Make a two-wire measurement
[1] Perform this test using the HP 3458A in the 10 MΩ range and the Fluke 742A-10M in
parallel with the 5500A output. Using exactly 10 MΩ, the nominal value displayed on the HP 3458A is
9.66667 MΩ. Figure 3-4 shows the connections and the equation you use to calculate actual
resistance. Enter the calculated actual resistance, RUUT, into the HP 3458A. In the equation, R3458 is the
reading of the HP 3458A, R742 is the printed value of the 742A-10M, and RUUT is the actual 5500A
output.
