Attaching the Probe
and Termination to an
Oscilloscope
1. Connect the ter
mination box female BNC end to the P6022 probe output cable.
2. Connect the termination box male BNC end to a g round-referenced
oscilloscope
.
WARNING. To avoid electric shock and possible injury, do not apply any voltage
above earth ground potential to the probe common lead (do not float the common).
The exposed metal on the probe output cable and termination box is electrically
connected to the probe common lead and therefore is at the same potential.
This probe is intended for use with ground-referenced oscilloscopes only. Do
not fl oat the oscilloscope by removing or isolating the ground pin from the AC
power cord.
Do not use this probe w ith any equipment with floating inputs, including the
TPS2000 or THS700 series oscilloscope.
3. When you make high frequency measurements, snap the ground lead to the
probe transformer post and attach the alligator clip directly to RF ground to
improve EMI rejection at high frequencies (2 MHz and above). This reduces
ringi
ng and helps to bypass capacitively-coupled RF currents which can flow
into the probe cable.
WARNING. To avoid potential shock and damage to the probe, do not disconnect
the probe termination and leave the P6022 clamped around the conductor when
measuring high currents. Leaving the probe cable unterminated can cause a high
voltage to develop in the secondary winding which may pose a shock hazard
and
damage the current probe transformer. Never disconnect the probe from the
termination when the probe is connected to a live conductor.
Ne
ver disconnect the probe from the termination when the probe is connected to
a live conductor.
