Page 4: Introduction
Read the instruction completely. • Use caution on any circuit: potentially high voltages and currents may be present and may pose a shock hazard. • Do not use the probe if damaged. Always connect the current probe to the measuring device before it is connected around the conductor • Do not use on non insulated conductor with a potential to ground greater than 600V CAT III pollution 2. Use extreme caution when clamping around bare conductors or bus bars. • Before each use, inspect the probe; look for cracks in housing or output cable insulation. • Do not use clamp in wet environment or in locations that hazard- ous gases exist. • Do not use the probe anywhere beyond the tactile barrier.

CHAPTER 2 PRODUCT FEATURES Description The AC Current Oscilloscope Probe Model SR661 expands oscilloscope applications in industrial or power environments, and is ideal for analysis and measurement of distorted current waveforms and harmonics. The Model SR661 permits accurate display and measurement of currents from 100mA to 1000Arms, 1Hz to 100kHz (with current derating) without breaking into the circuit. A passive filter eliminates noise, ring on rapid rising (di/dt) waveforms, and ensures accurate screen displays. The probe connects directly to an oscilloscope through an insulated coax- ial cable with an insulated BNC. Compatibility The Model SR661 is compatible with any analog or digital oscilloscope or other voltage-measuring instrument which has the following features: • BNC input connector • Range capable of displaying 0.2 to 0.5V per division, or 2V range • Minimum input impedance of 1MΩ AC Current Oscilloscope Probe Model SR661... -

Page 15: Operation
CHAPTER 4 OPERATION Current Measurement WARNING: Always connect the probe to the instrument before clamping onto the circuit under test. • Connect the Model SR661 to the proper input channel on the oscilloscope. • Begin with the least sensitive range on the current probe (1mV/A) • Select the 0.5V/Division range on the oscilloscope. • Clamp the probe on the conductor to be measured and read the current flowing directly on your oscilloscope. -
Page 16: Maintenance
• Disconnect the unit from all circuits and test cables before open- ing the case. • Use caution with metallic tools that may short battery packs, power supplies, etc. Cleaning • To clean the probe body, use a soft cloth dampened in a solution of mild detergent and water. To clean the core, open the jaw and clean the exposed core surfaces with a cotton swab dampened with isopropyl alcohol (isopropanol) or ethyl alcohol (fotocol or ethanol). Lubricate the jaws mating surfaces with a light oil. • Do not use chemicals containing benzine, benzene, toluene, xylene, acetone, or similar solvents. • Do not immerse the probe in liquids or use abrasive cleaners.
