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 included as PDF files on the software disk
and 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.

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 the scope chassis or
ground. The overvoltage protection range is the maximum voltage that can be
applied without damaging the instrument.
