Grounding the Probe

2
Connect the probe to the instrument and connect the ground lead to ground
before making any measurement. Ensure that no part of the ground lead contacts
voltage in the circuit under test. Except for the probe tip and BNC center
conductor, all accessible metal (including the ground clip) is connected to the
BNC shell.
WARNING. To avoid electric shock when using the probe, keep your fingers
behind the finger guard on the probe body. See Figure 1 below.
