Precision current loop calibrator with HART communication
May 2016Maintenance, Test & Measurement, Calibration
Comtest has introduced the new Fluke 709 and 709H mA loop calibrators, specifically designed to save time and produce high quality results. These calibrators are built around a user-friendly interface with a Quick-Set rotary encoder knob. This tool reduces the time taken to measure or source current and power up a loop. The protective holster fits easily into a technician’s hand and the large backlit display is easy to read, even in dark, cramped work areas.
The 709H adds HART communications and supports a select set of the HART universal and common practice commands. This makes it unique as both an affordable, compact loop calibrator and powerful HART communication troubleshooting tool. In the communicator mode the user will be able to read basic device information, perform diagnostic tests and trim the mA output 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 HART modem. The 709H will allow virtually any technician to service and support HART devices.
It can also store up to 20 HART device configuration files for uploading via 709H/TRACK software. Configurations can be stored as .csv or .txt files. This allows the end user to document plant HART. This feature gives the technician direct access to key device parameters, allowing better troubleshooting, calibrating and maintaining of plant assets.
