Fluke 709H Precision Current Loop Calibrator with HART Calibration

  • Best-in-class accuracy at 0.01 % reading
  • Compact rugged design
  • Intuitive user interface with quick-set knob for fast setup, easy use
  • 24 V dc loop power with mA measure mode (-25 % to 125 %)
  • Resolution of 1 µA on mA ranges and 1 mV on voltages ranges
  • Built in selectable 250 Ω resistor for HART communications
  • Simple two wire connection for all measurements
  • Auto shutdown to conserve battery life
  • Variable step and ramp time in seconds
  • Valve test (source and simulate defined mA values with % keys
  • Fast transfer of calibration data. The 709H/Track software/cable documents 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 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.
  • Built-in HART modem for communication capability to perform the following commands:
    • Read Message
    • Read Tag, Descriptor, Cal Date
    • Read Sensor PV info
    • Read PV Output info
    • Read Long Tag
    • Write PV Ranges (Upper and Lower)
    • Enter/Exit Fixed Current Mode
    • Set Zero Offset
    • Trim DAC Zero

The Fluke 709H Precision Current (mA) loop calibrators are designed to save time and produce high-quality results. The Fluke 709 calibrator is built around a user friendly interface with a quick-set rotary encoder knob. The Fluke 709H tool reduces the time it takes to measure, or source, 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.

The Fluke 709H adds HART communications and supports a select set of the HART universal and common practice commands. This makes the Fluke 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. The Fluke 709H will allow virtually any technician to service and support HART devices.
