Fine Tuning Over Condition Monitoring
If you want to fine-tune over condition monitoring, the only setup registers you
should change are SusUntlON and SusUntlOFF.
should change are SusUntlON and SusUntlOFF.
SusUntlON determines how long the modules wait after an over condition is
detected before reporting it. This gives the monitored value a short period to
correct itself before the event is registered with the module, so that very brief over
conditions are ignored. Similarly, SusUntlOFF is the amount of time a normal
value must be present before the module considers normal operation to be
restored. Both SusUntlON and SusUntlOFF values are entered in seconds (the
default value for both is 30 seconds).

Meter Clock Configuration
The Clock module controls the meter’s internal clock which provides timestamps
for data logged by the device. The clock needs to be configured properly to ensure
that logged data has accurate timestamp information. The Clock module also
receives the time synchronization signals sent to it by the workstation running
ION software, updating the device’s clock when required.

The setup registers in the Clock module specify timezone and Daylight Savings
