11. Connect the 8588A for vdc measurement with the low thermal cable to the 732C 1 V (normal
polarity).
12. Record the 8588A measurement in the Vdmm_732C column for applicable steps.
13. Inverse the cable at the 732C 1 V (negative polarity).
14. Record the 8588A measurement in the Vdmm_732C column for applicable steps.
15. Connect the 8588A for vdc measurement with the low thermal cable to the 732C 10 V (normal
polarity).
16. Record the 8588A measurement in the Vdmm_732C column for applicable steps.
17. Inverse the cable at the 732C 10 V (negative polarity).
18. Record the 8588A measurement in the Vdmm_732C column for applicable steps.
19. Connect the test equipment as shown in Figure 3.
20. Connect a strap between the Guard and Ground terminals of the DUT.
21. Output from the DUT/Measure with the meter and record the 8588A measured values when
connected to the Product in the Vdmm_prod column. Refer to the product manual for how to set
and use range lock on the bottom range outputs.

22. For steps other than ±100 mV, ±1 V, and ±10 V the output of the Product is the same as the 8588A
measurement recorded directly when connected to the product output DMM Reading on Product
column. Copy the value to the Calculated Product Output column.
23. For the rest of the steps, calculate the Product output with this formula:
Calculated Product Output =
