reason.To make probe identification easy, clip matching colored rings onto
the probe cable and tip as shown.
H
Three-inch ground lead—Use the Three-inch ground lead to establish a
ground reference for your measurements. Whenever freedom from aberra-
tions and amplitude accuracy are more important than probe reach and
flexibility, use the shortest ground lead possible.
To attach the ground lead to the probe, insert the spring clip into the
receptacle as shown. If the alligator clip is not attached, screw it onto the
threaded end of the lead.
H
Five-inch ground lead—Use the long ground lead when a long reach is
important and high-frequency information is not. Because of the high
inductance associated with long ground leads, you should not use them for
precise measurements above approximately 30 MHz (or for pulses with rise
times less than about 11 ns). Long ground leads are ideal for quick trouble-
shooting when you are looking for the presence or absence of a signal and
are not concerned with the precision of the measurement.
The five-inch ground lead attaches in the same manner as the three-inch lead.
H
Alligator clip—Use the alligator clip with one of the ground leads. Screw
the alligator clip onto the threaded end of a ground lead.
