9. Example Resistivity and Hall Voltage Programs
Four example programs are included with this addendum. These programs are modified versions of those included
in the Model 7065 manual, and they are intended to run only with a Model 80A Hall Effect System. Refer to Section
3 of the Model 7065 Instruction Manual for detailed test descriptions.
NOTE
The Models 2000, 6485, and 622x have emulation modes to accept the command
sets used for 196/199, 485, and 220 respectively. If it is desired to use the following
programs, see the product manuals for the 2000, 6485, and 622x for instructions on
using them in emulation mode.
The programs and test configurations include (for Programs 1 and 2, also reference Figure 3 for additional
information):
• Program 1, Hall Voltage coefficient
• Program 2, Resistivity of van der Pauw samples
• Program 3, Resistivity of bar samples
• Program 4, Resistivity of 6- and 8-contact samples
