Fluke 707 4-20mA Loop Calibrator

The tool that lets you perform fast, one-handed loop checks. Just a "click"

This feature-rich solution combines the best features of push-button and rotary loop calibrators and offers:

• Large display and simple and quick interface to allow easy use with one hand.
• Simultaneous mA and % readings for quick and easy measurement interpretation.
• mA accuracy of 0.015% , better than other loop calibrators in this price range.
• 1 µA resolution for mA generation, simulation and measurement.
• Push button with 25% steps for quick and easy linearity checks.
• 0-100% “Span check” for quick confirmation of zero and span.
• Selectable slow, fast and step ramp functions to provide attenuated outputs for valve opening control and loop function tests.
• Internal 24 volt power supply, to be able to power and read a transmitter at the same time without having to carry a digital multimeter.
• Measures DC voltage up to 28V.
• One 9V battery, easy to replace without breaking the calibration seal
• Default operation at power up 0 - 20mA or 4 - 20mA.
• Innovative output adjustment selector with a resolution of 100 and 1 µA.
• HART ™ mode allows a 250 Ω resistor to be connected in series with a 24 V loop for compatibility with HART communication devices.
