Teledyne 9110T instruction manual Editing the Number of Records

Model 9110T NOx Analyzer Data Acquisition System (DAS) and APICOM

temporarily stores them in volatile memory as part of the REPORT PERIOD currently active at the time of restart. At the end of this REPORT PERIOD, only the sample readings taken since the instrument was turned back on will be included in any AVG, SDEV, MIN or MAX calculation.

The STORE NUM SAMPLES feature will also report the number of sample readings taken since the instrument was restarted.

7.1.3.6. Editing the Number of Records

The number of data records in the DAS is limited to about a cumulative one million data points in all channels (one megabyte of space on the DOM). However, the actual number of records is also limited by the total number of parameters and channels and other settings in the DAS 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 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 button will disappear when trying to specify more than that number of records. This check for memory space may also make an upload of a 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 to determine what the maximum number of records available is using the front panel interface 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, follow the instruction shown in Section 7.1.3 then press:
