Logging and Recording Capacity

Data and Event Logging (9330 and 9350)

The standard memory capacity for both meters is 304 kilobytes of non-volatile memory. This is enough memory to log 16 parameters every 15 minutes for 30 days. However, by default the meter is set for a log depth of 930, which is enough for 9 days. Use the following equation to help determine different variations on this example:

each record consumes = ((number of parameters * 6) + 8)

Waveform Recording (9350)

The meter can simultaneously capture events on all channels to a maximum of 48 cycles each. To calculate the waveform memory usage use the following formula:

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

See the following table.

Format	Memory Usage	Page Usage
16 x 22	1024 x M1	1 x M
16 x 48	2048 x M	2 x M
16 x 72	3072 x M	3 x M
16 x 96	4096 x M	4 x M
32 x 12	1024 x M	1 x M
32 x 26	2048 x M	2 x M
32 x 40	3072 x M	3 x M
32 x 54	4096 x M	4 x M
64 x 14	2048 x M	2 x M
64 x 28	4096 x M	4 x M
128 x 14	4096 x M	4 x M

1M = Recorder depth

NOTE

Round up to the next kilobyte (1024 bytes) after each of the above calculations.
