1. Connect the UUT to the 8508A as shown in Figure 8. Use a four-wire connection
transitioning to two wires at the UUT.
2. Set the UUT to the resistance source function at 0.1 Ω.
3. On the 8508A, select four-wire ohms measurement and up-range to the 200 Ω
range. Use the 200 Ω range for the first five tests points, and autorange
thereafter. The low range of the 8508A supplies too much current into the UUT.
4. See if the value shown on the 8508A is in the range shown in Table 11.
5. Continue through the test points. See if the value shown on the UUT is in the
range shown in the applicable column of Table 11.
6. When you complete the test, push  on the UUT two times to turn off the
source function. This conserves battery life.
