, the screen went dead. I really can't say what else the screen was showing because it went dead before I could look at the details. The larger digits were showing 0, but I am not sure about the other smaller characters that did appear. The screen wasn't gibberish, it was just static, and then went dead.
This would seem like a battery issue, as a resistance/continuity test is about as simple as it can get. Is it common for these items to ship with dead batteries? I will open it up and check and change the battery, if that doesn't work I will toss it. I just want to get some input before I open it up.
