External Connections - PICO PicoScope Kurzanleitung

Quick Start Guide
PicoScope detects a signal voltage exceeding the selected full-
scale measurement range and indicates it on the measurement
display. A red warning icon will appear in the upper left corner and
next to the relevant channel's vertical axis.
Under these conditions, displayed waveforms and measurements
may be incorrect and the condition may be hazardous. Select
a larger voltage range to achieve a within-range measurement
and if the condition persists, to prevent injury or death, disable or
otherwise safely disconnect from the source of overvoltage.
To avoid causing permanent damage to the oscilloscope and other connected equipment, do
not exceed the voltage rating of any cable, connector or accessory.
2.3 Grounding
The oscilloscope's ground connection through the USB cable is for measurement purposes
only. The oscilloscope does not have a protective safety ground.
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.
To avoid causing permanent damage to the oscilloscope, the attached computer and other
equipment, never apply a voltage to the ground input.
To prevent measurement errors caused by poor grounding, always use the high-quality USB
cable supplied with the oscilloscope.

External connections

To prevent injury or death, use only the power cord and adaptor, if any, supplied with the
product. These are approved for the voltage and plug configuration in your country.
Note: Not all oscilloscopes require an external power supply.

DC power supply may be required for 4-channel models if USB port supplies insufficient power.
[1]
DC power supply is required for full functionality of 4-channel models. Refer to the Data Sheet
[2]
for details.
Take care to avoid mechanical stress or tight bend radii for all connected leads, including
all coaxial leads and connectors. Mishandling will cause deformation and will degrade
performance and measurement accuracy.
