Selecting Scan Interval
The scan interval is the period between starts of measurement scans. The resolution of
the scan interval is one second; the maximum scan interval is 9 hours: 99 minutes: 99
seconds. The format of the scan interval is x:xx:xx; 1:30:45 translates to 1 hour, 30
minutes and 45 seconds.
If scan interval of "0:00:00" is specified, continuous scanning will occur when the Scan
function is activated. If more than a few seconds are required to scan all defined
channels, a short scan interval (a few seconds) effectively becomes continuous scanning.
If the Monitor function is turned on when the instrument is continuously scanning, a
Monitor channel measurement is still taken between each scan.
Table 3-10 illustrates the button sequence used for setting scan interval. If necessary,
refer to "Entering and Changing Numeric Values" for a more detailed description of the
number editing technique used here.

Selecting the Measurement Rate
The slow measurement rate provides the highest accuracy and resolution. A fast rate can
be selected, but keep in mind that fast rate provides one less digit of resolution than does
slow rate. Measurement rate selection is illustrated in Table 3-11.
