[Available memory]
The remaining capacity of the memory, into which the data is recorded, is indicated by the bar graph
(50 steps). The number of data to be recorded to this unit may vary depending on the recording mode,
that is, log mode or tag mode.
z
Log mode
In the log mode, the data can be recorded until the total number of data recorded to 20 logs reaches
40000.
One number of data corresponds to the data volume used for one recording at one channel.
Therefore, the number of data to be recorded may vary depending on the number of channels to be
used.
The available recording cycles is calculated from the following formula.
Available recording cycles [cycles]
=
Free memory capacity [data]
÷
Number of channels in use
[ch]
The available recording time is calculated from the following formula.

[Example]
If the free memory capacity is “1000”, all of four channels are used, and data is recorded at intervals of
5 min., the available recording time is 1250 min.

z
Tag mode
In the tag mode, the data can be recorded until the total number of data recorded to 20 tags reaches
10000.
One number of data corresponds to the data volume used for one recording at one channel.
However, the number of data to be consumed may vary depending on the number of channels in use.
