Model 2700 Multimeter/Switch System User's Manual
For SCAN, the reading count also determines the number of scans to perform and is best
explained by an example. Assume there are 10 channels in the scan list (i.e., 101 through
110). If you set the reading count to 10 or less, one scan of the 10 channels will be
performed. If you set the reading count to any value from 11 to 20, two scans will be
performed. A reading count from 21 to 30 gives you three scans, and so on.
Timer interval (TIMER) — For the STEP function, the timer specifies the time delay
between scanned channels. For the SCAN function, the interval specifies the time delay
between scans. The timer starts when the scan is started. For SCAN, the next scan will not
start until the timer interval expires.
