# Ultimeter {id=ultimeter_notes}

The Ultimeter driver operates the Ultimeter in Data Logger Mode, which results in sensor readings
every 1/2 second or so.

The Ultimeter driver ignores the maximum, minimum, and average values recorded by the station.

## Configuring with `weectl device` {id=ultimeter_configuration}

The Ultimeter stations cannot be configured with the utility
[`weectl device`](../utilities/weectl-device.md).

## Station data {id=ultimeter_data}

The following table shows which data are provided by the station hardware and which are calculated
by WeeWX.
