19. Set the Product to output 121 k Ω . Set the meter to the Resistance function. Measure with the meter
and record the 8588A measured value in the DMM Measurement on Product column in Table 10.
20. Set the product to Standby.
21. Connect the 8588A to Fluke 742A-1M for 2-Wire measurement.
22. Measure with the meter and record the 8588A measured value in the DMM Measurement on
Transfer Resistor column in Table 10.
23. Disconnect the 8588A from the resistor standard and connect the cables to the product for 2-W
measurement.
24. Set the Product to output 1 M Ω . Measure with the meter and record the 8588A measured value in
the DMM Measurement on Product column in Table
25. Set the Product to Standby.
26. Complete steps 18 to 22 in Table
measures a resistor following by the Product measurement. For all steps, connect the cable
between meter and resistor guard terminals.
27. The subsequent section (steps 23 to 26 in Table 10) uses characterization and linearization of the
8588A 1 G Ω range at 100 M Ω and 1 G Ω .
28. Input the values for both standards in the Transfer Value column in Table 9.
29. Set the 8588A as follows: Resistance 2Wire, LoI OFF, Range 1 G, NPLC 50, Guard OFF (external
guard light ring off).
30. Connect the 8588A to 100 M Ω standard for 2-Wire measurement. Use appropriate adapters at the
resistor standard to accommodate the connection.
31. Measure with the meter and record the 8588A measured value in the DMM Measurement on
Transfer Resistor column in Table 9, step 1.
32. Connect the 8588A to 1 G Ω standard for 2-Wire measurement. Use appropriate adapters at the
resistor standard to accommodate the connection.
33. Measure with the meter and record the 8588A measured value in the DMM Measurement on
Transfer Resistor column in Table
