Verifying Two-Wire Resistance; Figure 10-7: Verifying Four-Wire Resistance - Keithley 3700 series Reference Manual

Section 10: Verification
7. Source the nominal full-scale resistance values for the 100-10M ranges summarized in
the Resistance verification table. Recalculate the limits based on the actual value of the
resistor and verify the reading is within the calculated limits.

Verifying two-wire resistance

Check the normal resistance function by connecting accurate resistance values to the Series
3700 analog backplane connector and verify that the displayed readings fall within specified
limits.
