Fluke 773 Milliamp Process Clamp Meter
Milliamp process clamp meters can measure mA signals without breaking
the loop. The Fluke 773 mA Clamp Meter is Fluke’s premier mA Clamp
Meter, providing you with the best in troubleshooting and process
calibration power.
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

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
