Keithley 2015 Service Manual

Performance Verification 1-15
6. Source the nominal full-scale resistance values for the 100 Ω -10M Ω ranges summarized
in Table 1-6, and verify that the readings are within calculated limits.
7. Connect the Model 2015 INPUT and SENSE jacks to the calibrator as shown in
Figure 1-6.
8. Disable external sense on the calibrator.
9. Set the Model 2015 for the 100M
Ω range.
10. Source a nominal 100M Ω resistance value, and verify that the reading is within cal-
culated limits for the 100M Ω range.
