Load Current Test
To test the load current, set up the UUT with equipment as shown in Figure 2 and complete the
following procedure:
1. Set the DMM to the mA dc function.
2. Apply 600 V dc from the Source. The DMM reading should be < 5 mA.
3. Apply −600 V dc from the Source. The DMM reading should be < 5 mA.
