the MicroMMAC-T was last started up (Total), counted during the last polling
interval (Delta), or accumulated from zero at a user-defined point (Cumulative).

Set the time interval to update information (from 1 second to 23 hours, 59
minutes, 59 seconds) by using the clock symbol at the bottom of the window. See
Setting the Statistics Poll Interval , page 3-3 , for details.
