1.3 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 the 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 2000 Series PC Oscilloscopes are designed to measure voltages in the range
-20 V to +20 V. Any voltages in excess of ±100 V 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 2000 Series PC Oscilloscopes connect directly 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 only by Pico Technology.
1.4 FCC notice
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
