  • The fastest, one-handed tool for loop checks.

    The Fluke 707 loop calibrator is a high performance solution for calibration, repair and maintenance of current loops. The new "Quick Click" knob making it extremely fast and easy to use. It features:

    • One handed user interface with "Quick Click" detented knob
    • mA sourcing, simulation and measurement
    • 0.015% accuracy and 0.001 mA resolution
    • Simultaneous mA and % of span display
    • Selectable step or ramp outputs
    • 24 V Loop supply with mA measure, including 250 Ω HART resistor
    • 0-28 V DC measurement to check Loop Voltage
    • Easy battery exchange without opening the case
    • Compact case with separate protective holster
    • Three year warranty
  • The fast, one-handed tool for loop checks. Just click to calibrate.

    This feature-rich solution combines the best features push-button and knob-base loop calibrator and offers:

    • Large display and simple, quick-click interface for easy one-handed operation.
    • Simultaneous mA and % readout for quick, easy interpretation of readings.
    • mA accuracy of 0.015%, superior to other loop calibrators in this price range.
    • 1 µA resolution for mA source, simulate and measure.
    • Push button 25% steps for fast, easy linearity checks.
    • 0-100% “span check” for fast confirmation of zero and span.
    • Selectable slow ramp, fast ramp, and step ramp 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.
    • Measures V DC to 28 V.
    • Single 9 V battery that is easily changed without braking calibration seal
    • 0 - 20 mA or 4 - 20 mA default start up modes.
    • Innovative output adjustment dial with 1 µA and 100 resolution.
    • HART ™ mode connects 250 Ω resistor in series with 24 V loop for compatibility with HART communicators.
