The Fluke 773 Milliamp Process Clamp Meter measure 4 to 20 mA signals without "breaking the loop". The Fluke 773 meters can source 4 to 20 mA signals for testing control system I/O or I/Ps, simulate 4 to 20 mA signals for testing control system I/O and measure 4 to 20 mA signals with in-circuit measurement. They can also simultaneously measure milliamps in-circuit with 24 V loop power for powering and testing transmitters as well as source mA output signals in a linear ramp or 25% step output.

The Fluke 773 clamp meter offers advanced milliamp measurements features including a scaled mA output signal that enables another device to record the 4 to 20 mA signal without breaking the loop and the ability to simultaneously measure and source a mA signal, enhancing the meters troubleshooting ability.

In addition to advanced mA features, the Fluke 773 can measure and source DC voltage as well. The Fluke 773 can be used to verify 24 V power supplies or voltage I/O signals and source DC voltage to test input devices that accept a 1 to 5 volt or 0 to 10 volt signal.
