8.7 Configuring events
An event occurs if the real-time value of a user-specified process variable varies above or below a
user-specified value, or inside or outside a user-specified range.
Events can be used to initiate specific transmitter actions. Possible actions include:
• Start zero
• Reset mass total
• Reset volume total
• Reset gas standard volume total
• Reset all totalizers
• Start/stop all totalizers
Up to five events can be configured. You can define more than one event on a single process variable
if desired.
You can configure an event to initiate multiple actions, e.g., you can configure Event 1 to reset both
the mass total and the volume total.
