RIGOL
Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected
by qualif ied servic e p er so n nel 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 RMS). The RP1001C current probe can also make AC and
DC measurements with a multimeter by using the BNC-to-banana
plug adapter.

.
Zero adjustment: After connecting to
power and fixing the current probe to a
fixed position, rotate the knob to adjust
the probe output tothe pr oper DC off set. 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,

The red overload

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.
RP1001C User’s Guide 1
RIGOL
Note: when measuring DC signals, accurate DC value is
possible only when the current probe is fixed at a certain
position, 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 i n the figure
below.
Figure 2 Connection between the Test Clamp and Conductor

RIGOL
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 coupli ng
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 thr ough 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.

RIGOL
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 three screws on the rear cover and take off the
rear cover . Y ou can see the location of the battery and remove
the battery.
3 While observing polarity, install the new
corresponding location.
4 Install the rear cover.

RP1001C User’s Guide 5
RIGOL
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 t he 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 abr asives. 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 stur dy shipping carton ha ving 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.

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 pro duct is
out of service.
