Resetting and Pausing Power Availability
The power availability framework allows the user to pause or reset its operation. 
The framework can be paused with ION software; resetting the framework can be 
performed via ION software or, in the case of the ION 7500 and ION 7600 meters, 
via the front panel settings. 
Resetting Availability with Vista
With Vista software, you can manually reset availability calculations. A meter is 
typically reset after installation to ensure valid time counts.
Availability calculations are reset with the Rst Avlty Stats (Reset Availability 
Statistics) External Pulse module, which can be accessed through the meter’s front 
panel or with Vista software.
To ensure correct availability calculations, do not reset during a Sag or Swell.
