The i6000sflex is an AC current probe utilizing the Rogowski principle. It can be used to measure currents up to 6000A when used in conjunction with oscilloscopes, recorders or data loggers. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas. Current ranges: 60A/600A/6000A AC rms. Output sensitivity (AC coupled): 50 mV /5mV / 0.5mV per A. Load impedance: 100 k ohm minimum. Accuracy (at +25 degree C): +/-1 percent of range (45 - 65 Hz). Linearity (10 to 100 percent of range): +/-0.2 percent of reading. Noise: 8mV AC rms (60 A), 2 mV AC rms (600/6000A). Frequency range: 10 Hz to 50 kHz (- 3 dB). Phase error: 25mm from the coupling): +/-2 percent of range. External field (with cable > 200mm from the head): +/-1 percent of range. Power supply: 2 x AA MN 1500 LR6 alkaline 400 Hours, low battery indicator or dedicated ext power supply. Temperature coefficient: +/-0.08 percent of reading per degree C. Working voltage: 600 V AC rms or DC. Head cable diameter: 14.3mm. Cable length (head to electronics): 2 meters. Operating temperature range: -20 to +90 degree C (head), -20 to +85 degree C (electronics). Storage temperature range: -40 to +105 degree C (head), -20 to +85 degree C (electronics). Operating humidity: 15 to 85 percent (non condensing).
