NetScan User’s Manual General Inform at ion and Specifications 3-5
Scan Interval:
• Absolute time between scans (hh:mm:ss.t); min = 00:00:00.0,
max = 99:59:59.9. Note: Specifying a value of 00:00:00.0 results in no delay
between channel scans.

available in single channel burst mode.
Time Stamp:
• Available for each scan group and for each channel’s high, low, and last
parameters.
Time Format:
• Relative time (hh:mm:ss.mil), absolute time (hh:mm:ss.mil) or absolute
date and time (dd/mm/yy hh:mm:ss.mil). Not available in single channel
burst mode.
Alarm Stamp:
• Available for each scan group. Not available in single channel burst mode.
