Status
Brings up the Alarm Status box. The Alarm Status box shows the current state of each alarm. The alarm state
appears as either a “1” or “0”, the “1” being digital High, and the “0” being digital Low (0). A one-for-one
correlation between the alarm number and channel can only occur if each channel of a 32 channel [or less]
system is assigned to a dedicated alarm number.
Log configuration
Alarm logging is a feature of ChartView Plus only. Alarm Logging allows you to monitor the Alarm states of the
instrument, and save selected information to a file whenever any of the states change.
Alarm logging is implemented by periodically polling the instrument; the time interval between polls
is about one second. With this in mind, be aware any event that could trigger an alarm [
lasting
one second or less ], could be missed and not logged.
