Using this guide
You will sometimes see a symbol like this : This is the cross-reference symbol, and it
indicates the number of a page on which you can find more information about a topic.
2.2
Safety symbols
The following symbols appear on the front panel of the PicoScope 6000 Series
oscilloscope.
Symbol 1: Warning triangle
This symbol indicates that a safety hazard exists on the indicated
connections if correct precautions are not taken. Read all safety
documentation associated with the product before using it.
Symbol 2: Equipotential
This symbol indicates that the outer shells of the indicated BNC
connectors are all at the same potential (shorted together). You must
therefore take necessary precautions to avoid applying a potential
across the return connections of the indicated BNC terminals. Such a
potential could cause a large current to flow, resulting in damage to
the product or connected equipment, or both.
2.3
Safety warnings
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.
DO NOT exceed the overload protection range. The product is designed to
measure signals within the range ±20 V. The inputs can withstand ±100 V to ground
(when set to 1 MΩ impedance) or 5.5 V RMS (when set to 50 Ω impedance). Contact
with voltages outside the overload protection range may cause permanent damage to
the unit.
DO NOT connect to mains voltages. The product is not designed for use with
mains (line) voltages. To measure mains voltages, use a differential isolating probe
specifically rated for mains use.
DO NOT rely on the scope's ground as a safety ground. The product connects
directly to the ground of a computer through the USB cable provided. This ground is
for signaling and shielding, and is not a safety ground.
DO NOT connect the ground input to any potential 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.
Connecting the ground input to a voltage source may cause damage to the scope and
the computer, and injury to yourself and others.
