Current loop calibrator adds HART communications support

Fluke Corporation recently unveiled its Fluke 709H precision current loop calibrator with HART communications. The company's latest offering boasts 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. The Fluke 709H also comes with an accuracy of 0.01 per cent of reading.

The 709H supports a select set of HART universal and common practise 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 multi-function calibrator, or a laptop computer with a HART modem. It also features a built-in, selectable 250ohm resistor to tune the loop for HART communications.

The 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 per cent span and 25 per cent 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 upload to a PC.
