Oscilloscope Diagnostics Kit Quick Start Guide
Pico Technology
The first drop-down menu selects the range of signal that you are interested in
measuring. If any custom ranges are defined, these will also be displayed here.
The second drop-down menu selects either AC or DC coupling.
The third drop-down menu selects a vertical zoom factor of x1, x2 or x5, allowing smaller
details in the signal to be viewed.
Additional information on the rest of the drop-down menus in the top toolbar can be
found in the help menu installed with the software.
On the bottom toolbar, the 'STOP' / 'GO' button starts and stops the capturing of
waveforms (the spacebar has the same effect). When you stop the oscilloscope, it will
hold the last waveform on the display.
The bottom toolbar also contains the controls for setting up the triggering conditions for
the oscilloscope. Triggering is used to select the moment when PicoScope starts to collect
data to display. This is usually at some fixed time before or after a trigger event. There is
only one set of trigger settings, which applies to all views.
A trigger event occurs when a specified channel crosses a voltage threshold (while rising
or falling). PicoScope can start collecting data immediately after the trigger event or at a
fixed time interval before or after the trigger event.
After PicoScope has collected a block of data and displayed it, it can either start looking
for the next trigger event (repeat mode), or stop collecting (single mode), leaving the
data after the trigger on the display.

Making your first measurement
We suggest that you first use the Oscilloscope Diagnostics Kit to capture the current and
voltage waveforms from the alternator. You will find this option in the Automotive Menu
under Miscellaneous | Charging circuits | Current / Volts. The help page that
appears automatically will show you how to connect the different parts of the
Oscilloscope Diagnostics Kit and give you a basic understanding of the kit.
