noise.
Concerning the Oscilloscope or Voltage Measuring Instrument to
Which the Probe is Connected
Whenever it is likely that the ground protection is impaired, you must
make the instrument inoperative and secure it against any unintended
operation.
If you energize the instrument by an auto transformer (for voltage
reduction or mains isolation), the ground pin of the input connector
terminal must be connected to the earth terminal of the power source.
