Fig.2 Charged Section and High Voltage Generating Point (Rear View)
Charged Section
The places where the commercial AC power is used without
passing through the power supply transformer.
If the places are touched, there is a risk of electric shock. In
addition, the measuring equipment can be damaged if it is
connected to the GND of the charged section and the GND of the
non-charged section while connecting the set directly to the
commercial AC power supply. Therefore, be sure to connect the
set via an insulated transformer and supply the current.

High Voltage Generating Point
The places where voltage is 100V or more except for the charged
places described above. If the places are touched, there is a risk of
