Quick Start Guide PicoScope USB Oscilloscope

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 specied 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 specied 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 dierential

isolating probe specically 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

signicant 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.
