85 3.2 AFM readings

[85SOK]

Hello All,

Checked the AFM settings today on the old girl (3.2) using the method commonly suggested here. Ran her up to normal operating temp, disconnected O2 sensor,
connected Digi MM + (red) to O2 sensor - (blk) to grnd.

Readings were a constant sweep from 0.5v to 0.6v did not vary at all. 0.5v-0.6v on and on. Is this good, bad, normal or should it be sweeping more?

Thanks for your input, time and help!
