Key Features:
The Fluke 709H Precision mA Loop Calibrator combines high-accuracy loop calibration with powerful HART communication capabilities in a compact handheld instrument. Fluke designed this calibrator for instrumentation technicians and process engineers who need to commission, maintain, and troubleshoot HART-enabled devices more efficiently.
The Fluke 709H can source, simulate, and measure current signals up to 24 mA with 0.01% accuracy. As a result, technicians can perform precise loop calibration and verification tasks with confidence. The intuitive Quick-Set rotary knob also speeds up adjustments and simplifies day-to-day operation.
Built-in HART communication allows users to read device information, perform diagnostics, and trim transmitter outputs without requiring a dedicated communicator. In addition, technicians can access key HART parameters directly in the field, helping reduce maintenance time and improve productivity.
The integrated 24 V loop power supply supports simultaneous current measurement, while the selectable 250 Ω resistor simplifies testing on HART-compatible loops. Furthermore, onboard data logging captures both loop measurements and HART data for troubleshooting, loop tuning, and maintenance records.
Its rugged compact design withstands demanding industrial environments, while the large backlit display ensures clear visibility in low-light conditions. For professionals who require accurate calibration together with advanced HART diagnostics, the Fluke 709H offers a practical solution for modern process control applications.
