General Safety Summary
Please review the following safety precautions carefully before putting
the instrument into operation so as to avoid any personal injuries or
damages to the instrument and any product connected to it. To
prevent potential hazards, please use the instrument only specified by
this manual.
Ground The Instrument.
The instrument is grounded through the Protective Earth lead of the
power cord. To avoid electric shock, it is essential to connect the earth
terminal of power cord to the Protective Earth terminal before any
inputs or outputs.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratings and markers on the
instrument and check your manual for more information about ratings
before connecting.
Replace Fuse Properly.
Make sure that no overvoltage (such as voltage caused by
thunderbolt) this product. Otherwise, the operator might be exposed
to electric shock.
Do Not Operate Without Covers.

Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by
qualified service personnel before further operations. Any maintenance,
adjustment or replacement especially to circuits or accessories must be
performed by RIGOL authorized personnel.
Keep Well Ventilation.
Inadequate ventilation may cause increasing of temperature or
damages to the device. So please keep well ventilated and inspect the
intake and fan regularly.
Do Not Operate in Wet Conditions.
In order to avoid short circuiting to the interior of the device or
electric shock, please do not operate in a humid environment.
Do Not Operate in an Explosive Atmosphere.
In order to avoid damages to the device or personal injuries, it is
important to operate the device away from an explosive atmosphere.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in air, please keep the
surface of device clean and dry.
Electrostatic Prevention.
Operate in an electrostatic discharge protective area environment to
avoid damages induced by static discharges. Always ground both the
internal and external conductors of the cable to release static before
connecting.

RP1001C Overview
The RP1001C current probe enables a general purpose oscilloscope to
display AC and DC current signals up to 100 A Peak (70 A R M S). The
RP1001C current probe can also make AC and DC measurements
with a multimeter by using the BNC-to-banana plug adapter.

Control/Indicator Description
Current flow symbol: The arrow shows
the positive direction of current flow.
Zero adjustment: After connecting to
power and fixing the current probe to a fixed
position, rotate the knob to adjust the probe
output to the proper DC offset. 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).
Range switch: Slide the switch from OFF to
either the 10 mV/A or 100mV/A range. When
10 mV/A or 100mV/A is selected, the probe
is turned on, and the green battery indicator
(ON) lights.
Battery indicator: The green
battery/power indicator lights when the
probe is turned on. For more information,
please refer to To Install the Battery.
Overload indicator: The red overload
indicator lights and flicks continuously if the
measured signal is greater than the
maximum range of the selected range
capacity.

Basic Operation
Before using the current probe, the battery or specified AC power
adapter must be installed. For the battery installation instructions,
refer to To Install the Battery.
CAUTION
Do not clamp the probe onto circuits with voltages greater
than 600 VAC. Otherwise, personal injury or damage to the
probe may result.
CAUTION
Always connect the RP1001C current probe output to the
instrument before clamping onto the circuit under test.
Connection between the Current Probe and Oscilloscope
1 Set the coupling mode of the oscilloscope to DC and connect the
BNC connector of the RP1001C current probe to the oscilloscope
input via dual-BNC coaxial cable.
2 Move the Range switch to the 10 mV/A or 100 mV/A position to
turn on the RP1001C current probe. At this point, the green
battery indicator lights.
3 Use the zero adjustment knob to adjust the probe to the proper
DC offset.
Note: when measuring DC signals, accurate DC value is possible
only when the current probe is fixed at a certain position,
RP1001C User’s Guide 3
RIGOL
otherwise, the change of the position of the probe will cause the
DC drift. When measuring AC signals, users can move the current
probe.
4 Before connecting the current probe to circuit, open the test
clamp and clamp it onto the conductor as shown in the figure
below.
Figure 2 Connection between the Test Clamp and Conductor
5 Adjust the probe channel and oscilloscope as necessary to get a
clear and stable view of the signal. At this point, you can see both
the current components of AC and DC. Set the coupling mode of
the oscilloscope to AC to see the current components of AC. The
operation method of the current components of AC is the ratio of
the voltage amplitude measured through the oscilloscope and
the switch range currently selected of the current probe (10
mV/A or 100 mV/A).
Note: The current drawn by different devices look much different
than that of others. While the RMS current can only be used in
low frequency current, the momentary peaks may be quite high.
The figure on the next page shows the difference between the
line current drawn by a resistive load and a motor controller.

Connection between the Current Probe and Digital Meter
Connect the BNC connector of the RP1001C current probe and the
input terminal of the digital meter using the BNC-to-banana plug
adapter provided with the accessories.
To measure only AC current, select the AC volts of the meter. To
measure DC current, select the DC volts of the meter, and adjust the
probe output to the proper DC offset. When connecting the current
under test, please note the current convention arrow on the test
clamp to get the proper polarity reading.
Note: To increase the measurement sensitivity of the RP1001C
current probe, loop additional turns of the wire under test through the
test clamp. The sensitivity of the RP1001C current probe is multiplied
times the number of loops in the test clamp, for example, 10 mV/A X
4 turns = 40 mV/A.

Maintenance
Battery
1 The RP1001C current probe uses a single square 9 V battery.
This instrument is a high power product. Please use the specified
alkaline battery.
2 As the battery in the RP1001C current probe is drained,
significant measurement errors may occur. The green battery
indicator will continue to light until a low battery voltage of 6.5 V
is reached.
To Install the Battery
1 Remove the test clamp from the circuit.
2 Remove the screw on the battery compartment cover at the rear
panel of the probe and then remove the battery compartment
cover.
3 While observing polarity, install the alkaline battery at the
corresponding location.
4 Install the battery compartment cover.

AC Power Adapter
1 The specified AC power adapter can be used to avoid
measurement error due to poor battery durability.
2 When using an AC power adapter for an extended time, you are
recommended to remove the battery. This is because heating will
result in battery leakage, and battery electrolyte will rust the
circuit board, thus creating major damage. Furthermore, as
batteries are high pollution products, you are recommended to
avoid using them as far as possible.
Cleaning
To clean the probe exterior, use a soft cloth dampened in a solution of
mild detergent and water. To clean the core, open the test clamp and
clean the exposed core surfaces with a cotton swap dampened with
isopropyl alcohol (isopropanol). Lubricate the clamp mating surfaces
with light oil.
Note: Do not clean with solvents or abrasives. Do not immerse the
probe.

Preparation for shipment
A special box is provided to be used for this product, convenient for
storage and shipment. Please do not discard it. If the original
packaging is unfit for use or not available, use the following
packaging guidelines.
1 Use a sturdy shipping carton having inside dimensions at least
one inch greater than the probe dimensions.
2 Put the probe into a plastic bag or wrap to protect it from
dampness.
3 Place the probe into the box and stabilize it with light packaging
material.
4 Seal the carton with shipping tape.
