Fluke 709/709H Precision Loop Calibrators

• 0.01% accuracy for mA (0-24 mA) and voltage (0-30 VDC) measurements/sourcing. 

• Fluke 709H includes HART communication for device diagnostics, trimming, and configuration. 

• Quick-Set rotary encoder knob ensures fast, intuitive setup and operation. 

• Built-in 250-ohm HART resistor and 24 V loop power simplify testing. 

• Data logging (709H) captures 9800 records or 99 sessions, exportable via 709H/TRACK software. 

• Compact, rugged design with 40-hour battery life from six AAA batteries. 

• Simple two-wire connection and backlit LCD for use in dark, cramped spaces. 

The Fluke 709 and 709H Precision Loop Calibrators are sleek, powerful tools that streamline current loop calibration with pinpoint 0.01% accuracy for 0-24 mA and 0-30 VDC measurements. The 709H steps it up with HART communication, letting you read device info, run diagnostics, trim mA outputs, and store up to 20 device configurations—tasks once reserved for pricier communicators. Its data logging captures 9800 records or 99 sessions, exportable as .csv or .txt via 709H/TRACK software for troubleshooting and plant documentation.

Both models feature a Quick-Set rotary knob for fast setup, a built-in 250-ohm HART resistor, and 24 V loop power, all in a compact, rugged package that fits in your hand. The backlit LCD shines in dim, cramped spaces, and the two-wire connection keeps things simple. With 40 hours of battery life from six AAA batteries, overvoltage protection up to 240 VAC, and a three-year warranty, these calibrators are a technician’s ally for precise, efficient loop maintenance with a nod to modern connectivity.
