When conducting a power line superimposition test with a lightning surge tester, the phase voltage output from the CDN becomes unstable when pressing the start button.

When conducting a power line superimposition test with a lightning surge tester, the phase voltage output from the CDN becomes unstable when pressing the start button.

In the LSS series, the surge generation section also acts as a load.
When the surge generation section (load) is connected to the application phase, depending on the AC power supply used, voltage drop in the application phase or
voltage rise in the non-application phase may occur.
