RP1002C User's Guide I RIGOL 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 specif ied by this manual. Ground The I nstrument. 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 f ire 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 the instrument with covers or panels removed. Avoid Circuit or Wire Exposure. Do not touch exposed junctions and components when the unit is powered. II RP1002C User's Guide RIGOL Do Not Operate With Suspected Failures. I f you suspect damage occurs to the instrument, have it inspected by qualif ied 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. I nadequate 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. I n 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. I n order to avoid damages to the device or personal injuries, it is important to operate the device away from an explosive at m ospher e. Keep Product Surfaces Clean and Dry.

The RP1002C 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 f ixing the current probe to a f ixed position, rotate the knob to adjust the probe output tothe proper DC offset. I t 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 pr esent ) . Range sw itch: Slide the switch from OFF to either the 50 mV/ A or 500mV/ A range. When 50 mV/ A or 500mV/ A is selected, the probe is turned on, and the green battery indicator (ON) lights. Pow er Supply indicator: The green power supply indicator lights when the probe is turned on. For more information, please refer to To I nstall 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. 2 RP1002C User's Guide Basic Operation RIGOL Before using the current probe, the battery or specif ied AC power adapter must be installed. For the battery installation instructions, refer to To I nstall the Battery. CAUTI ON Do not clamp the probe onto circuits with voltages greater than 600 VAC. Otherwise, personal injury or damage to the probe may result. CAUTI ON Always connect the RP1002C current probe output to the instrument before clamping onto the circuit under test. Connection betw een the Current Probe and Oscilloscope 1 Set the coupling mode of the oscilloscope to DC and connect the BNC interface of the RP1002C current probe to the oscilloscope input via dual-BNC coaxial cable. 2 Move the Range switch to the 50 mV/ A or 500 mV/ A position to turn on the RP1002C 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. RP1002C User's Guide 1 RIGOL Note: when measuring DC signals, accurate DC value is possible only when the current probe is f ixed 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 in the f igure below. Figure 2 Connection between the Test Clamp and Conductor 2 RP1002C User's Guide 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 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 (50 mV/ A or 500 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 f igure on the next page shows the difference between the line current drawn by a resistive load and a motor controller. Figure 3 Typical Current Waveforms RP1002C User's Guide 3 RIGOL Connection betw een the Current Probe and Digital Meter Connect the BNC connector of the RP1002C 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 RP1002C current probe, loop additional turns of the wire under test through the test clamp. The sensitivity of the RP1002C current probe is multiplied times the number of loops in the test clamp, for example, 50 mV/ A X 4 turns = 200 mV/ A. 4 RP1002C User's Guide M a int ena nce Ba t t er y RIGOL 1 The RP1002C current probe uses a single square 9 V battery. This instrument is a high power product. Please use the specif ied alkaline battery. 2 As the battery in the RP1002C current probe is drained, signif icant measurement errors may occur. The green battery indicator will continue to light until a low battery voltage of 6.5 V is reached. Battery RP1002C User's Guide 5 RIGOL To I nstall 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. You can see the location of the battery and remove the battery. 3 While observing polarity, install the new alkaline battery at the corresponding location. 4 I nstall the rear cover. AC Pow er Adapter 1 The specif ied 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. 6 RP1002C User's Guide Cleaning RIGOL 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. I f the original packaging is unf it 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. RP1002C User's Guide 7 RIGOL Specif ica t ions These characteristics apply to an adjusted RP1002C current probe installed on an oscilloscope of any brand. The oscilloscope must be warmed up for at least 20 minutes and be in an environment with the temperature at 10-30 and the humidity at 0-80% .
