Since .814 Kohms = 814 ohms you should be able to answer your own question. Voltage doesnt go through wires in the sense of a flow. Current does go through wires similarly to water flowing through a pipe. The spelling is ohms -- not olms.
The multimeter has an autoranging circuit that decides which scale to use depending on what it sees. If 814 ohms is near the top of the "low" range, then the auto ranging circuit will switch to a "middle" range in order to avoid problems near either end of a measurement range.
