Resistance Measurement

Proceed as follows to verify the Resistance Measurement function:
1. Connect the UUT to the 5500A as shown in Figure 4. Use a four-wire connection at
2. Set the UUT to the Resistance Measurement function.
3. Press [RANGE] on the UUT to lock on the 11Ω range.
4. Set the 5500A to the first test point in Table 6.
5. Observe that the reading on the UUT is within the range shown under the appropriate
6. Continue through the test points, being careful to lock the UUT on the specified
7. When you are finished, set the 5500A to [STANDBY].
