Calibrator communicates

The 709H Precision HART Loop Calibrator from Fluke, is an easy-to-use tool with a user-friendly interface and HART capabilities that reduces the time it takes to measure or source, voltage or current, and power up a loop. With its best-in-class accuracy at 0.01% of reading, the Fluke 709H is ideal for process technicians who need a precise loop calibrator and powerful HART communicator in one compact, rugged, reliable tool.

This calibrator supports a select set of HART universal and common practice commands. In the communicator mode, technicians can read basic device information, perform diagnostic tests, and trim the calibration on most HART-enabled transmitters. In the past, this could only be done with a dedicated communicator, a high-end multifunction calibrator, or a laptop computer with a HART modem. The 709H also features a built-in, selectable 250-ohm resistor to tune the loop for HART communications.

The Fluke 709H and non-HART 709 models feature an intuitive interface with dedicated buttons, a Quick-Set rotary encoder knob, and simple two wire connection for quick, easy measurements. The dedicated 0-100% span and 25% step buttons make for quick and easy testing. Ramping and auto-stepping enables technicians to perform tests remotely and be in ‘two places at once’.

The optional 709H/TRACK software with communication cable can document milliamp measurements and HART transmitter parameters and enable upload of data to a PC.
