Verify 4-Wire Ohms Measure
1. Push to set the 712B to Ohms Measure mode.
2. Push until 4W shows on the screen.
3. Make the connections between the 712B and the 5522A, as shown in
Figure 3.
4. Set the 5522A to output the Ohms value at the second column in Table 5.
5. Wait approximately 10 seconds for a stable output of the 5522A, and verify
that the 712B readings are within
the limits shown.
