Thanks,
I must have taken it out of automatic (thinking that the “A” button meant AMPS). The Android UI is really very different from any DMM I’ve ever seen so without documentation it’s pretty raw.

Also it takes a really long time for the AC reading to stabilize (now at a healty 122.x volts) At 4khz, a 256 sample buffer should fill in 0.064 seconds so I don’t see why it takes so long to get close.

Final whine: on graph mode the AC voltage seems to be “zerod” about some kind of average and then because of autoranging you just get a waveform which seems to indicate the last bit hunting up and down. Bottom line with current software Meter is useless for monitoring wall voltage trend.
