I’ve found that there seems to be a roughly -0.8nA current source on the Ω and V input on the 1.2V DC range, causing stray readings whilst the meter is otherwise disconnected. A set of screenshots with the Mooshimeter sitting in a metal pan can be found at https://drive.google.com/folderview?id=0B-FoX5xGwRvKejBvT1I5T19wZTQ&usp=drive_web
Is this expected behaviour?The issue shows up on both Android and iOS with firmware 1418004830.
Hi Peter –
That’s within tolerance. The Ω input is floating, as is the V input when in 1.2V range, but there are protection and amplifier circuits attached to those inputs that have a little bit of leakage.
Is this acceptable for your application?

PS. Pan-frying the Mooshimeter makes it ineligible for return ;)
That explanation makes sense. It shouldn’t present a problem for me.
The frying pan was solely to provide a groundplane – I found that waving my hands (or the leads) around the Mooshimeter caused spikes in the readings.
