PicoScope 2104 & 2105 PC Oscilloscope User Guide

1.3Safety warning

We strongly recommend that you read the general safety information below before using your PicoScope PC 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

The PicoScope 2104 and 2105 PC oscilloscopes are designed to measure voltages in the range -20 V to +20 V and are protected against continuous or transient overvoltages of up to ±50 V. Any voltages in excess of ±50 V may cause permanent damage to the oscilloscope or to your computer.

Measurement category

PicoScope 2000 Series PC Oscilloscopes are rated for use in measurement category I (EN61010 CAT I), which covers measurements on circuits not connected to the mains. You must not use your PicoScope PC Oscilloscope to make measurements on any circuit directly connected to the mains, unless you use a purpose-built isolating probe rated for the appropriate voltage and measurement category.

Safety grounding

The PicoScope PC Oscilloscopes connect directly to the ground of a computer through the interconnecting cable provided.

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

PicoScope PC Oscilloscopes contain no user-serviceable parts. Repair or calibration of the unit requires specialised test equipment and must be performed only by Pico Technology. Spare probe tips are available from Pico Technology and its authorised distributors.
