(R) i6000s Flex AC Current Probe Instruction Sheet Introduction The i6000s 24 Flex and i6000s 36 Flex AC Current Probes (hereafter referred to as "the Probes") are used with oscilloscopes, digital multimeters, recorders or data loggers. The Probes can be used to measure AC current up to 6000 A. The flexible measuring head allows current measurements on conductors that are hard to reach or inaccessible using typical clamp-on current probes. The Probes provide a low-voltage (3 V ac) output that is proportional to the current being measured. The Probes provide full-scale direct readings for 60 A, 600 A, and 6000 A.

A Caution identifies conditions and actions that may damage the calibrator or the test instruments. WX Warning To avoid electric shock or personal injury: * If the Probes are used in a manner not specified in these operating instructions, protection provided by the Probes may be impaired. * Use the Probes only if qualified. * Use caution during installation and use of the Probes; high voltages and currents may be present in circuit under test. * Have maintenance performed by only qualified service personnel. * Protect the Probes against water and humidity. * Wear protective clothing and gloves as required. * Do not install this product on live conductors. Always de-energize the circuit under test before installing the flexible measuring head. * Always inspect the electronics unit, connecting cable, and flexible measuring head for damage before using the Probe. * Do not use the Probe if damaged. * Always connect Probe to display device before installing the flexible measuring head. * Never change batteries while measurement head is installed on conductor. * Never connect or disconnect the external power supply while the measurement head is installed on a conductor. * Use only the provided original or specified accessories. * Adhere to local and national safety codes. Individual protective equipment must be used to prevent shock and arc blast injury where hazardous live conductors are exposed. * CAT III equipment is designed to protect against the transients in the equipment in fixed equipment installations, such as distribution panels, feeders and short branch circuits, and the lighting systems in large buildings. i6000s English Instruction Sheet Page 3 Specifications Electrical Characteristics Current Ranges Output Sensitivity (AC Coupled) Load Impedance Accuracy (at 25 C) Linearity (10 % to 100 % of range) Noise Frequency Range Phase error Position sensitivity (with cable > 25 mm from the coupling) External field (with cable >200 mm from the head) Power Supply Temperature Coefficient Working Voltage 60 A / 600 A / 6000 A ac rms 50 mV / 5 mV / 0.5 mV per A 100 k minimum 1% of range (45 - 65 Hz) 0.2 % of reading 8 mV ac rms (60 A) 2 mV ac rms (600/6000 A) 10 Hz to 50 kHz (- 3 dB) < 1 (45 - 65 Hz), 10 (at 20 kHz) 2 % of range 1 % of range 2 x AA MN 1500 LR6 Alkaline 400 hours, low battery indicator or dedicated ext power supply 0.08 % of reading per C 600 V ac rms or dc i6000s English Instruction Sheet Page 4 General Characteristics Head Cable Length (double insulated) Cable Diameter Bend Radius Cable Length Output Connection Operating Temperature Storage Temperature Operating Humidity Weight 610 mm (24 in.) i6000s Flex-24 915mm (36 in.) i6000s Flex-36 14.3 mm (0.562 in) 38.1 mm (1.5 in) 2 m long (78.7 in) (head to electronics) 0.5 m cable terminated with safety BNC connector Supplied with 4 mm safety plug adapter - 20 C to +90 C (-4 to 194 F) (head) - 20 C to +85 C (-4 to 185 F) (electronics) - 40 C to +105 C (-40 to 221 F) (head) - 20 C to +85 C (-4 to 185 F) (electronics) 15 % to 85 % (non-condensing) 180 g (head), 190 g (electronics) Safety Standards EN 61010-1: 2001 EN 61010-2-032: 2002 EN 61010-031: 2002 600 V rms Category III, Pollution Degree 2.

The Probe requires two AA/MN1500/LR6 alkaline batteries for operation. The battery compartment is accessed from the rear end of the electronic enclosure. The batteries must be replaced when the LED is lit continuously or when it fails to light up. Ensure that the Probe is away from any current carrying conductor and also that the output is disconnected from other equipment. To install the battery: 1. Use a coin or a similar tool to turn the battery lock (1/4 turn) until the dot aligns with the unlock symbol. 2. Remove the battery cover. 3. Install the batteries ensuring that correct polarity is observed. 4. Replace the battery cover and turn the battery lock until the dot aligns with the lock symbol. External Power Supply An optional Class II external power supply is available from Fluke. The power supply is designed to ensure that the Probe continues to meet its specified safety standards. The usage of a power supply from another vendor is not recommended. XWWarning To avoid electric shock or injury, remove Probe and all other connections from energized circuits before connecting external power supply to the instrument. Measuring Current XWWarning * To avoid electric shock or injury, read Safety Instructions before operating this product * Ensure that the conductor to be tested is deenergized To measure current: 1. Connect the output of the electronics to the input of an oscilloscope or other data recording device. i6000s English Instruction Sheet Page 7 XWWarning To avoid electric shock or injury, the flexible current Probes are not for use on conductors with a potential of over 600 V. 2. Wrap the flexible measuring head around the conductor to be tested in a close coupling manner. 3. Energize the circuit under test. 4. For most accurate measurement, centre the flexible head around the conductor. 5. Locate coupling away from the nearby conductors. WX Warning To avoid electric shock or injury: * Do not use the flexible current Probes to measure bare conductors unless wearing protective clothing suitable for high voltage work. * Always use appropriate equipment for personal protection. When installed on bare conductors/busbars, the product must be within a suitable enclosure. Ieb0001.eps Operation To activate the unit, move the switch from `Off' position to the required measuring range. If the value of current being measured is unknown, select the 6000 A current range and then reduce accordingly. i6000s English Instruction Sheet Page 8 Battery Status Battery status is indicated by an LED on the front of the Probes. This LED will flash one time when the unit is activated. The length of time the LED is lit will increase as battery life decreases. Momentary lighting of LED indicates batteries are good. Continuous lighting of LED indicates low battery and requires replacement at the earliest. No lighting of LED indicates batteries are dead and require replacement immediately. Maintenance WX Warning To avoid electric shock or injury: * Do not use Probes if damaged. * Always inspect the electronics unit, connecting cable, and flexible measuring head for damage before use. * To avoid electric shock, keep the Probes clean and free of surface contamination. Use Isopropyl alcohol to clean the control unit and measuring head. Make sure that the flexible measuring head, connecting cable, and electronic enclosure are dry before further use.
