Basic Operation
Basic Operation
CAUTION. Do not force conductors larger than 5.0 mm (0.20 in) into the probe jaws. Damage to the probe may result. The mating
surfaces of the probe head transformer are precision-polished and should be handled with care. Measurements may be degraded
by dirt on the mating surfaces of the probe head transformer. Refer to the Maintenance section of this manual for information on
how to properly clean the probe head transformer surfaces.
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. The ground lead
clips onto the ground connector on the bottom of the probe.
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 at high frequencies (2 MHz and above). This will help bypass
capacitively-coupled RF currents which can
fl ow into the probe cable. 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.
