sensor is locked and at this point, the UNLOCK indication is
covered (cannot be seen).

For RP1005C, there are LOCK and UNLOCK indications on the slide

switch. The current sensor is locked when the LOCK indication is
displayed on the slide switch (the UNLOCK indication disappears).

2． Current Sensor

It is used to clamp the co nductor to be measured and carries out
the actual current measurement. It is a precision assembly
including a molded component, a ferrite core and a Hall effect
element. It may be damaged if subjected to sudden changes in
ambient temperature, or mechanical strain or shock, and
therefore great care should be taken in handling it.

3． Demagnetizing Switch

It is used to demagnetizing the core if it has been magnetized by
switching the power on and off, or by an excessive input. Always
carry out demagnetizing before measurement. The demagnetizing
process takes about one second. During demagnetizing, the
current probe outputs a demagnetizing waveform.

4． Zero Adjustment Dial

Use the zero adjustment dial to correct for the effect of a DC

voltage offset or temperature drift on t he dev ice. W hen b egin nin g
measurement, after demagnetizing always carry out zero
adjustment to adjust the baseline to zero.

5． Coarse Adjustment Trimmer (only applicable to RP1003C

and RP1004C)

When adjustment is not possible within the range of zero
adjustment dial, use a nonconductive screwdriver to (such as

RIGOL

6 RP1003C/RP1004C/RP1005C User’s Guide

ceramic screwdriver) to adjust the baseline to the adjustable
range of the zero adjustment dial via the coarse adjustment
trimmer; then, use the zero adjustment dial to adjust the baseline
to zero.

6． Output Connector

This connector can be directly connected to the BNC input terminal
of the measuring instrument (such as oscilloscope or recorder), or
be connected to other measuring instrument via BNC-to-Banana
plug adaptor or similar adaptor. At this point, the current
waveform of the conductor under measurement is output at a
constant gain.
Note:
a) For RP1003C and RP1004C, 0.1V/A on the output connector i s

the gain when the input impedance of the measuring
instrument is 1MΩ; the corresponding gain is
1/2×0.1V/A=0.05V/A when the input impedance of the
measuring instrument is 50Ω.

a) For RP1005C, 0.01V/A on the output connector is the gain

when the input impedance of the measuring instrument is
1MΩ; the corresponding gain is 1/2×0.01V/A=0. 005V/A when
the input impedance is 50Ω.

7． Power Plug

Connect the power plug to the corresponding receptacle of the
power adaptor to supply power to the current probe terminator.
Note: To avoid electric shock, do not touch the portion beyond the
protective barrier during use.

RIGOL

RP1003C/RP1004C/RP1005C User’s Guide 7

To Use the Current Probe

Before using the current probe to measure the current of the device
under measurement, make measurement preparations and perform
demagnetizing and zero adjustment. Then, make measurements
according to the method described in Measurement Steps.
Note: You are recommended to read the Precautions during
Measurements before making measurements to avoid unnecessary
loss.

Measurement Preparations

1. Connect the power plug of the current probe to the power
adaptor.

2. Turn off the power adaptor and connect it to the power supply.
Note: The voltage of the power supply used should match the
rated supply voltage of the power adaptor.

3. Turn on the power adaptor and check whether the powe r indicator
lights.

Power Indicator

RIGOL

8 RP1003C/RP1004C/RP1005C User’s Guide

Demagnetizing

The core can be magnetized by switching the power on and off, or by
an excessive input. Therefore, perform demagnetizing before making
measurements.

1. With the input of the measuring instrument at ground, set the
coupling of the measuring instrument to GND and adjust the
baseline to the zero position.

2. Set the coupling of the measuring instrument to DC.

3. Connect the output connector of the current probe to the BNC
input terminal of the measuring instrument. Turn the collar of the
output connector as show n in the figur e below and check w hethe r
it is locked securely.

Note: When disconnecting the output connector and the
measuring instrument, be sure to release the lock by rotating the
collar in the opposite direction of the arrow as shown in the figure
above before pulling off the connector. Forcibly pulling the
connector without releasing the lock or pulling on the cable can
damage the terminator.

4. Make sure the current sensor is locked (for RP1003C and RP1004C,

Collar

RIGOL

RP1003C/RP1004C/RP1005C User’s Guide 9

the slide switch should be at the LOCK position; for RP1005C,
LOCK should be displayed on the s li de switch a nd UNLOCK should
disappear.

5. Turn on the power adaptor and press the demagnetizing switch on
the terminator. The demagnetizing process takes about one
second. During the demagnetizing, the current probe outputs a
demagnetizing waveform.

Note: Do not demagne tize the curr ent prob e when it is cl amping a

conductor to be measured. Demagnetizing causes current to flo w
into the conductor, which may damage the parts in the circuit to
be measured.

Zero Adjustment

As the voltage offset and temperature drift might affect the position of
the baseline of the current probe, perform zero adjustment after
performing demagnetizing when beginning measurements.

