WARNING
When measuring power line signals, be extremely careful
and use a step down isolation transformer whose output is
compatible with the input measurement capabilities of this
product. The product’s front and rear panels are typically at
earth ground. Thus, never try to measure AC power line
signals without an isolation transformer.
