Basic Operation
Grounding the Probe
The 6-inch ground lead grounds the shield around the probe transformer at the probe end of the cable. This allows you to move the
ground connection closer to the circuit you are measuring, thereby improving high frequency response.
When you take high frequency measurements,
connect the probe ground lead to the probe
ground connector and attach the alligator clip
directly to RF ground to improve EMI rejection.
In some cases, it may be helpful to move the
ground lead or reposition the probe away from
noise sources in the circuit under test.
1. Clip the ground lead to the ground post at
the bottom of the probe head.
2. Connect the alligator end of the clip to the
circuit ground.
3. Clamp the probe around the circuit
conductor.
