The following descriptions explain how to use many of the accessories that
came with your probe. Figure 3-53 shows both standard and optional probe
accessories and how they attach to your probe.
These accessories either reduce ground lead inductance or make it physically
easier to probe different kinds of circuits.
Standard probe accessories include the following items.
Retractable Hook Tip
The retractable hook tip attaches to your signal test point for hands-free
operation of the probe. The hook tip attaches to components having leads,
such as resistors, capacitors, and discrete semiconductors. You can also grip
stripped wire, jumpers, busses, and test pins with the retractable hook.
For maximum flexibility with the hook tip, use one of the six-inch ground
leads. For precise measurements at high frequency, however, long ground
leads may have too much inductance. In these cases you can use one of the
low-inductance probe tip configurations instead.
To remove the hook tip, simply pull it off the probe. Reinstall it by pushing it
firmly onto the ribbed ferrule of the probe tip (see Figure 3-53).
