Step 5500A Output Comments
32 320 MΩ [1] 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, R
UUT
, into the HP 3458A. In the equation, R
3458
is the
reading of the HP 3458A, R
742
is the printed value of the 742A-10M, and R
UUT
is the actual 5500A
output.
