Moving to another USB port
The procedure for moving your PicoScope oscilloscope to another USB port depends on
your operating system.
Windows XP
When you first installed the PicoScope 3000 Series oscilloscope by plugging it into a
USB port, Windows associated the Pico driver with that port. If you later move the
oscilloscope to a different USB port, Windows will display the "New Hardware Found
Wizard" again. When this occurs, just click "Next" in the wizard to repeat the
installation. If Windows gives a warning about Windows Logo Testing, click "Continue
Anyway". As all the software you need is already installed on your computer, there is
no need to insert the Pico Software CD again.
Windows Vista, Windows 7 and Windows 8
The process is automatic. When you move the device from one port to another,
Windows displays an "Installing device driver software" message and then a
"PicoScope 3000 Series PC Oscilloscope" message. The oscilloscope is then ready for
use.

Compensating probes
We recommend that you compensate each oscilloscope probe before using it with your
PicoScope. Compensation instructions specific to the probe are included in the leaflet
supplied with the probe.
Connecting a probe for compensation (2-channel oscilloscopes and MSOs)
1. Plug the probe's BNC connector into the appropriate input channel on the scope.
2. Fit a BNC adapter (supplied with the probe) onto the probe tip.
3. Plug the probe tip with BNC adapter into the scope's
.
4. Run the PicoScope software.
5. Click the Signal Generator button and set the output to a 1 kHz 1.8 volt square
wave. Set the input coupling to AC and then click Auto Setup, which should ensure
that the correct range and timebase are selected.
6. Follow the compensation (or 'trimming') instructions in the probe leaflet.
Note: if the probe is moved to a different scope channel, the compensation procedure
must be repeated.
Connecting a probe for compensation (4-channel oscilloscopes)
1. Plug the probe's BNC connector into the appropriate input channel on the scope.
2. Fit the spring hook (supplied with the probe) on the probe tip.
3. Attach the spring hook to the
located on the front
panel.
4. Attach the ground lead (supplied) to the probe and connect the crocodile clip to the
ground shell of one of the scope's BNC inputs.
5. Run the PicoScope software. Set the input coupling to AC and then click Auto
Setup, which should ensure that the correct range and timebase are selected.
6. Follow the compensation (or 'trimming') instructions in the probe leaflet.
Note: if the probe is moved to a different scope channel, the compensation procedure
must be repeated.
