Model 6517A Getting Started Manual

Buffer (Data Store)

The Model 6517A has a buffer that can store from one to over 15,000 readings. The actual
number of readings that can be stored in the buffer depends on how many optional data
elements are included for each reading (see Table 2-22 in the User's manual).
The basic data elements include the reading, units, reading #, and status (overflow or
underflow). In addition to these items, recalled data also includes statistical information
such as minimum, maximum, average, and standard deviation, which are part of the
NEXT displays (see Section 1, "Multiple Displays").
Optional data elements include timestamp, humidity, external temperature, channel num-
ber (for scanning) and the V-Source level.

Storing readings

The following procedure to store readings uses a typical data store configuration: a user-
defined number of readings will be stored in the buffer (fill-and-stop). All aspects of data
store configuration and operation are detailed in Section 2 of the User's Manual.
