1. Connect the DMM to the Product as shown in Figure 7 using the 5730A-7003
2. Set the 8508A to Resistance, True Ohms, 2 Ω range, 6 digits, normal current,
3. Set the Product to output 0 Ω, 4-wire sense on, and then push .
4. Wait for the reading to settle and record the reading in the Table 5 DMM
5. Set the Product to 1 Ω.
6. Wait for the reading to settle and then record the reading in the Table 5 DMM
7. Set the Product to 1.9 Ω.
8. Wait for the reading to settle and then record the reading in the Table 5 DMM
9. Push  to put the Product in standby.
10. Enter the value shown on the Product display for 1 Ω and 1.9 Ω into Table 5.
11. Enter the difference in the measured resistance and the resistance shown
12. Verify the difference is within the test limits given.
