Save time and money by measuring output signals without shutting down the system

The Fluke 773 milliamp clamp meter is accurate, versatile and portable. You can measure 4–20 mA signals five times faster than traditional multimeters and without breaking the loop. That means you can troubleshoot a live device without powering down and missing something in the process.

The 773 is ideal for troubleshooting transmitters, valves and programmable logic controllers (PLCs) found in process plants. You can connect to a mA loop in a traditional series workflow to measure, source or simulate a control system. The 773 also measures up to 99.0 mA non-contact, including 10 to 50 mA signals in older control systems.

The 773 sources and measures DC voltage so it can be used to troubleshoot voltage input and output devices that accept a 1-5 V or 0-10 V signal. The clamp section of the meter detaches for use as a remote jaw, connected to the main body by an extension cable for easy measurements in tight spaces.

Work smarter with the 778 mA Clamp Meter

An integrated measurement spotlight allows you to illuminate hard to see wires in dark enclosures. A dual backlit display can show mA measurement and percent of 4 to 20 mA span simultaneously. The hold function captures measurements on-screen for verification and recording. The automatic power-off feature saves battery life so you can work longer.

Advanced loop troubleshooting

A unique mA scale feature can measure a mA signal without breaking the loop and output that signal to another device for recording. The 773 also includes simultaneous mA in-circuit measurement with 24 V loop power for powering and testing transmitters. You can also apply a mA input signal to a device and measure its 4-20 mA output on devices such as valves or mA isolators. The 773 offers mA or voltage output linear ramp or 25% step output.
