Product Description

Need more hours in your day?

Save time by NOT breaking the loop on 4-20 mA signal measurements.

Are you spending time:

  • Taking mA measurements by removing a wire and breaking the loop
  • Calling the control room to isolate a loop
  • Testing analog input/output on a console
  • Troubleshooting devices with mA inputs and outputs
  • Repairing intermittent or erratic 4-20 mA loops
  • Going back to the shop to get extra tools

If you need more time in your busy day take a good look at the Fluke 771 mA Clamp Meters. It’s designed to save you time, and money, by eliminating time wasting activities. Now you can troubleshoot and repair 4-20 mA loops without breaking the loop or bringing down the system.

Here are some specific ways the Fluke 771 Clamp Meters will help you:

Milliamp Clamp Features
