Fluke 771 – Milliamp Process Clamp Meter

The Fluke 771 delivers all the basic functionality you would expect in a milliamp clamp meter. It measures 4-20 mA signals without “breaking the loop,” allowing you to measure low level DC current without having to take systems offline for troubleshooting, saving downtime and money. You can also use it to measure output signals from transmitters without breaking the loop when maintaining and troubleshooting process and automation equipment. This saves time and avoids disrupting critical processes so you can avoid expensive downtime. You can also measure 10 to 50 mA signals in older control systems using the 99.9 mA range.Designed to make troubleshooting easier, the Fluke 771 includes a detachable clamp that can be attached to the wire you’re testing while you move the meterconnected by the extension cableto a better viewing position. This is especially helpful for taking readings in tight locations. With the dual backlit display showing both the mA measurement and the percent of a 4 to 20 mA span you can quickly understand what your system is doing, and a built-in LED spotlight lets you illuminate hard to see wire in dark enclosures. You can also capture and display changing measurements using the Hold function making it easier to verify and record measurements.IncludesSoft Carrying CaseQuick Reference GuideFeaturesMeasures 4 to 20 mA signals without breaking the loopBest in class 0.2% accuracyDelivers 0.01 mA resolution and sensitivityMeasures mA signals for PLC and control system analog I/ODetachable clamp for measurements in tight locationsSpecificationsDiameter of measurable conductor: 0.177 in or 4.5 mm maxOperating temperature: -10 to 50CStorage temperature: -25 to 60COperating humidity: <90% @ <30C, <75% @ 30 to 55COperating altitude: 0 to 2000 mIP rating: IP40Size: 59 x 38 x 212 mm (2.32 x 1.5 x 8.35 in)Weight: 260 g (9.1 oz)Vibration: Random 2 g, 5 to 500 HzShock: 1 m drop test (except the jaw)EMI/RFI: Meets EN61326-1Temperature coefficient: 0.01%/C (<18C or >28C)Power, battery life: 2x AA 1.5 V alkaline (IEC LR6), 40 hours typicalWarranty: Three years for electronics, one year for cable and clamp assemblymA measurement (measured by clamp)Resolution/range: 0 to 20.99 mAAccuracy: 0.2% + 2 countsResolution/range: 21.0 mA to 100.0 mAAccuracy: 1% + 5 counts
