A reliable, accurate, powerful mV mA Loop Calibrator with HART COMMUNICATOR featuring high accuracy of 0.01%. Save time and get high-quality results. The 709H adds HART communications and supports a select set of the HART universal and common practice commands. This makes the 709H 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. 709H will allow virtually any technician to service and support HART devices.

Supports HART general instructions and general application instructions. Able to read the device basic information, perform diagnostic testing and calibration to fine tune most HART transmitter, can store up to 20 HART device configuration file.
