Data Logging Menu and Downloading Data
In the METER mode, the Model 1140A has the capability to log, store, display, and download
10,000 data points, each of which contains a date, time, and the data itself. By going to the
DATA LOGGING MENU, the user can set the time interval between data points and start logging
data. Once data has been stored, the user can view the data on-screen and download the data in
various formats.
