Connect the logic probe:
1. Turn off the power supply of the device under test.
2. Connect the output terminal of the logic probe to the digital channel input
terminal on the front panel of the oscilloscope in the correct direction, as shown
in Figure 1-6.
3. Connect the signal lead of each probe at the input terminal of the logical probe to
the test point of the signal under test.
4. Connect the ground lead of each probe at the input terminal of the logical probe
to the ground test point near the signal under test, as shown in Figure 1-7 (a).
Figure 1-7 (b) shows the incorrect connection of the ground lead, which fails to
connect the ground lead to the ground test point near the measured signal.
