Overview Fluke Loop Calibrator. This feature-rich solution to loop calibration, maintenance and repair offers: A large display and simple, pushbutton interface for ease of use. Simultaneous mA and % readout for quick, easy interpretation of readings. mA accuracy of 0.02% Push button 25% steps for fast, easy linearity checks. Save time over traditional knob type controls. "Span Check" for fast confirmation of zero and span. Selectable slow ramp, fast ramp, and step to provide smooth outputs for valve slewing and loop functional tests. 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM. Single 9V battery that is easily changed. 0 - 20 mA or 4 - 20 mA default start up modes. mA sourcing, simulation and measurement 0.02% accuracy and 0.001 mA resolution Simultaneous mA and % of span display Selectable step or ramp outputs 24 V Loop supply with mA measure 0-28 VDC measurement to check Loop Voltage Easy battery exchange without opening the case Compact case with separate protective holster Three year warranty Includes AC70A Alligator Clips C10 protective yellow holster with Flex-Stand™ Instruction sheet TL75 safety-designed test lead set NIST- traceable calibration report and data Specifications Specifications Current measurement Range 0 to 24 mA Resolution 0.001 mA Accuracy 0.02% Rdg + 2 LSD Current sourcing Range 0 to 20 mA or 4 to 20 mA Accuracy 0.025% Rdg + 2 LSD Drive capability 1000 Ω @ 24 mA Current simulation Range 0 to 20 mA or 4 to 20 mA Accuracy 0.025% Rdg + 2 LSD Ext. loop voltage requirement 12-30 V Loop power While measuring mA, 24 V Voltage measurement Range 0 to 28 V DC Resolution 1 mV Accuracy 0.025% Rdg + 2 LSD Environmental Specifications Operating temperature -10°C to 55°C Storage temperature -40°C to 60°C Humidity (without condensation) 0 to 90% (0°C to 35°C); 0 to 70% (35°C to 55°C) Temperature coefficient -10°C to 18°C, 28°C to 55°C, ±.005% of range per°C Safety Specifications Safety CSA C22.2 No. 1010.1:1992 EMC EN50082-1:1992 and EN55022:1994 Class B Maximum voltage 30 V Mechanical and General Specifications Size 152 x 70 x 41 mm Weight 340 g Batteries One 9 V battery Warranty Three years Shock and vibration per MIL-T-28800 for a Class 2 Instrument Display current and % of span Yes Auto step, auto ramp Yes Span check Yes Loop Calibrators Data Sheet
