This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your Fluke I1000S AC Current Probe.
2. Key Features
- Accurate measurement of currents from 100 mA to 1000 A rms.
- Wide frequency range from 5 Hz to 100 kHz.
- Non-intrusive measurement without breaking the circuit.
- Integrated passive filter to eliminate noise and ringing on rapidly rising di/dt waveforms, ensuring clear oscilloscope displays.
- Direct connection to oscilloscopes via a reinforced coaxial cable and insulated BNC connector.
- Compatibility with multimeters using an optional PM9081/001 BNC/Banana adapter.
- Safety rating: CAT III, 600 V.
3. Setup
Before using the Fluke I1000S, ensure all connections are secure and the probe is clean.
- Connect to Oscilloscope: Connect the BNC connector of the probe's coaxial cable directly to the input channel of your oscilloscope. Ensure the connection is firm.
- Connect to Multimeter (Optional): If using with a multimeter, attach the optional PM9081/001 BNC/Banana adapter to the probe's BNC connector, then connect the banana plugs to the appropriate input jacks on your multimeter.
- Select Range: Use the selector switch on the probe body to choose the appropriate current range (10 A, 100 A, or 1000 A) based on the expected current of the circuit being measured.
- Power On: Ensure your connected measurement device (oscilloscope or multimeter) is powered on and configured for current measurement.
4. Operating Instructions
Follow these steps for accurate current measurement:
- Safety First: Always ensure the circuit is de-energized or appropriate safety precautions are taken before clamping the probe around a conductor. Observe the CAT III, 600 V safety rating.
- Open Clamp: Press the lever on the probe to open the clamp jaws.
- Encircle Conductor: Carefully place the open jaws around a single conductor carrying the AC current you wish to measure. Ensure the jaws close completely around the conductor. Do not clamp around multiple conductors if you intend to measure the current in only one.
- Select Range: Verify that the selected range on the probe (10 A, 100 A, or 1000 A) is suitable for the expected current. Start with a higher range if unsure to prevent overloading.
- Read Measurement: Observe the current reading on your connected oscilloscope or multimeter. The probe outputs are 100 mV/A, 10 mV/A, and 1 mV/A for the 10 A, 100 A, and 1000 A ranges respectively. Adjust your measurement device's settings as needed to interpret the output correctly.
- Disconnect: After measurement, open the clamp jaws and remove the probe from the conductor. Disconnect the probe from your measurement device.
Note: The passive filter helps in obtaining clean waveforms, especially for distorted signals and harmonics. Ensure proper grounding of your oscilloscope for optimal performance.
5. Maintenance
Proper maintenance ensures the longevity and accuracy of your Fluke I1000S probe.
- Cleaning: Clean the probe's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the jaws are free of dust and debris to maintain proper closure.
- Storage: Store the probe in a clean, dry environment, away from extreme temperatures and direct sunlight. Keep the jaws closed when not in use to protect the internal components.
- Inspection: Periodically inspect the coaxial cable and BNC connector for any signs of damage, such as cuts, fraying, or bent pins. Do not use the probe if the cable or connector is damaged.
- Calibration: While the probe is designed for long-term stability, periodic calibration by a qualified service center is recommended to ensure continued accuracy, especially in critical applications.
