  • 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:
