    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 773 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 773 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

    Source, simulate and measure mA signals in circuit (break the loop)

    Confirm non-contact measurement. ve the next tool in hand for troubleshooting (source simulate)

    Eliminates the need to return to the shop to get a loop calibrator for troubleshooting after finding a bad signal with non-contact measurement

    Source and measure VDC

    Troubleshoot voltage input and output devices.

    Measure presence of 24V loop power. Measure 1 to 5 or 0 to 10V process signals. Test chart recorders

    4 to 20 mA In/out

    Dual channel mA source and measurement for troubleshooting

    Source 4 to 20 mA signals into valves and mA signal conditioners and simultaneously measure 4 to 20 mA positioning output signals.

    4 to 20 mA scaled output

    Scaled mA output provides a mA signal output representative of the measured mA value

    Connect a logging DMM and log the mA signal without breaking the loop

    Loop power supply

    Power a transmitter

    Substitute testing of the installed 24V loop power supply. Power a transmitter and measure its mA output signal for troubleshooting.

    Dual backlit display with both mA measurement and percent of 4 to 20 mA span

    Clear measurement presentation

    Allows quick measurement evaluation

    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 773 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
    • DC voltage measurement to verify 24V power supplies or voltage I/O signals
    • Source DC voltage to test input devices that accept a 1-5V or 0 to 10V signals
    • Scaled mA output provides a continuous mA signal that corresponds to the 4 to 20 mA signal measured by the mA clamp
    • Enables milliamp signal logging to a separate logging device without breaking the loop
    • Output mA signal enables a logging DMM or other device to record the 4- to 20 mA signal without breaking the loop
    • mA in/out: simultaneously measure the mA signal with the clamp and source a mA signal
    • Apply a mA input signal to a device and measure its’ 4-20 mA output on devices such as valves or mA isolators
    • Voltage output linear ramp or 25% step output
    • Automatically change the voltage output for remote testing
