Figure 6-4 shows the simplified test circuit for using the Ω2 function of the Model 2790
with the 7702 module to measure high ohm DUT (i.e., insulation resistance) up to 120MΩ.
The DUT is connected to channel 1 of the 7702. When channel 1 is closed using system
channel operation, the DUT connects to the DMM of the Model 2790.
