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 |

- 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
