A.3 Test Setup and Equipment

Figure 6-1 shows the benchtop test setup.

WARNING: Exercise extreme caution when working with high voltages! Injury or death could result from improper handling or usage of high-voltage circuits.

The HV circuits are enclosed in an HV interlock box that has safety switches which trip to turn off the HV power when the lid to the box is opened.
