Fluke 773 Highlights

    Fluke 773 Overview

    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.

    Fluke 773 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
    • 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
    • mA in/out: simultaneously measure the mA signal with the clamp and source a mA signal
    • Voltage output linear ramp or 25% step output

    Each Fluke 773 Includes

    • Four AA alkaline batteries (installed)
    • Soft carrying case
    • TL75 test leads
    • AC 72 detachable clip
    • TL 940 mini hook test leads
    • Instruction sheet
    • Hanging tool with hook and loop strap
