I see a value around 4.6V, consistent with measuring the batteries (out of the device) with a voltmeter. So I can experimentally confirm what you point out in the spec. Olivier: I would strongly recommend putting in 3 good alkaline batteries to the console. This will let it keep recording data over power glitches. But there is some risk of leakage - perhaps that's why you are avoiding it. Without batteries, I wouldn't worry about the reported value. It must be an A/D converter that is mostly floating with various tiny leakage currents providing bias. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
