Fluke releases 709H precision current loop calibrator with HART Communications
Fluke introduces the Fluke 709H precision current loop calibrator with HART Communications, 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.
The 709H 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. It also features a built-in, selectable 250-ohm 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.
