20 Power Availability
The ION 8400 and ION 8500 meters come pre-configured with a power availability
framework that provides reliability measurements using “number of nines”
calculations.
NOTE
While the Availability Framework is pre-configured, the operation of this framework requires the correct
configuration of the Sag/Swell module according to your meter’s power supply and operating ranges.
See “Sag/Swell Module Configuration” on page 200. See also the
ION Reference
for detailed
descriptions of this module.
