Clamp Meters

FEATURES

  • Designed to verify the presence of load current, AC voltage and continuity of circuits, switches, fuses and contacts
  • These small and rugged clamp meters are ideally suited for current measurements up to 400 A in tight cable compartments.
  • Offers DC voltage measurements and has a higher resolution for loads below 40 A.

Earth Ground Clamp Meter

Earth Ground loop resistance measurements for commercial, industrial, and utility applications

  • Simplifies ground loop testing and enables non-intrusive leakage current measurement.
  • The compact and rugged design makes easy to use in small places and harsh environments, while the ‘display hold’ and the continuity testing with an audible alarm function ensures convenience in use.
  • Novel technique means that earth ground loop testing and continuity testing can be completed without breaking the circuit.
  • Uses the Stakeless testing method
    Eliminates the need to disconnect parallel ground rods and find suitable locations for placing auxiliary ground stakes.
  • Saves time and enables users such as industrial and utility electricians, and field service electricians and contractors, to perform earth ground loop tests in locations where it is not possible to use other techniques, including inside buildings or on power pylons.

Fluke Milliamp Process Clamp Meters

FEATURES

  • 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.

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. Have 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
