Figure 13 – Oscilloscope probe
Connect the probe to the oscilloscope and connect the ground terminal to ground before you
take any measurements.
WARNING: SHOCK HAZARD
To avoid electric shock when using the probe, please make certain that the insulated wire of
the probe is in good condition and do not touch the metallic parts of the probe when it is
connected to a high voltage.
Do not connect the probe's ground lead (e.g., using the supplied alligator clip) to any point in
a circuit that is not at ground potential. If you're not sure whether a point you want to
connect to is at ground potential, first check it with a known-working high-impedance digital
voltmeter.
Probe Attenuation
Probes have attenuation factors that can affect the vertical display of the signal. Before making
measurements with the probe, verify the probe's attenuation matches the attenuation setting of
the oscilloscope channel it is connected to. Push the numbered button corresponding to the
channel the probe is connected to and ensure the attenuation factor shown on the Probe softkey
matches that of the probe. Failure to do this will result in significant measurement error.
