Fluke I3000 FLEX-4PK AC Current Clamp, 600V Voltage, 3000A AC rms Current (Pack of 4)

The i3000s Flex is an AC current clamp utilizing the Rogowski principle. It can be used to measure currents up to 3000A 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. Three ranges: 30A, 300A and 3000A, 1, 10 or 100 mV/A output. Ideal for current measurement on thick and hard to reach conductors without breaking the circuit. Maximum conductor diameter 178mm. CAT III 600V safety rating. Current ranges: 30A, 300A, 3000A AC rms. Output sensitivity (AC-coupled): 100 mV, 10 mV, 1 mV per A. Load impedance: 100 kilo ohm minimum. Accuracy at +25 degree C: +/-1 percent of range (45 Hz to 65 Hz). Linearity 10 to 100 percent of range: +/-0.2 percent of reading. Noise: 8 mV AC rms (30 A), 2 mV AC rms (300A, 3000A). Frequency range: 10 Hz to 50 kHz (-3 dB). Phase error: less than +/-1 degree (45 Hz to 65 Hz), +/-10 degree (at 20 kHz). Position sensitivity with cable greater than 25 mm from the coupling: +/-2 percent of range. External field with cable greater than 200 mm from the head: +/-1 percent of range. Power supply: 2 x AA/MN 1500/LR6 Alkaline, 400 hours, low battery indicator or dedicated external power supply. Temperature coefficient: +/-0.08 percent of reading per degree C. Working voltage: 600V AC rms or DC. Head circumference: 610mm. Head cable diameter: 14.3mm. Head bend radius: 38.1mm. Cable length (head to electronics): 2m. Output connection: 0.5m cable terminated with safety BNC connector. Supplied with 4mm safety plug adapter. Operating temperature range: -20 to +90 degree C (-4 to 190 degree F) (head), -20 to +85 degree C (-4 to 185 degree F) (electronics). Storage temperature range: -40 to +105 degree C (-40 to 221 degree F) (head), -20 to +85 degree C (-4 to 185 degree F) (electronics). Operating humidity: 15 to 85 percent (non-condensing).
