AC Volts Measurement
To verify the ac volts measurement function:
1. Connect the UUT to the 5522A as shown in Figure 1.
2. Set the UUT to the ac volts measurement function.
3. Push the Range softkey on the UUT to lock on the 3.0 V range.
4. Set the 5522A to the first test point in Table 4.
5. Stop to let the output become stable.
6. See if the value shown on the UUT is in the range shown in the applicable
column.
7. Continue through the test points. Make sure to lock the UUT on the specified
range.
8. When you complete the test, set the 5522A to STANDBY.

DC Current Measurement
To verify the dc current measurement function:
1. Connect the UUT to the 5522A and the 8508A as shown in Figure 2.
2. Disconnect the jumpers on the three common jacks (lows) of the UUT if they are
present.
3. Set the UUT and the 8508A to the dc current measurement function and the
5522A to source dc current.
4. Push the Range softkey on the UUT to lock on the 30 mA range.
5. Set the 5522A to the first test point in Table 5, and edit its output so that the
correct value shows on the 8508A.
6. See if the value shown on the UUT is in the range shown in the applicable
column.
7. Continue through the test points. Make sure to lock the UUT on the specified
range.
8. When you complete the test, set the 5522A to STANDBY.

Resistance Measurement
To verify the resistance measurement function:
1. Connect the UUT to the 5522A as shown in Figure 3.
2. Use a four-wire connection at the 5522A, transitioning to two wires at the UUT,
and turn on Two-Wire Compensation.
3. Set the UUT to the resistance measurement function.
4. Push the Range softkey on the UUT to lock on the 10 Ω range.
5. Set the 5522A to the first test point in Table 6.
6. See if the value shown on the UUT is in the range shown in the applicable
column.
7. Continue through the test points. Make sure to lock the UUT on the specified
range.
8. When you complete the test, set the 5522A to STANDBY.
