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. 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 cause the upload of an iDAS configuration with APICOM or a terminal program to 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.

To set the NUMBER OF RECORDS, follow the instruction shown in Section 7.1.5 then press:
