The menu system
Update rate
The update rate
determines how often new results are available in the instrument.
The values in the Update Rate menu list indicate the time interval (in seconds)
between e very update of the results. Restrictions are placed on the number and
type of results permitted at faster update rates.
The range is 0.2 s to 2 s in 0.1 s increments, where 0.5 is the default value.
With update rates below 0.5 seconds, the number of results that can be updated
at that rate is limited.

as DC offsets, in the measurement. Three options are available:

Off. When autozero is disabled the instrument uses the last autozero values.

feedback to indicate it has run.
