Use the Fluke 789 ProcessMeter™ with the ir3000 FC Connector to be in two places at once – source changing 4-20 mA signals at the control system while verifying control system responses remotely.

The Fluke 789 ProcessMeter is a handheld, battery-operated tool for measuring electrical parameters, supplying steady or ramping current to test process instruments, and providing a > 24 V loop power supply.

The Fluke 789 is the ultimate troubleshooting tool for electricians and instrumentation professionals, combining the functionality of a loop calibrator with the power of a digital multimeter. And with its built-in, selectable 250 ohm HART resistor, it eliminates the need to carry a separate resistor with you.
