Alarms
Number of alarms Up to four alarms (level) for each measurement channels.
Alarm types High limit (H), low limit (L), delay high limit (T), delay low limit (t). The alarm symbol is shown in parentheses.
Alarm delay time of delay high and low limit alarms (can be set for each channel, common within a
channel) See section 12.2
Hysteresis Applied to high limit alarm and low limit alarm.
Hysteresis range: Approx. 0.0% to 1.0% of the recording span (0.1% steps)
Miscellaneous See section 12.2.
Display See section 12.4.
