I don’t know if I measured a voltage i shouldn’t have or if I measured the ohms of a hot circuit while working on my jeep, but my meter now has a problem. It reads voltages too high and rapidly drops those voltages over a few minutes time until it seems to settle close to the correct voltage. I’m comparing to known DC power supply and battery voltages as well as a sun equipment DMM-1230. The overshoot changes depending on how high of voltage with higher voltages giving a higher overshoot and lower ones ging less overshoot. Did I blow up a capacitor or something? This is the most I have spent on a multimeter, and I really think I should have stuck with the SUN or even those shitty harbor freight meters they give away for free.
Hi Chace,
I’ve never seen the behavior you’re referring to, sorry it’s giving you trouble. Do you have any more info on what you were doing when it first started to fail? Also when did you get the meter? Were you a crowdfunding backer or bought later?
If you’d like to set up an exchange please email hello@moosh.im. This is still quite a new product so when failed units come up I take them seriously.

~JamesI think it must have been when measuring resistance on a potentially hot 12v line. I was trying to find a short, ignition was off but battery still attached so it could easily be my fault. If you want to take a look at it I can mail it to you. I have the sun equipment to use in its place for now.
Oh and I forgot to answer your other question. I was not a backer, I bought mine after the online store appeared and after pre orders were over.
Thanks Chace,
If the meter was behaving properly before connecting the resistance terminal to a hot line, then I agree that’s probably the event that did it. However the meter should be protected against overload on the Ω terminal.
When I was saying mail exchange, I meant to mail you a replacement. Please let me know if you’re interested.

~JamesJames,
I’v having the same issue. My batteries died and I replaced them. It powers up just fine but I get negative voltage readings whether it is connected to a battery or not. I’ve reset it, rebooted my iPhone and reinstall the app and the same problem persists. I can connect just fine but the readings are all over the place.
