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.
The 771 mA Clamp Meter 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