1. Turn the zero adjustment dial on the terminator to adjust the
baseline to the zero position.

2. When adjustment is not possible within the range of zero
adjustment dial, use a nonconductive screwdriver to (such as
ceramic screwdriver) to adjust the baseline to the adjustable
range of the zero adjustment dial via the coarse adjustment
trimmer; then, use the zero adjustment dial to adjust the baseline
to the zero position (only applicable to RP1003C and RP1004C).

Measurement Steps

Make measurements after the above operations are finished.

1. Open the current se n s or by pushing the slide switch in the
direction of the arrow as shown in the figure below (for RP1003C
and RP1004C, the slide switch sho uld be at the OPEN position; for
RP1005C, UNLOCK should be displayed on the slide switch and
LOCK should disappear).

2. Align the current sensor so that the current direction indication
corresponds to the direction of current flowing through the

Slide Switch

RIGOL

RP1003C/RP1004C/RP1005C User’s Guide 11

conductor to be measured. Clamp the conductor to be measured
so that the conductor is in the center of the sensor aperture.

3. Lock the current sensor by pushing the slide switch in the direction
of the arrow as shown in the figure below (for RP1003C and
RP1004C, the slide switch should be at the LOCK position; for
RP1005C, you need to first press the current probe to close the
current sensor and then push the slide switch until LOCK is
displayed and UNLOCK disappears).

4. At this point, you can view the voltage amplitude of the waveform
measured by the measuring instrument and calculate the actual
current amplitude (current amplitude=voltage amplitude
measured/gain of the current probe). For example, when the
voltage amplitude measured is 2V and the gain of the current
probe is 0.1V/A, the actual current am plitude is 2V/(0.1V/A)=20A.

Note: The current sensitivity can be derived from the volta g e
sensitivity of the measuring instrument. The current sensitivity
equals the ratio of the voltage sensitivity of the measuring
instrument to the gain of the current probe. For example, when
the voltage sensitivity of the measuring instrument is 0.001V/div

Slide Switch

I

Current Direction
Indication

RIGOL

12 RP1003C/RP1004C/RP1005C User’ s Guide

and the gain of the curren t probe i s 0.1V/A, the current sensitivity
is (0.001V/div)/(0.1V/A)=0.01A/div.

Precautions during Measurements

1. The curre nt consumption of the current probe depends on the
current to be measured. Make sure that the total current
consumption of the current probes do not exceed the rated output
current of the power adaptor when multiple current probes are
connected to the same power adaptor. The figure below is the
relation curve between the output current and current
consumption.

Note: The current consumption is the a lgebraic sum of the positive
and negative current consumption.

2. The maximum continuous input range is bas ed on the heat that is
internally generated during the meas ureme nt. Note that the inp ut
current should not exceed this range; otherwise, the current probe
might be damaged.

RIGOL

RP1003C/RP1004C/RP1005C User’s Guide 13

3. The linear response range of the input current varies according to
the frequency of the current being measured. For the variation
relation curve between them, refer to Appendix 2 Relation
between Max Input Current and Frequency.

4. If excess current is input, generated heat activates a built-in safety
function that blocks normal output. If this happens, disconnecti ng
the current sensor and the conductor under measurement or
reduce the input current to zero. Wait until the current sensor has
had sufficient time to cool before resuming operation.
Note: Even if the input current does not exceed the maximum
continuous input range, continuous input for an extended period
of time may result in activation of the safety circ uit to prevent
damage resulting from heating of the current sensor.

5. At high ambient temperatures, the built-in safety circuit may
activate at current input levels below the maximum continuous
input range.

6. Continuous input of current exceeding the maximum continuous
input range or repeated safety circuit activation will degrade the
performance of the safety circuit, possibly resulting in damage to
the device.

7. Do not place any unclamped conductor with an electric current of
a frequency of 10kHz or higher near t he current senso r (as shown
in the figures on the next page). Current flowing in the conductor
nearby may heat up the sensor and cause its temperature to rise,
leading to damage to the current sensor.

8. Be sure to use the sl id e switch to open the current sen s or . For
RP1003C and RP1004C, please do not press the upper core in the
direction of the arrow as shown in the figure below to avoid
damaging the internal structure of the slide switch.

9. Immediatel y aft er po w er ing on , the device may b e subject to an
appreciable DC drift due to the effect of self-heating. To
counteract this, allow the current probe to warm up for more tha n
30 minutes before carrying out measurements.

10. Under certain circumstances, oscillation may occur when the
probe is connected to the power adaptor when the power supply is
on. This does not indicate a malfunction. Oscillation can be
stopped and operation restored to normal by opening and closing
the current sensor.

11. When the frequency of the input signal is relatively high, the
common mode voltage range corresponding to the signal
measured by the current probe reduces. At this point, connect the
current probe to the low-voltage side of the circuit, as shown in
the figures on the next page.
