Maximum input ranges
Observe all terminal ratings and warnings marked on the product.
WARNING
To prevent electric shock, operate within the safe input range for your scope,
which can be found in the
User’s Guide
.
WARNING
To prevent electric shock, take all necessary safety precautions when
working on equipment where voltages above the specified input range may
be present. Although the front-panel BNC inputs of the oscilloscope are
designed to withstand accidental overloads, contact with voltages outside of
the specified measuring range presents a risk of electric shock.
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
the Pico website.
CAUTION
Operation outside of the safe input range is likely to 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.
WARNING
Never connect the ground input (chassis) to any electrical power source. To
prevent personal injury or death, use a voltmeter to check that there is no
significant AC or DC voltage between the oscilloscope ground and the point to
which you intend to connect it.
CAUTION
Applying a voltage to the ground input is likely to cause permanent damage
to the oscilloscope, the attached computer, and other equipment.
CAUTION
To prevent measurement errors caused by poor grounding, always use the
high-quality blue USB cable supplied with the oscilloscope.
