Need more time?
Don’t break the loop on 4-20 mA signal measurements and save time.
Are you spending time?
- Taking mA measurements by removing a wire and breaking the loop
If you need more time in your busy day check out the Fluke 77X mA Clamp Meters. They are 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 77X 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. (771, 772 and 773)||Measures low level dc current||Correlate process indication with real physical value|
|Measure output signals from transmitters without breaking the loop (771, 772 and 773)||Maintain and troubleshoot process and automation equipment without breaking the loop||No disruption to the process|
|Detachable clamp with extension cable (771, 772 and 773)||Measurements in tight locations||Enables measurements in difficult situations|
|Source, simulate and measure mA signals in circuit (break the loop) (772 and 773)||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 (773 only)||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 (773 only)||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 (773 only)||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 (772 and 773)||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 (771, 772 and 773)||Clear measurement presentation||Allows quick measurement evaluation|
|Measurement Spotlight (771, 772 and 773)||Illuminates hard to see wires in dark enclosures||Measurement process is easier and quicker|
|Measure up to 99.9 mA range non-contact (771, 772 and 773)||Wide range of measurements||Measures 10 to 50 mA signals in older control systems|
|Automatic power off (771, 772 and 773)||After 15 minutes and 2 minute automatic off for backlight and spotlight||Saves battery life|
The 772 and 773 expand upon the capabilities of the popular 771 mA Clamp Meter. Now all you have to do is decide which model will help you save the most time.
The Fluke 771, 772 and 773 features:
- Best in class 0.2 % accuracy
772 and 773 add:
- Measure 4 to 20 mA signals with in-circuit measurement
773 Only Features:
- DC voltage measurement to verify 24V power supplies or voltage I/O signals
- Voltage output linear ramp or 25% step output
