Ohms Output

The ohms output performance test verifies the accuracy of the ohms output from the front
of the Product. Use the DMM to measure the ohms output. Apply the values shown in
Table 7. See Figure 6 for connections.
Make sure the sense wires from the 8508A are on the bottom of the
stackable leads.
Push to select the 400 Ω, then the 4000 Ω range.
The 8508A should be set to the 2 k
