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.

Here are some specific ways the Fluke 772 Clamp Meters will help you:

 

Milliamp Clamp Features

Application

How it saves time and money

Measure mA signals for PLC and control system analog I/O without breaking the loop.

Measures low level dc current

Correlate process indication with real physical value

Measure output signals from transmitters without breaking the loop

Maintain and troubleshoot process and automation equipment without breaking the loop

No disruption to the process

Detachable clamp with extension cable

Measurements in tight locations

Enables measurements in difficult situations

Measurement Spotlight

Illuminates hard to see wires in dark enclosures

Measurement process is easier and quicker

Measure up to 99.9 mA range non-contact

Wide range of measurements

Measures 10 to 50 mA signals in older control systems

Automatic power off

After 15 minutes and 2 minute automatic off for backlight and spotlight

Saves battery life

The 772 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
  • Measure 4 to 20 mA signals with in-circuit measurement
  • Simultaneous mA in-circuit measurement with 24V loop power for powering and testing transmitters
  • Source 4 to 20 mA signals for testing control system I/O or I/Ps
  • mA output linear ramp or 25% step output
  • Automatically change the 4 to 20 mA output for remote testing
