External ION Events

Some events are not produced by a specific module; they are generated internally by the meter. These events and their associated priority levels are shown in the table below.

Event Group	Description	Priority Number
	Factory initialize performed
	Firmware or memory upgrade performed
	Meter power-up or power-down
Warning	Internal modem not responding or modem recovered	30
	Battery low
	Telnet or serial terminal locked out
	Security disabled or enabled
Failure	Communications fail to allocate required memory	255

Logging and Recording Capacity

The meter provides both data and event logs, but the amount of memory required to store these logs depends on the number of parameters being logged and the frequency with which these parameters are logged. The following equation can help determine the amount of memory required to store data and event logs:

each record consumes (in Bytes) = ((number of parameters * 5) + 8)

The meter can also perform waveform recording. It can simultaneously capture events on all channels to a maximum of 96 cycles each. To calculate the waveform memory usage use the following formula:

waveform memory usage (in Bytes) = (2*(number of samples per cycle) + 10)*(number of cycles in waveform) + 30

NOTE

Round up to the next kilobyte after each of the above calculations.
