Use 8508A to Adjust the 5522A Output

To use the 8508A to calibrate the 5522A output:

1. Connect the voltage output terminals of the 5522A with the voltage input

connectors of the 8508A via the pure copper cables.

2. Set the resolution of DCV measurement mode to 7 1/2-digits or above.

3. Adjust the output of the 5522A until the reading of the 8508A is -10 mV

±0.2 μV, and record the voltage setting of the 5522A (=Voltage

-10mV

Setting).

4. Adjust the output of the 5522A until the reading of the 8508A is 75 mV

±0.2 μV, and record the voltage setting of the 5522A (=Voltage

75mV

Setting).

Note

The two voltage setting records are used to calibrate the UUT.

Adjust mV Source

To calibrate the 714B mV Source function:

1. Connect the 714B TC mini plug and the 8508A with pure copper cables, as

shown in Figure 15.
