Fluke 772 Milliamp Process Clamp Loop Meter

Key features Loop meter that measures 4 to 20 mA signals without breaking the loop Features best in class 0.2% accuracy Delivers 0.01 mA resolution and sensitivity Measures mA signals for PLC and control system analog I/O Product overview: Fluke 772 Milliamp Process Clamp Loop Meter Fluke 772 Milliamp Clamp Loop Meter measures, sources, and simulates 4-20 mA signals for testing control system I/O or IPs The Fluke 772 loop meter adds to the basic capabilities of the Fluke 771 to save more time and expand its applications. With the 771, you'll also be able to: source and simulate 4-20 mA signals for testing control system I/O; measure 4-20 mA signals with in-circuit measurement; power a transmitter with the 24 V loop power supply; and automatically ramp and step change the 4-20 mA output for remote testing. You'll be able to test 4–20 mA signals five times faster than with traditional DMMs, and without breaking the loop. That means you can troubleshoot a live device without having to power down, which can save you time, and help you avoid possibly missing something going on in the process. Other useful features: Simulates 4-20 mA signals for testing control system I/O Sources 4 to 20 mA signals for testing control system I/O or I/Ps Measures 4 to 20 mA signals with in-circuit measurement Includes simultaneous mA in-circuit measurement with 24V loop power for powering and testing transmitters Features a detachable clamp with extension cable for measurements in tight locations Captures and displays changing measurements with Hold function Offers mA output linear ramp or 25% step output Extends battery life with auto-off and backlight timeout Dual backlit display with both mA measurement and percent of 4 to 20 mA span Measurement Spotlight to illuminate hard to see wires in dark enclosures Measures 10 to 50 mA signals in older control systems using the 99.9 mA range Automatically changes the 4 to 20 mA output for remote testing Specifications: Fluke 772 Milliamp Process Clamp Loop Meter Specifications Diameter of measurable conductor 0.177” or 4.5 mm max Operating temperature -10 to 50ºC Storage temperature -25 to 60ºC Operating humidity < 90% @ <30ºC, < 75% @ 30 to 55ºC Operating altitude 0 to 2000 m IP rating IP 40 Size 44 x 70 x 246 mm (2 7/8 x 5 ¾ x 11 5/8 in) Weight 410 g, (14.4 oz) Vibration Random 2 g, 5 to 500 Hz Shock 1 meter drop test (except the jaw) EMI/RFI Meets EN61326-1 For current measurement w/ JAW, add 1mA to specification for EMC field strengths of 1V/m up to 3V/m.
