4. Test procedures
1.
Connect the probe as instructed above.
2.
Run the PicoScope software. Set Channel A to DC coupling and the ±5 V range.
3.
Connect the black test lead and sprung hook to the Cal – output on the back of
the oscilloscope.
4.
Connect the red test lead and sprung hook to the Cal + output on the back of
the oscilloscope.
5.
Verify that the scope display shows a 1 kHz square wave with 4 V peak
amplitude.
