Storing And Recalling Readings - Keithley 6517B Reference Manual

Section 8: Buffer (data store)
ELEMENTS
Optional data elements can be included for each reading stored in the buffer. After selecting
ELEMENTS, the status of each optional data element is displayed. A "y" indicates that the element is
in included, while an "n" indicates that the data element is not included. To change the status of a
data element, place the cursor on the data element status and press either manual RANGE key.
The optional data elements are described as follows:
Timestamp: When selected, the time stamp is displayed on the primary display for each stored
reading. The form that time stamp is displayed depends on the selected TYPE and FORMAT (see
TIMESTAMP).
Humidity and External Temperature: When selected, these readings are included in a NEXT display.
Note that the appropriate sensor has to be connected to the instrument, and it has to be enabled
through the DATA-STAMP item of GENERAL menu.
Channel: When selected, the scanned channel number is displayed on the primary display for each
stored reading. Note that if a scan was not performed, a channel number is not displayed even
though it is a selected data element.
V-source: When selected, the sourced voltage level is available as a multiple (NEXT) display.
DISPLAY
This menu item is used to enable or disable the display during the storage process.
YES: This option enables the display. When enabled, readings are displayed along with the message
that indicates that readings are being stored.
NO: With this option selected, the display and front panel are disabled ("FRONT PANEL DISABLED"
message displayed). This option optimizes speed and provides a more uniform interval between
readings. Pressing LOCAL during the storage process returns the display and front panel back to
normal.

Storing and recalling readings

The following tables detail the sequence of steps for the various modes of buffer control. The tables
assume the buffer is configured as explained previously. Note that during data storage, the reading
number on the bottom line of the display is one ahead of the reading on the top line.
There are "multiple displays" available when recalling buffered readings. These are explained below.
