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
the 5500A, transitioning to two wires at the UUT, and turn Two-Wire Compensation
on.
2. Set the UUT to the Resistance Measurement function.
3. Press [RANGE] on the UUT to lock on the 11
Ω
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
column.
6. Continue through the test points, being careful to lock the UUT on the specified
range.
7. When you are finished, set the 5500A to [STANDBY].
