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 specied 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.

Input range Overvoltage protection

Full-scale measurement ±50 V DC and ±42.4V pk max AC ±100V DC + AC peak

Common-mode ±50 V DC and ±42.4V pk max AC ±100V DC + AC peak

WARNING

To prevent electric shock, do not attempt to measure voltages outside the specied

full‑scale measurement or common‑mode ranges above.

WARNING

Signals exceeding the voltage limits in the table below are dened 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

±60 V DC 30 V AC RMS ±42.4 V pk max.

PicoScope USB Oscilloscope Quick Start Guide

WARNING

To prevent injury or death, the oscilloscope must not be directly connected to

hazardous live signals as dened by EN 61010. To measure such voltages, use

a differential probe specically rated for this use, such as the PicoConnect442

1000V CATIII differential probe.

CAUTION

Exceeding the overload protection range of the oscilloscope and its recommended

accessories can cause permanent damage to the oscilloscope and other connected

equipment.

If the signal voltage exceeds the measurement input range, the PicoScope software displays

the red overrange indicator in the top left corner of the display, with the message “Channel

overrange”. A smaller version appears next to the vertical axis of the affected channel. The

waveform will be clipped: no data outside the measurement input range will be shown. In the

software, increase the input range of the affected channel until the indicator disappears.

If the common‑mode voltage of the differential input exceeds the scope’s common‑mode

input range, the yellow common‑mode overrange indicator appears, with the message

“Common‑mode overrange”. Again, a smaller version appears next to the vertical axis of the

affected channel. Exceeding the common‑mode input range of the scope causes inaccurate

measurements and can lead to severe signal distortion.

1.2.3 Grounding

WARNING

The oscilloscope’s ground connections through the USB cable and through the

ground terminal are for measurement purposes only. The oscilloscope does not

have a protective safety ground.

WARNING

Never connect the ground terminal (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 USB cable supplied with the oscilloscope.
