Fluke 773 Milliamp Process Clamp Meters (tiedot englanniksi)

Need more hours in your day?

 

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.

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

  • 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
