Product overview: Fluke 771 Milliamp Process Clamp Meter

Fluke 771 Milliamp clamp meter saves you time by measuring 4-20 mA signals without breaking the loop

The Fluke 771 delivers all the basics. It measures 4-20 mA signals without "breaking the loop", allowing you to measure low level dc current while 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 disruption to the process. For more convenience, the detachable clamp can be attached to the wire you're testing while you move the meter—connected by the extension cable—to a better viewing position. This is especially helpful for taking readings in tight locations.

Other useful features:

  • Captures and displays changing measurements with Hold function
  • 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

Reviews: Fluke 771 Milliamp Process Clamp Meter

Rated 5 out of 5 by from Time Saver This meter has saved me a lot of headaches. Makes troubleshooting so much simpler without having to interrupt a process by disconnecting wires to measure the current signals. Only Complaint is they are expensive. For the price you would think this meter would have a few more options.

Rated 4 out of 5 by from Quick and easy mA readings. I like how quick and easy it is to trouble shoot a loop without having to break the loop. Use it frequently.

Rated 2 out of 5 by from Basic ammeter...Easily broken Basic clamp-on ammeter for low voltage applications. Barely even used and a co-worker accidently dropped it from a very short distance causing the plastic hinge piece on the clamp to break...now it is useless until I buy a new clamp. Design is definitely not rugged so handle it with care!
