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.
Cu10, Cu25 RTD Input (/N1)

3 Legs Isolated RTD (/N2)
Item Specfcatons
Input terminal isolation Applies to the dot model.
The RTD input terminals are isolated between channels (on the standard dot model, input
terminal b are common to all channels)
