CHAPTER 2
PRODUCT FEATURES
2.1 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.
2.2 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 1M
Ω
