FLUKE 771 Milliamp Process Clamp Meter

The new Fluke 772 and 773 Milliamp Clamp Meters join the Fluke 771 to deliver a comprehensive range of test and measurement capabilities. Now technicians in process plants, industrial plants, commercial buildings and automation commissioning teams can choose exactly the range of capabilities they need, at a price that makes sense.

These precision tools are designed for instrumentation technicians, contractors and process vendors who install and commission instruments, process and automation technicians, commercial electricians and automation specialists who do mA loop troubleshooting on process control circuits, instruments and automation I/O.

The Fluke 771, 772 and 773 Milliamp Clamp Meters are engineered to accurately measure the minute amounts of current (4 to 20 mA signals) that flow through control system circuits, without having to shut down the system, break the circuit and insert a test instrument. Instead, sensitive current clamps placed on the wire detect and measure the current flowing through. Fluke is the only manufacturer making process mA clamp meters that don’t break the loop.

Features:
Best in class 0.2 % accuracy
0.01 mA resolution and sensitivity
Measure 4 to 20 mA signals without ”breaking the loop”
Measure mA signals for PLC and control system analog I/O
Dual backlit display with both mA measurement and percent of 4 to 20 mA span
Measurement Spotlight illuminates hard to see wires in dark enclosures
Detachable clamp with extension cable for measurements in tight locations
Measure 10 to 50 mA signals in older control systems using the 99.9 mA range
Automatically change the 4 to 20 mA output for remote testing
Power saving features, auto-off, backlight timeout extend battery life
Hold function captures and displays changing measurements
