Entry - HP 8340A Operating Manual

Model 8340A
INSERT IN FRONT OF THE OPERATING INFORMATION MANUAL IN SECTION Ill, OPERATION
The Operating Information manual in section III is a bound section of the manual. This allows
the operator to remove the document and refer to it more easily. However, the binding makes it
impossible to provide replacement pages for this section. This supplement should be kept with
the Operating Information booklet for reference.
The following information documents corrections and revisions to the Operating Information
manual. Information accompanied by the term "ALL SERIALS" applies to any HP 8340A,
regardless of serial number. Information accompanied by a serial number prefix (e.g. 2447A,
etc.) only applies to instruments of that serial number prefix or higher.

the Controller Section.
External Controller Programming:
An HP Series 200 controller may be programmed to interrogate the HP 8340A and print
out the results of the 32
characters to the external controller. These characters may be either 1 or 0 indicating a
passed or failed test respectively. The external controller will print the name of each test
and show whether it passed or failed. Test results will be printed out on the device specified
by the operator. In Basic:
