PicoScope 4225 and 4425 Automotive Scopes
WARNING
To prevent injury or death, the oscilloscope must not be directly connected
to the mains (line power). To measure mains voltages, use a differential
isolating probe specifically rated for mains use, such as the TA041 listed
on Pico Technology's website.
CAUTION
Exceeding the overload protection range on any connector can cause
permanent damage to the oscilloscope and other connected equipment.
Grounding
WARNING
The scope's ground connection through the USB cable is for measurement
purposes only. The oscilloscope does not have a protective safety ground.
