Frequency Measurement
To verify the frequency measurement function:
1. Connect the UUT as shown in Figure 4 .
2. Set the UUT to the frequency measurement function.
3. Select the <20 Hz range for the first step. Use the ≥20 Hz range thereafter.
4. Set the 5522A to the first test point in Table 7.
5. See if the frequency value shown on the UUT is in the range shown in the
applicable column.
6. Continue through the test points.
7. When you complete the test, set the 5522A to STANDBY.

DC Volts Source
To verify the dc volts source function:
1. Connect the UUT to the 8508A as shown in Figure 5.
2. Set the 8508A to measure dc volts.
3. Set the UUT to the dc volts source function at -10 mV. Let the UUT warm up for
a minimum of 5 minutes before you read the first indication.
4. See if the value shown on the 8508A is in the range shown in the applicable
column in Table 8.
5. Continue through the test points. See if the value shown on the UUT is in the
range shown in the applicable column.
6. When you complete the test, push on the UUT two times to turn the source
function off. This conserves battery life.
