Pollution Degree
Description
A measure of the contaminants that could occur in the environment around
and within a product. Typically the internal environment inside a product is
considered to be the same as the external. Products should be used only in the
environment for which they are rated.
Pollution Degree 1. No pollution or only dry, nonconductive pollution occurs.
Products in this category are generally encapsulated, hermetically sealed, or
located in clean rooms.
Pollution Degree 2. Normally only dry, nonconductive pollution occurs.
Occasionally a temporary conductivity that is caused by condensation must
be expected. This location is a typical office/home environment. Temporary
condensation occurs only when the product is out of service.
Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution
that becomes conductive due to condensation. These are sheltered locations
where neither temperature nor humidity is controlled. The area is protected
from direct sunshine, rain, or direct wind.

Compliance Information
Pollution Degree 4. Pollution that generates persistent conductivity through
conductive dust, rain, or snow. Typical outdoor locations.
Pollution Degree Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.

Product End-of-Life
Handling
Observe the following guidelines when recycling an instrument or component:
Equipment Recycling. Production of this equipment required the extraction and
use of natural resources. The equipment may contain substances that could be
harmful to the environment or human health if improperly handled at the product’s
end of life. In order to avoid release of such substances into the environment and
to reduce the use of natural resources, we encourage you to recycle this product
in an appropriate system that will ensure that most of the materials are reused or
recycled appropriately.
This symbol indicates that this product complies with the applicable European
Union requirements according to Directives 2002/96/EC and 2006/66/EC
on waste electrical and electronic equipment (WEEE) and batteries. For
information about recycling options, check the Support/Service section of the

Compliance Information
xP6022 Instruction Manual

Operator Information
This manual describes the P6022 current probe with passive termination, and
provides information about making measurements with the probe.
Description
The P6022 current probe converts an alternating current waveform to a voltage
that can be displayed and measured on an oscilloscope display. It provides
accurate current measurements over a wide range of frequencies, and allows you
to measure current without breaking the circuit.
The P6022 probe is compatible with general-purpose ground-referenced
oscilloscopes having a 1 MΩinput impedance. The P6022 probe comes with a
passive termination that matches oscilloscope and probe impedance, optimizes the
probe performance, and provides two sensitivity settings.
The P6022 probe comes with a 5-foot cable, termination, and 6” ground lead.
Figure 1: P6022 probe, termination, and ground lead
P6022 Instruction Manual 1

Operator Information
Installation
This section describes both attaching the probe to an oscilloscope and using the
standard accessories with the probe.
To ensure the best performance from your probe/oscilloscope measurement
system, check that the probe and oscilloscope are appropriately matched. The
oscilloscope inputs should use BNC connectors, and have an impedance of 1 MΩ.
Figure 2: Connecting the probe and termination to the oscilloscope
2P6022 Instruction Manual

Operator Information
Attaching the Probe
and Termination to an
Oscilloscope
1. Connect the termination box female BNC end to the P6022 probe output cable.
2. Connect the termination box male BNC end to a ground-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 float the oscilloscope by removing or isolating the ground pin from the AC
power cord.
Do not use this probe with 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
ringing 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.
Never disconnect the probe from the termination when the probe is connected to
a live conductor.

Operator Information
Using the Standard
Accessories
Your P6022 probe is shipped with the following accessories:
This instruction manual — Read these instructions to familiarize yourself
with the features, specifications, and operation of the P6022 current probe.
6-inch ground lead —Usethe6-inchgroundleadtogroundtheshield
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 as shown.
