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 Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated
for indoor use only.
INSTALLATION (OVERVOLTAGE)
CATEGORY DESCRIPTIONS
Terminals on this product may have different installation (overvoltage) category
designations. The installation categories are:
Measurement Category I. For measurements performed on circuits not directly
connected to MAINS.
Measurement Category II. For measurements performed on circuits directly
connected to the low-voltage installation.
Measurement Category III. For measurements performed in the building
installation.
Overvoltage Category. Overvoltage Category II (as defined in IEC 61010-1)

DESCRIPTION
The CP6000 family of AC/DC current probes enables oscilloscope instruments to
display AC, DC, and AC+DC current measurements up to 100 amps peak
(CP6220) and frequencies up to 1.5 MHz (CP6990). Using supplied BNC to
Banana plug adapter (CT3956) the current probes will work with most modern
Digital Multimeter (DMM).

CURRENT FLOW SYMBOL
Arrow on current jaws shows the probe’s polarity convention for measuring
current flowing from positive to negative.
DC ZERO ADJUST
Rotate to adjust the probe output to zero when there is no current present. It may
also be used to offset a DC signal component. Zeroing is not needed for AC
measurements unless your instrument cannot isolate a DC component, if present.

OFF/RANGE SWITCH
Slide the switch from OFF to either the low or high measurement range. When
either range is selected, the probe is turned on, and the green battery indicator
lights. If the indicator does not light, see Battery and AC Power Adapter and
Battery Installation.
ON INDICATOR
The ON indicator lights green when the probe is turned on. For more information,
see Battery and AC Power Adapter and Battery Installation.
OVERLOAD INDICATOR
The overload indicator lights red if the measured signal is greater than the
selected range capability. Switch the probe to higher measurement range, if
possible, or remove the probe from the circuit.
BASIC OPERATION
Before using the probe a battery or specified power adaptor must be installed.
See Battery and AC Power Adapter and Battery Installation.
WARNING!
Do not clamp the probe onto circuits with voltages greater than 600 VAC (600V
CAT II, 300V CAT III). Personal injury or damage to the probe may result.
Always connect the current probe to an instrument before clamping onto the
circuit under test.
1. Connect the BNC cable (CT3955-100) to the current probe’s BNC female
output connector then connect the BNC cable to the oscilloscope’s BNC input.
Start by setting the oscilloscope’s voltage input channel to DC and the voltage
sensitivity to 0.1 V/div.
2. Move the OFF/Range switch to the low V/A or high V/A position. The green
ON Indictor LED will light. If the green ON Indictor LED does not light, replace
the battery or use included power adaptor.
3. Use the ZERO Adjust to zero or offset the probe output of residual magnetic
DC charges.
4. Connect the probe to the circuit by opening the jaws with the Jaws Opening
Lever and clamping around the conductor. See Figure 2.

CP6000MAN v01

Figure 2: Connecting the current probe
5. Adjust the oscilloscope’s channel amplitude and time base settings as
necessary to get a clear and stable signal. Set the oscilloscope input to DC volts
to see both the AC and DC currents; set the channel to AC to see the AC current
only. The current drawn by selected devices can vary. While the RMS current
can only be used in low frequency current, the transient peaks can be quite high.
Figure 3 shows the difference between a line current drawn by a resistive load
and a motor controller.
Figure 3: Typical current waveforms
When connecting the current probe to a Digital Multimeter (DMM), use the
included BNC-to-banana adapter (CT3956). Connect the black banana plug on
the adapter to the DMM’s COM or ground jack and the red banana plug to the
VΩjack.
To measure only AC current, set the meter to measure AC volts. To measure
DC current, set the meter to measure DC volts.

NOTE: the current convention arrow on the probe to get the proper polarity
reading.
NOTE: clamping around both the “hot” and “neutral” wires may give a zero
reading.
To increase the measurement sensitivity of the current probes, loop additional
turns of the wire under test through the jaws. See Figure 4. The sensitivity of the
current probe is multiplied times the number of loops in the jaws. For example:
200 mV/A X 4 turns = 800 mV/A.
Figure 4: Increasing the sensitivity
Remember to unclamp the probe from the conductor before disconnecting it from
your meter or instrument.

MAINTENANCE
Use the information in this section to properly maintain the operation of your
AC/DC Current Probe.
BATTERY AND AC POWER ADAPTER
A CP6000 Series current probe uses a single 9 V battery. As the probe is a high
power product, please use the specified alkaline battery.
As the battery installed is drained, a significant gain error may occur. The green
ON Indicator LED will continue to light until a low battery voltage of 6.5 V is
reached. If probe gain errors are detected, replace the battery.
The included AC Power Adapter can be used to avoid gain error due to a low
battery. Use the AC Power Adapter when there is AC power available.
The CP6000 Series current probes have in their design a priority external power
circuit, therefore it is safe to use the AC Power Adapter while the battery is
installed. However, when using the AC Power Adapter for an extended period,
removal of the battery is recommended.
BATTERY INSTALLATION
(1) Remove the probe from the circuit.
(2) Open the battery compartment by loosening and removing the three screws
on the back of the probe. Lift off the back cover.
(3) Observing polarity, attach the new alkaline battery to the connector buttons
and place the battery into the compartment, as illustrated in Figure 5.
(4) Replace the back cover and lightly tighten the three cover screws.

CLEANING
• Clean only the exterior of the probe, cables and accessories. Use a soft cotton
cloth moistened with a mild detergent and water solution. To clean the core,
open the jaw and clean the exposed core surfaces with a cotton swap dampened
with isopropyl alcohol. Lubricate the jaws mating surfaces with light oil. Do not
allow any portion of the probe to be submerged at any time.
• Dry the probe and accessory thoroughly before attempting to make any current
measurements.
• Do not subject the probe to solvents or solvent fumes as these can cause
deterioration of the probe body, cables and accessories.
