Setting the Scan Interval
Perform the procedure in Figure 2-11 to set the time between starts of measurement
scans. In preparation, the instrument must be in the inactive mode (not scanning or
monitoring). To exit at any time (changes not saved), press the C key. The scanning
interval format is HOURS:MINUTES:SECONDS. The minimum is 0:00:00 (continuous
scanning [default]); the maximum is 9:99:99 (9 hours, 99 minutes, 99 seconds). The scan
interval is divided into two portions: the measurement interval when measurements are
actually taken, and the time-out interval that completes the overall scan duration. For
example, if 10 channels can be measured in 8 seconds, and the scanning interval is set
for 30 seconds, the first 8 seconds are used for measurement, while the remaining 22
seconds are used to time out. If the scanning interval is set to less than the measurement
rate, the effect is continuous scanning. For example, if 10 channels can be measured in 8
seconds and the scanning interval is set for 5 seconds, scanning is continuous. To speed
up the measurement rate, refer to Figure 2-12.

Setting the Scan Interval. Press the INTVL
(Interval) key to access the scan time menu. The
format is HOURS:MINUTES:SECONDS. Press
the up/down and left/right arrow keys to select
and configure each column in the menu. For
example, a scan interval of 1 hour, 25 minutes,
and 33 seconds would be formatted as 1:25:33.
The column being configured will have a bright
display. When the display shows the desired
interval, press the ENTER key.
