1. Introduction
This addendum to the Model 7065 Instruction Manual is being provided in order to supply you with the latest
information in the least possible time. Please read over this information before using the Model 7065 Hall Effect Card
and associated equipment.
Although this addendum is intended primarily for purchasers of the Model 80A Hall Effect System, those who use
the Model 7065 along with their own equipment may also find this information helpful.
2. Equipment Changes
References to the Model 705 Scanner throughout the Model 7065 Instruction Manual should be changed to the
Model 7001 Switch System.
References to the Model 6167 Guarded Input Adapter throughout the Model 7065 Instruction Manual should be
changed to the Model 6172 2-Slot Male to 3-Lug Female Triax Adapter.
References to the Model 7024-10 Triaxial Cable (10 ft) throughout the 7065 Instruction Manual should be changed
to Model 7078-TRX-10 3-Slot Triax Cable (10 ft).
The Model 80A Hall Effect System has been discontinued, but drop-in replacements for all of its constituent parts
may still be purchased.
Each of the replacement models features an emulation mode to accept the control commands for the product it
replaces, so all of the program code in this manual can be used directly with no modifications.
The main impact of this equipment change is on the example programs listed at the end of paragraph 3.8 in the
Model 7065 Instruction Manual. These programs will not work with the Model 7001 Switch System and thus cannot
be used with the Model 80A. Modified versions of these programs are included with this addendum.
The various test procedures discussed in Section 3 should also be changed for operation with the new switch
system. The Model 7001 need not be placed in the matrix mode, but it must be configured for card type, as
discussed in paragraph 5 of this addendum. In addition, you can simultaneously open or close all crosspoints for a
given step in a test sequence with the OPEN and CLOSE keys. In order to do so, you must first set up a channel
list, as discussed in paragraph 6.

• Model 7065 Hall Effect Card
