7.1.5.6. Editing the Number of Records
The number of data records in the iDAS is limited to about a cumulative one million data points in all channels
(one megabyte of space on the disk-on-chip). However, the actual number of records is also limited by the total
number of parameters and channels and other settings in the iDAS 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 iDAS 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 iDAS 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 iDAS 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 to determine what the maximum
number of records available is using the front panel interface or use trial-and-error in designing the iDAS script or
calculate the number of records using the DAS or APICOM manuals.
