Overview The Fluke 707 loop calibrator is a high performance solution for calibration, repair, and maintenance of current loops. It combines the best features of a push-button and knob-base loop calibrator, for extremely fast and easy calibration. The large display and simple quick click rotary button lets you make quick selections and adjustments with one hand. Plus, features such as mA sourcing, simulation, and measurement; simultaneous display of mA and % of span, and selectable step or ramp outputs, helps you work more efficiently and accurately. And you can quickly change the 9V battery without breaking the calibration seal. Includes HART® compatible resistance connected in series with the loop supply for compatibility with HART communicators Features push button 25% steps for fast, easy linearity checks Includes 0-100% "span check" for fast confirmation of zero and span. Provides selectable slow ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop functional tests Includes a 24 volt internal loop supply, so you can power and read a transmitter at the same time without a DMM Measures V DC to 28 V Runs on a single 9 V battery that is easily changed without breaking the calibration seal Offers 0 - 20 mA or 4 - 20 mA default start up modes Features an innovative output adjustment dial. Comes with a protective yellow holster with test lead storage and a three year warranty Specifications Specifications Current measurement Range 0 to 24 mA Resolution 0.001 mA Accuracy 0.015% Rdg + 2 LSD Current sourcing Range 0 to 20 mA or 4 to 20 mA Accuracy 0.015% Rdg + 2 LSD Drive capability 1200 Ω 950 Ω at 20 mA in HART mode Current simulation Range 0 to 20 mA or 4 to 20 mA Accuracy 0.015% 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 0.015% Rdg + 2 LSD Environmental Specifications Operating temperature -10°C to 55°C Storage temperature -30°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 224 g (340 g including holster) Batteries One 9 V battery Alkaline 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
