Page 6: Product Features
CHAPTER 2 PRODUCT FEATURES Description The AC Current Oscilloscope Probe Model MN261 expands oscilloscope applications in industrial or power environments, and is ideal for analysis and measurement of distorted current waveforms and harmonics. The Model MN261 permits accurate display and measurement of currents from 0.1 to 240Arms, 40Hz to 10kHz (with current derating) without break- ing 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 MN261 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 MN261 ShopAEMC www. .com 1.888.610.7664 Shop for AEMC products online at:... -

(Remember to unclamp the probe from the conductor before disconnect- ing it from your meter or instrument.) You may also use your oscilloscope to amplify the signal while using the 1mV/A probe range (which offers the best accuracy and least phase shift). NOTE: It is possible to change the range on the current probe with- out removing the probe from the current carrying conductor, but it is important to remember not to exceed the permissible peak ratings of 340mV peak or 680mV peak to peak maximum. The peak ratings by range are: 34A peak @ 100mV/A and 340A peak @ 10mV/A. AC Current Oscilloscope Probe Model MN261 ShopAEMC www. .com 1.888.610.7664 Shop for AEMC products online at:... -
Page 13: Maintenance
• To avoid electrical shock and/or damage to the instrument, do not allow water or other foreign substances into the case. • 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 or ethyl alcohol. 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.
