Signals exceeding the voltage limits in the table below are de昀椀ned as "hazardous live" by
EN 61010.
Signal voltage limits of EN 61010-1: 2010+A1:2019
±60 V DC
To prevent injury or death, do not directly connect the oscilloscope to hazardous live voltages.
To prevent electric shock, take all necessary safety precautions when working on equipment
where hazardous live voltages may be present.
The following accessories can safely connect to and allow measurement of hazardous live
voltages, up to either the instrument's full-scale measurement voltage multiplied by the applicable
attenuation ratio or the accessory's marked maximum operating voltage, whichever is the lower:
• P1053 10:1 passive high-impedance oscilloscope probes
• All Pico Technology-supplied high-voltage active probes
Accessories suited for connection to hazardous live voltages are clearly marked with their
maximum allowable voltage and, where applicable, their CAT rating.
To prevent electric shock, do not exceed the voltage rating marked on any accessory. If an
accessory is not marked with a voltage rating on either the connector, cable or body, or if a
protective 昀椀nger guard is removed, then do not exceed the EN 61010 "hazardous live" limits
above. When connecting one or multiple accessories and an instrument channel together, the
lowest voltage rating in the chain applies to that channel.
To prevent injury or death, do not directly connect the oscilloscope to the mains (line power).
To measure mains voltages, use only a differential isolating probe that is speci昀椀cally CAT
rated for mains or high energy use, such as the TA041 listed on the Pico website. Such
measurements must only be made by competent persons and appropriate safety training may
be required.
To prevent injury or death, do not use the product or an accessory if it appears to be damaged
in any way, and stop use immediately if you are concerned by any abnormal operations.

If PicoScope detects a signal voltage exceeding the selected full-scale
measurement range, it is indicated on the measurement display. A
red warning icon will appear in the upper left corner and next to the
relevant channel's vertical axis.
In 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 signi昀椀cant 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.
2.4 External connections
To prevent injury or death, use only the Pico approved power adaptor supplied with the
product. These are approved for the voltage and plug con昀椀guration in your country.
