Fluke 707 4-20mA Loop Calibrator

Calibrate, repair and maintain 4-20mA current loops with the Fluke 707 Loop Calibrator with 250 Ω resistor HART mode. It’s the high-performance, quickest, one-handed answer to loop calibration. The “Quick Click” detented knob allows for one-handed, quick loop checks. Just click and calibrate.

Key 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 250Ω HART resistor
• 0-28 VDC measurement to check Loop Voltage
• Easy battery exchange without opening the case
• Compact case with separate protective holster
• Three-year warranty
• 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 9V battery that is easily changed without breaking 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
