If you need more time in your busy day take a good look at the Fluke 772 and 773 mA Clamp Meters. 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.

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

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

Want simultaneous mA source/measure? Consider the Fluke 773 Milliamp Clamp Meter.

• Best in class 0.2% accuracy
• 0.01 mA resolution and sensitivity
• Measure 4 to 20 mA signals without “breaking the loop”
• Measure mA signals for PLC and control system analog I/O
• Dual backlit display with both mA measurement and percent of 4 to 20 mA span
• Measurement Spotlight illuminates hard to see wires in dark enclosures
• Detachable clamp with extension cable for measurements in tight locations
• Measure 10 to 50 mA signals in older control systems using the 99.9 mA range
• Automatically change the 4 to 20 mA output for remote testing
• Power saving features, auto-off, backlight timeout extend battery life
• Hold function captures and displays changing measurements
• Measure 4 to 20 mA signals with in-circuit measurement
• 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 24 V power supplies or voltage I/O signals
Source dc voltage to test input devices that accept a 1 to 5 volt or 0 to 10 volt signal
Scaled mA output corresponds to the 4 to 20 mA signal measured by the mA clamp 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
Voltage output linear ramp or 25 % step output
Automatically change the voltage output for remote testing
