Low Resistance Source (LVR) Verification

To verify the Low Resistance Source function:
1. Connect the low resistance source output to a standard multimeter as shown
2. Push  on the Product.
3. Push the softkey labeled MODE until lvr shows above the right-most Product
4. Set the multimeter for true ohms and auto range.
5. Measure the Low Resistance calibration performance at each resistance
