1-14 Performance Verification
6. Source the nominal full-scale resistance values for the 100Ω-10MΩ ranges summarized
in Table 1-6, and verify that the readings are within calculated limits.
7. Connect the Model 2700 INPUT and SENSE jacks to the calibrator as shown in
Figure 1-6.
8. Disable external sense on the calibrator.
9. Set the Model 2700 for the 100MΩ range.
10. Source a nominal 100MΩ resistance value, and verify that the reading is within calcu-
lated limits for the 100MΩ range.
