The P6022 probe is compatible with general-purpose ground-referenced

To Use the Probe
WARNING. To reduce risk of electric shock, use only insulated conductors with
these probes on circuits with voltages above 30 Vrms, 42 Vpk, or 60 VDC. These
probes are not rated for bare wire voltages above 30 Vrms, 42 Vpk, or 60 VDC.
CAUTION. Toreduceriskoffire, do not connect or disconnect the current probe to
or from a live, uninsulated conductor. The core is not insulated. Always remove
power before you connect or disconnect the probe to or from bare conductors.
NOTE. An insulated conductor is any conductor that is surrounded by an
insulating material that is capable of isolating the voltage present on the
conductor. Lacquer coatings like those typically found on transformer windings

insulating capabilities of the lacquer coating.
CAUTION. To prevent damage to the probe, do not drop the probe, subject it
to physical shock or rapid temperature changes, and do not insert insulated
conductors larger than 2.6 mm into the probe jaw or damage may result. If the
slider will not close around the conductors, do not force the slide closed, either

Current Probe
iption
This section describes the circuits in the P6022 current probe and termination.
The P6022 current probe consists of a current transformer mounted in the nose of
the probe head case, an impedance-matching network, and an internal switch to
disconnect the transformer shield from ground.
The transformer contains a two-section, U-shaped ferrite core. One section is
stationary; the other is mechanically movable to permit closing the core around
the conductor being measured. The conductor under test forms a one-turn primary
winding f
core are the secondary windings. The circuitry between the transformer and the
coaxial cable corrects any differences in level between the pulses induced in the
windings of the secondary, and matches the balanced probe winding to the cable.
As indicated on the probe body, the turns ratio of the P6022 is 50:1. This refers to
the number of windings in the secondary of the probe transformer.
The probe transformer is shielded to eliminate interference from outside signals.
To eliminate the possibility of creating a short circuit from this shield to the
conductor being measured, the slide switch disconnects the ground from the
shield when you open the sliding portion of the probe to connect or remove it
from
or the transformer; the windings around the stationary portion of the
a conductor.
Termination
The P6022 termination consists of an impedance-matching network to terminate
the coaxial cable, and a voltage divider that is switched in by a sensitivity control
change the sensitivity by a factor of five. When the control is in the 1 mA/mV
to
position, a 10 mA current signal in the conductor under test induces a 10 mV
signal at the output of the termination. (This assumes that the termination is
connectedtoa1MΩ input oscilloscope.)
When the sensitivity control is in the 10 mA/mV position, a 10 mA current signal
is attenuated to induce a 1 mV signal at the output of the termination.

can degrade low-frequency response. Clean these surfaces if necessary.
Calibration procedures can also be used as performance checks by completing all

Adjustment Procedure
Preparation
If the probe does not pass the performance verification procedure or you want
to optimize the performance of the probe, perform the following adjustment
procedure:
1. Insert a small screwdriver between the cover and the termination near the part
number, and gently pry up only the top cover from the P6022 termination by
twisting the screwdriver. Leave the bottom cover on, as it must remain in
place when
ever the termination is in use.
2. Set up the oscilloscope as described below:

6. Connect the probe to the current probe calibration fixture. The figure below
shows t
he proper probe orientation to the current probe calibration fixture.

Do not immerse the probe in liquids or use abrasive cleaners.
Do not lubricate the jaws mating surfaces. Any lubricant between the core pieces
should be removed with a recommended solvent.
Do not use a petroleum based lubricant on the plastic. If the plastic slide assembly
requires lubrication, use a silicone-based grease sparingly.
When cleaning the probe, look for any excessive wear of the slide parts that might
cause the probe to operate improperly. Dirty or worn mating surfaces between
the transformer and the lid can degrade low-frequency response. Clean these
surfaces if necessary.
