Fluke 709H

The Fluke 709H mA loop calibrator is designed to save time and produce high-quality results. It includes HART communication 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 tool that offers:

  • Fast transfer of calibration data:The optional 709H/Track software/cable can document the parameters of all the HART transmitters in your plant, in either (.csv) or (.txt) format
  • Data logging or recording data on a particular transmitter for troubleshooting:The data log tool offers a selectable capture interval from 1 to 60 seconds and a logging capacity of 9800 records or 99 individual sessions. Each data sample contains the 709H measurement, all four process variables, and the standard status conditions.

Description

Key Features

  • mA precision loop calibrator that communicates with and tests HART smart instruments
  • Features best-in-class accuracy at 0.01% reading
  • Provides intuitive user interface with Quick-Set knob for fast setup
  • Includes built in selectable 250 Ω resistor for HART communication
  • Features 24 V DC loop power with mA measure mode (-25% to 125%)

In the communicator mode the user 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 HART modem. The Fluke 709H will allow virtually any technician to service and support HART devices.

And it’s easy to use. The Fluke 709H is built around a user-friendly interface with a Quick-Set rotary encoder knob. This reduces the time it takes to measure or source voltage or current, and power up a loop. The protective holster easily fits into a technician’s hand and the large backlit display is easy to read, even in dark, cramped worked areas.

Other useful features:

  • Provides resolution of 1 µA on mA ranges and 1 mV on voltage ranges
  • Quickly transfers calibration data for documentation in either (.csv) or (.txt) format with optional 709H/Track software/cable
  • Offers selectable capture interval from 1 to 60 seconds and a logging capacity of 9800 records or 99 individual sessions.
  • Features small rugged design and runs on six standard AAA batteries
  • Requires only simple two wire connection for all measurements
  • Provides Auto Shutdown to conserve battery life (adjustable up to 30 minutes)
  • Offers variable step and ramp time in seconds
  • Provides adjustable span selection (0 to 20 mA or 4 to 20 mA)
  • Includes valve test functionality (simulate defined mA values with % keys)
