Resistance calibrator used for 2MΩ-200MΩ ranges. Model 5156 Calibration
Standard used for 2GΩ-200GΩ ranges. Characterized resistance standards
used for 2TΩ-200TΩ ranges. Standards must be characterized to uncertainty
at least four times better than equivalent Model 6517A specifications and
mounted in shielded test box. (See Figure 1-8.)
