1. Connect the DMM to the Product as shown in Figure 7 using the 5730A-7003
cables.
2. Set the 8508A to Resistance, True Ohms, 2 Ω range, 6 digits, normal current,
internal guard, 4 wire, and "Slow".
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
Measured Value column.
5. Set the Product to 1 Ω.
6. Wait for the reading to settle and then record the reading in the Table 5 DMM
Measured Value column.
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
Measured Value column.
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
into the Table 5, Measured Minus Displayed Resistance column.
12. Verify the difference is within the test limits given.
