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 772 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.
