Safety warning

We strongly recommend that you read the general safety information below before using
your oscilloscope for the first time. Safety protection built in to equipment may cease to
function if the equipment is used incorrectly. This could cause damage to your computer,
or lead to injury to yourself and others.
Maximum input range
PicoScope 3000 Series PC Oscilloscopes are designed to measure voltages in the range
-20 V to +20 V and are protected to ±50 V (3204/5/6 variants) or ±100 V (3224/3424
variants). Contact with voltages outside the protection range may cause physical damage.
Mains voltages
Pico Technology products are not designed for use with mains voltages. To measure
mains, use a differential isolating probe specifically designed for a high source voltage.
Safety grounding
PicoScope 3000 Series PC Oscilloscopes connect direct to the ground of a computer
through the interconnecting cable provided. This method minimises interference.
As with most oscilloscopes, avoid connecting the ground input to any source other than
ground. If in doubt, use a meter to check that there is no significant AC or DC voltage
between the ground input of the oscilloscope and the point to which you intend to connect
it. Failure to check may cause damage to your computer, or lead to injury to yourself and
others.
You should assume that the product does not have a protective safety earth.
Repairs
The oscilloscope contains no serviceable parts. Repair or calibration of the oscilloscope
requires specialised test equipment and must be performed by Pico Technology.
