Fluke 709H Caliberator

The Fluke 709H calibrator is designed with a user-friendly interface and features a quick-select rotary button. This tool reduces the time needed to measure or generate voltage or current and power a loop. The protective case fits comfortably in the technician's hand, and the large backlit display is easy to read, even in dark or cramped spaces.

The 709H offers:

• First-class precision with 0.01% of reading
• Compact and rugged design, operates on 6 standard AAA batteries
• Intuitive user interface with a quick-select rotary button for easy device configuration and use
• Integrated and selectable 250 Ω resistance for HART communication function
• 24 V DC loop power supply with mA current measurement mode (-25 to 125%)
• 1 µA resolution in mA current ranges and 1 mV in voltage ranges
• Simple two-wire connection for all measurements
• Auto-off function to extend battery life (adjustable up to 30 minutes)
• Variable step and ramp modes in seconds
• Adjustable scale selection (0 to 20 mA or 4 to 20 mA)
• Valve testing (simulation of defined mA values with % keys)

Specific HART Functions Include:

• Rapid transfer of calibration data. The system formed by the 709H, Track software and cable documents the parameters of all HART transmitters in your plant in .csv or .txt format.
• Recording or logging data from a particular transmitter to troubleshoot problems. The data logging function offers selectable capture intervals between 1 and 60 seconds and a recording capacity of 9,800 readings or 99 individual sessions. Each data sample includes the 709H measurement, the four process variables, and normal operating conditions.
