1.1 Introduction
Thank you for purchasing a PicoScope 4444 differential PC oscilloscope, a highly flexible
differential oscilloscope suitable for a wide range of voltage measurement applications.
This guide explains how to install the PicoScope software and connect and set up your
oscilloscope. For further information on the software, please refer to the PicoScope 6 User's
Guide. For technical data relating to the oscilloscope itself, see the PicoScope 4444 Data Sheet.
Both are available for download from www.picotech.com/downloads. You can also access the
PicoScope 6 User's Guide from the Help menu within the PicoScope software.

WARNING
To prevent injury or death, use the product only as instructed and use only the
accessories that have been supplied or recommended. Protection provided by the
product may be impaired if used in a manner not specified by the manufacturer.
1.2.2 Maximum input ranges
Observe all terminal ratings and warnings marked on the product.
The full‑scale measurement range is the maximum voltage that the PicoScope 4444 can
accurately measure. The common‑mode range is the maximum voltage that can be applied to
both differential inputs with respect to the scope chassis or ground. The overvoltage protection
range is the maximum voltage that can be applied without damaging the instrument.
Full-scale measurement ±50 V DC and ±42.4V pk max AC
Common-mode ±50 V DC and ±42.4V pk max AC
WARNING
To prevent electric shock, do not attempt to measure voltages outside the specified
full‑scale measurement or common‑mode ranges above.
WARNING
Signals exceeding the voltage limits in the table below are defined as "hazardous
live" by EN 61010. To prevent electric shock, take all necessary safety precautions
when working on equipment where hazardous live voltages may be present.
Signal voltage limits of EN 61010-1:2010-1:2021+A1:2019
