4.7.2.7. Number of Records
The DAS is capable of capturing several months worth of data, depending on the
configuration. Every additional data channel, parameter, number of samples setting etc.
will reduce the maximum amount of data points somewhat. In general, however, the
maximum data capacity is divided amongst all channels (max: 20) and parameters (max:
50 per channel).
The DAS will check the amount of available data space and prevent the user from
specifying too many records at any given point. If, for example, the DAS memory space
can accommodate 375 more data records, the ENTR key will disappear when trying to
specify more than that number of records. This check for memory space may also make
an upload of an DAS configuration with APICOM or a Terminal program fail, if the
combined number of records would be exceeded. In this case, it is suggested to either
try from the front panel what the maximum number of records can be or use trial-and-
error in designing the DAS script or calculate the number of records using the DAS or
APICOM manuals. To set the number of records for one channel from the front panel,
follow the instruction shown in section 4.7.2.2 then press.
